EXTON, Pa.--(BUSINESS WIRE)--

In collaboration with Fibrocell Science, Inc., (OTCBB:FCSC.OB), researchers at the University of California, Los Angeles (UCLA) have identified two rare adult stem cell-like subpopulations in adult human skin, a discovery that may yield further ground-breaking research in the field of personalized medicine for a broad range of diseases. Using technology developed by Fibrocell Science, Inc. the researchers were able to confirm the existence of these two types of cells in human skin cell cultures, potentially providing a source of stem cell-like subpopulations from skin biopsies, which are quicker to perform, relatively painless and less invasive than bone marrow and adipose tissue extractions, which are the current methods for deriving adult stem cells for patient-specific cellular therapies.

The findings, which are reported in the inaugural issue of BioResearch Open Access, pertain to two subtypes of cells: SSEA3-expressing regeneration-associated (SERA) cells, which may play a role in the regeneration of human skin in response to injury and mesenchymal adult stem cells (MSCs), which are under investigation (by many independent researchers) for their ability to differentiate into the three main types of cells: osteoblasts (bone cells), chondrocytes (cartilage cells) and adipocytes (fat cells). Finding these specialized cells within the skin cell cultures is important because rather than undergoing a surgical organ or tissue transplantation to replace diseased or destroyed tissue, patients may one day be able to benefit from procedures by which stem cells are extracted from their skin, reprogrammed to differentiate into specific cell types and reimplanted into their bodies to exert a therapeutic effect. Research in this area is ongoing.

Finding these rare adult stem cell-like subpopulations in human skin is an exciting discovery and provides the first step towards purifying and expanding these cells to clinically relevant numbers for application to a variety of potential personalized cellular therapies for osteoarthritis, bone loss, injury and/or damage to human skin as well as many other diseases, said James A. Byrne, Ph.D., the studys lead author and Assistant Professor of Molecular and Medical Pharmacology at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. In addition to pursuing our own research investigations with Fibrocell Science using this method, we envision a time not too far in the future when we will be able to isolate and produce mesenchymal stem cells and SERA cells on demand from skin samples, which may allow other researchers in need of specialized cells to pursue their own lines of medical and scientific research.

We congratulate the UCLA researchers on the publication of their breakthrough data, which may ultimately lead to new patient-specific, personalized cellular therapies to treat various diseases, said David Pernock, Chairman and CEO of Fibrocell Science, Inc. Fibrocell Science is proud of our role in helping to establish the potential of dermal skin cells for the future of personalized, regenerative medicine. We look forward to continuing our relationship with UCLA and Dr. Byrnes team to advance this research.

Discovering Viable, Regenerative Cells in the Skin

Dr. Byrne and colleagues confirmed previous research identifying a rare population of cells in adult human skin that has a marker called the stage-specific embryonic antigen 3 (SSEA3). Dr. Byrne observed that there was a significant increase in the number of SSEA3 expressing cells following injury to human skin, supporting the hypothesis that the SSEA3 biomarker can be used to facilitate the identification and isolation of these cells with tissue-regenerative properties.

Using Fibrocells proprietary technology, the researchers collected cells from small skin samples, cultured the cells in the lab, and purified them via a technique known as fluorescence-activated cell sorting (FACS). Under FACS, cells in suspension were tagged with fluorescent markers specific for undifferentiated stem cells. This method allowed the researchers to separate the rare cell subpopulations from other types of cells.

Dr. Byrne and colleagues also observed a rare subpopulation of functional MSCs in human skin that existed in addition to the SERA cells.

Being able to identify two sub-populations of rare, viable and functional cells that behave like stem cells from within the skin is an important finding because both cell types have the potential to be investigated for diverse clinical applications, said Dr. Byrne.

PHILADELPHIA HIV patients treated with genetically modified T cells remain healthy up to 11 years after initial therapy, researchers from the Perelman School of Medicine at the University of Pennsylvania report in the new issue of Science Translational Medicine. The results provide a framework for the use of this type of gene therapy as a powerful weapon in the treatment of HIV, cancer, and a wide variety of other diseases.

"We have 43 patients and they are all healthy," says senior author Carl June, MD, a professor of Pathology and Laboratory Medicine at Penn Medicine. "And out of those, 41 patients show long term persistence of the modified T cells in their bodies."

Early gene therapy studies raised concern that gene transfer to cells via retroviruses might lead to leukemia in a substantial proportion of patients, due to mutations that may arise in genes when new DNA is inserted. The new long-term data, however, allay that concern in T cells, further buoying the hope generated by work June's team published in 2011 showing the eradication of tumors in patients with chronic lymphocytic leukemia using a similar strategy.

"If you have a safe way to modify cells in patients with HIV, you can potentially develop curative approaches," June says. "Patients now have to take medicine for their whole lives to keep their virus under control, but there are a number of gene therapy approaches that might be curative." A lifetime of anti-HIV drug therapy, by contrast, is expensive and can be accompanied by significant side effects.

They also note that the approach the Penn Medicine team studied may allow patients with cancers and other diseases to avoid the complications and mortality risks associated with more conventional treatments, since patients treated with the modified T cells did not require drugs to weaken their own immune systems in order for the modified cells to proliferate in their bodies after infusion, as is customary for cancer patients who receive stem cell transplants.

To demonstrate the long-term safety of genetically modified T cells, June and colleagues have followed HIV-positive patients who enrolled in three trials between 1998 and 2002. Each patient received one or more infusions of their own T cells that had been genetically modified in the laboratory using a retroviral vector. The vector encoded a chimeric antigen receptor that recognizes the HIV envelope protein and directs the modified T cell to kill any HIV-infected cells it encounters.

As is standard for any trial, the researchers carefully monitored patients for any serious adverse events immediately after infusion -- none of which were seen. Additionally, because of the earlier concerns about long-term side effects, the U.S. Food and Drug Administration also asked the team to follow the patients for up to 15 years to ensure that the modified T cells were not causing blood cancers or other late effects. Therefore, each patient underwent an exam and provided blood samples during each of the subsequent years.

Now, with more than 500 years of combined patient safety data, June and colleagues are confident that the retroviral vector system is safe for modifying T cells. By contrast, June notes, the earlier, worrying side effects were seen when viral vectors were used to modify blood stem cells. The new results show that the target cell for gene modification plays an important role in long-term safety for patients treated. "T cells appear to be a safe haven for gene modification," June says.

The multi-year blood samples also show that the gene-modified T cell population persists in the patients' blood for more than a decade. In fact, models suggest that more than half of the T cells or their progeny are still alive 16 years after infusion, which means one treatment might be able to kill off HIV-infected cells for decades. The prolonged safety data means that it might be possible to test T cell-based gene therapy for the treatment of non-life threatening diseases, like arthritis.

"Until now, we've focused on cancer and HIV-infection, but these data provide a rationale for starting to focus on other disease types," June says. "What we have demonstrated in this study and recent studies is that gene transfer to T cells can endow these cells with enhanced and novel functions. We view this as a personalized medicine platform to target disease using a patient's own cells."

SAN DIEGO, CA--(Marketwire -05/03/12)- Regen BioPharma (Regen), Inc. a newly-formed subsidiary of Bio-Matrix Scientific Group, Inc. (BMSN.PK - News) (BMSN.PK - News), unveiled today its operational plan for its "Super-Incubator" stem cell company.

Month 1-2: Assembly of Team. Regen intends to assemble a team of world-class leaders in the spheres of Technology, Intellectual Property assessment, valuation and Clinical development. Regen will seek to compile a team of Physician-Scientists with experience in the area of clinical trials for regenerative medicine/stem cell products, Regulatory experts who have successfully taken products through the FDA and corresponding agencies internationally, and Biotech Entrepreneurs who have track records of excellence in business formation and value optimization.

Month 1-4: In-licensing of Intellectual Property. The Company having already assessed over 20,000 issued patents and having compiled a shortlist of 30 targets; Regen will seek to execute licensing deals on an initial core of 3 technologies. Regen focuses on issued patents that have already passed preclinical studies but are not under clinical development.

Month 3-6: Interaction with Regulatory Agencies. Regen intends to develop data packages for each of the technologies and initiate interaction with Regulatory Agencies such as the FDA for initiation of trials.

Month 6-18: Clinical Implementation. Regen intends to launch clinical trials with world-leading institutions to obtain human safety data and "signal" of therapeutic efficacy.

Month 18-24: Exit. It is intended that technologies "incubated" by Regen will be spun off either as separate companies, or sold to Large Pharma companies seeking to enhance their therapeutic pipeline.

"At present there exists a wealth of intellectual property that is 'collecting dust' in the corridors of Academia. Given the field of regenerative medicine and stem cell therapy is so young, and the business models are fuzzy at best in terms of valuation, we see this space as a unique opportunity for acceleration of clinical development/value optimization," said Bio-Matrix Chairman & CEO David Koos about its Regen BioPharma. "Valuations for stem cell companies that have passed the threshold of clinical safety, with signals of efficacy are astronomical. The $1.8 billion Mesoblast-Cephalon deal, as well as recent financings of private companies with as little as 3 patient data such as Promethera ($31 million) or Allocure with 16 patients ($23 million), is testimony to the extremely high valuations that are characteristic of this space."

BioTime, Inc. (NYSE Amex: BTX) announced today that Charles S. Irving, Ph.D., the CEO of BioTimes subsidiary Cell Cure Neurosciences, Ltd. will provide an update on the development of OpRegen at an investor meeting in New York City. In his presentation, Dr. Irving will describe the unmet medical needs and markets for the treatment of the dry form of age-related macular degeneration (AMD), and the advantages of Cell Cures OpRegen which has been produced from human embryonic stem cells in culture conditions free of animal products, eliminating the need for designating the product as a xenotransplantation therapeutic. Dr. Irving will also discuss Cell Cures collaboration with Teva Pharmaceutical Industries Ltd., under which Teva has the option to develop and commercialize both OpRegen and OpRegen-Plus. Dr. Irving will describe the nature of the ongoing preclinical studies which are expected to lead to regulatory filings for the initiation of human clinical trials in 2013. Dr. Irvings presentation will be available on BioTimes web site http://www.biotimeinc.com as well as Cell Cure Neurosciences web site at http://www.cellcureneurosciences.com.

Background.

Age-related macular degeneration is the leading cause of blindness in an aging population. It is widely believed that the loss or dysfunction of a particular type of cell called retinal pigment epithelial (RPE) cells is the root cause of the disease. While therapies exist to treat what is called the wet form of macular degeneration exist, there are no therapies for the dry form. The transplantation of healthy RPE cells may provide a superior treatment for this devastating disorder. Cell Cures OpRegen is xeno-free, meaning that no animal products were used in the culture of the human embryonic stem cell-derived RPE cells. The use animal products to culture cells often results in the designation of the therapy as a xenotransplantation product, even though the cells themselves are of human origin. Xenotransplantation may raise purity issues, increasing the costs of product development along with other risks and uncertainties. The production of animal product-free OpRegen will therefore eliminate concerns of xenotransplantation and may provide cost savings in development and production should the product successfully complete clinical trials and be approved for human use.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Data and Safety Monitoring Board (DSMB), an independent group of medical experts closely monitoring the Companys three ongoing clinical trials, have recently authorized the Company to move forward with enrollment and treatment of additional patients with Stargardts disease (SMD). In the U.S. SMD trial, ACT will screen and enroll patients for the second cohort, who, in keeping with trial protocol, will be injected with 100,000 retinal pigment epithelial (RPE) cells - as compared with the 50,000 cell dose used in the patients of the first cohort. The Company has also been approved to treat the final two patients to round out the initial dosing arm in its European trial. The use of pluripotent stem cells to derive RPE cells, and the use of the resulting RPE cells for treating a wide range of macular degenerative disorders, are covered by a robust patent portfolio owned by ACT, including a number of issued broad patents in key world markets.

DSMB authorization to move to the next higher dosage of cells in our U.S. clinical trial and complete the treatment of the first cohort of patient in our European trial represents yet another significant advancement for our clinical programs, commented Gary Rabin, chairman and CEO of ACT. We are pleased with the pace of progress and the continued finding of safety amongst the participants in both the U.S. and European trials. The results so far have been encouraging, and with our SMD programs having been granted orphan medicinal product designation in both the U.S. and Europe, we look forward to eventually reaching a stage at which we can further avail ourselves of all the regulatory and financial benefits this designation brings.

The three procedures comprising the first cohort of patients in the U.S. SMD trial were all conducted at University of California at Los Angeles (UCLA), by Steven Schwartz, M.D., Ahmanson Professor of Ophthalmology at the David Geffen School of Medicine at UCLA and retina division chief at UCLA's Jules Stein Eye Institute. The first procedure in the E.U. trial was conducted at Moorfields Eye Hospital in London, by a team of surgeons led by Professor James Bainbridge, consultant surgeon at Moorfields and Chair of Retinal Studies at University College London.

We are gratified to be moving to the next stage in both of our SMD trials, commented Robert Lanza, M.D., ACTs chief scientific officer. We remain very encouraged by the preliminary data in the first four SMD patients treated with the lowest dose of RPE cells at UCLA and Moorfields Eye Hospital. We are doubling the number of cells that will be transplanted in the next group of patients in the U.S. trial. We will be anxious to see if the higher dosage of RPE cells will impact visual function and photoreceptor rescue.

ACT is conducting three clinical trials in the U.S. and Europe using hESC-derived RPE cells to treat forms of macular degeneration. Each trial will enroll a total of 12 patients, with cohorts of three patients each in an ascending dosage format. These trials are prospective, open-label studies, designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation into patients with dry-AMD or Stargardt's macular dystrophy (SMD) at 12 months, the studys primary endpoint. On January 20, 2012, the first SMD patient enrolled in the Companys U.K. clinical trial was treated at Moorfields Eye Hospital in London. The final patient of the first cohort in the companys SMD trial in the U.S. was treated on February 13, 2012.

Further information about patient eligibility for the dry AMD study and the concurrent study on SMD is also available on http://www.clinicaltrials.gov; ClinicalTrials.gov Identifiers: NCT01345006, NCT01469832 and NCT01344993.

GRAND RAPIDS, Mich., April 19, 2012 /PRNewswire/ --Researchers at Lund University in Sweden have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types -- most importantly, they can form new brain cells. Scientists hope to take advantage of the finding to develop methods to heal and repair disease and injury in the brain.

Analyzing brain tissue from biopsies, the researchers for the first time found stem cells located around small blood vessels in the brain. The cell's specific function is still unclear, but its plastic properties suggest great potential.

"A similar cell type has been identified in several other organs where it can promote regeneration of muscle, bone, cartilage and adipose tissue," said Patrik Brundin, M.D., Ph.D., Jay Van Andel Endowed Chair in Parkinson's Research at Van Andel Research Institute (VARI), Head of the Neuronal Survival Unit at Lund University and senior author of the study.

In other organs, researchers have shown clear evidence that these types of cells contribute to repair and wound healing. Scientists suggest that the curative properties may also apply to the brain. The next step is to try to control and enhance stem cell self-healing properties with the aim of carrying out targeted therapies to a specific area of the brain.

"Our findings show that the cell capacity is much larger than we originally thought, and that these cells are very versatile," said Gesine Paul-Visse, Ph.D., Associate Professor of Neuroscience at Lund University and the study's primary author. "Most interesting is their ability to form neuronal cells, but they can also be developed for other cell types. The results contribute to better understanding of how brain cell plasticity works and opens up new opportunities to exploit these very features."

The study, published in the journal PLoS ONE, is of interest to a broad spectrum of brain research. Future possible therapeutic targets range from neurodegenerative diseases to stroke.

"We hope that our findings may lead to a new and better understanding of the brain's own repair mechanisms," said Dr. Paul-Visse. "Ultimately the goal is to strengthen these mechanisms and develop new treatments that can repair the diseased brain."

New Stem Cell Found in the Brain

SEATTLE and SINGAPORE, April 19, 2012 /PRNewswire/ -- Cell Therapeutics, Inc.("CTI") (Nasdaq and MTA: CTIC) and S*BIO Pte Ltd announced today that the companies have entered into an asset purchase agreement pursuant to which CTI would acquire world-wide rights to S*BIO's pacritinib, a highly selective JAK2 inhibitor. Pacritinib is an oral JAK2 (Janus Associated Kinase 2) selective inhibitor that has demonstrated encouraging clinical benefit in phase 1 and 2 clinical studies in patients with primary myelofibrosis (MF) or MF secondary to other myeloproliferative neoplasms (MPN). Pacritinib has orphan drug designation in the U.S. and Europe for myelofibrosis.

"JAK2 dysregulation is associated with a broad range of difficult-to-treat illnesses, including cancers and autoimmune diseases, and is one of the most exciting potential new targets in cancer therapy today," said James A. Bianco, M.D., CEO of Cell Therapeutics, Inc. "We believe a highly selective JAK2 inhibitor that also inhibits the JAK2 clonal mutation (JAK2V617F) offers a distinct biological and clinical advantage over marketed or development stage compounds which are non-selective inhibitors of the JAK pathway. We believe that the lack of suppression of red blood cell and platelet formation seen with pacritinib has the potential to satisfy a medical need not currently addressed with existing non-selective JAK1/JAK2 inhibitors."

"The acquisition of pacritinib is aligned with our strategy of becoming a leader in the treatment of blood related cancers and disorders. We are looking forward to build on the progress made by S*BIO," Bianco continued. "With Pixuvri approaching approval and launch in the EU, and tosedostat and pacritinib entering phase 3 our late stage portfolio addresses a full complement of blood related cancers ranging from MPN to MDS, leukemia and lymphoma."

"JAK inhibitors are a very exciting new class of targeted agents that provide effective treatment in a previously difficult to treat disease called myelofibrosis," stated Srdan Verstovsek, M.D., Ph.D., Associate Professor, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, Texas and Executive Committee Member, International Working Group for Myelofibrosis. "Pacritinib is a highly specific JAK2 inhibitor that does not appear to cause suppression of platelets or red blood cells as seen with other treatments, while reducing enlarged spleen and improving disease related debilitating symptoms in patients with myelofibrosis. I am looking forward to working with Cell Therapeutics in developing this agent for patients with myelofibrosis who present with low blood counts or develop them on therapy."

"We are most impressed with CTI's experienced team and believe that they are the ideal company to further develop pacritinib, S*BIO's most advanced program," commented Ms. Tamar Howson, S*BIO's CEO. S*BIO is a privately-held biotechnology company focused on the research and clinical development of novel targeted small molecule drugs for the treatment of cancer with leading programs around kinases and histone deacetylases (HDAC). S*BIO has strong links with a network of medical oncologists in Asia Pacific and its investors include Bio*One Capital a subsidiary of EDBI, Aravis Ventures, Mitsui Ventures and other international funds.

Pursuant to the terms of the agreement, CTI will make an upfront payment of $15 million and issue $15 million shares of unregistered preferred stock convertible into common stock in CTI. The agreement also includes regulatory success- and sales-based milestone payments, as well as single digit royalties on net sales. CTI will be solely responsible for development and commercialization activities of pacritinib worldwide. The agreement will be subject to satisfaction of certain closing conditions. The terms of the agreement will be provided in more detail in a Form 8-K to be filed with the U.S. Securities and Exchange Commission.

About Janus Associated Kinase (JAK)

The JAK family of enzymes are a central component in signal transduction pathways, which are critical to normal blood cell growth and development as well as inflammatory cytokine expression and immune responses. When dysregulated by activating mutations, uncontrolled blood cell growth can occur accompanied by inflammation and immune system activation contributing to disease manifestations in MPN. Autoimmune diseases such as psoriasis and rheumatoid arthritis also have activation of this pathway and JAK inhibitors are in development for these disorders. In addition, activation of the JAK2 pathway and the related FLT3 pathway (whether by activating mutations or other causes) is frequently associated with leukemia, and lymphoma. Pacritinib inhibits both JAK2 and FLT3 suggesting potential use in treating such blood related cancers.

Myelofibrosis is a stem cell-derived clonal myeloproliferative disease frequently associated with a mutation in the JAK2 gene (JAK2V617F). Inhibition of JAK1/ JAK2 has recently been shown to lead to clinical benefit in patients with advanced MF and platelet counts of 100,000 or higher at study entry, resulting in the first JAK1/JAK2 inhibitor to be approved for patients with advanced MF. The approved JAK inhibitor is not selective for JAK2 but inhibits both JAK1 and JAK2. While effective in reducing patients symptoms associated with MF, JAK1/JAK2 inhibitors frequently cause suppression of platelets and red blood cells, often leading to a need for red blood cell transfusions. Pacritinib may offer an advantage over other JAK inhibitors by having less bone marrow suppression. Such agents may also lead to a modification of the underlying disease process by selectively affecting the malignant clone expressing JAK2V617F.

Cell Therapeutics Enters into Agreement to Acquire Pacritinib, a Novel Highly Selective JAK2 Inhibitor Phase 3 ...

California's $3 billion stem cell agency, now more than 7 years old, has joined research partnerships with science and health agencies in eight foreign countries, the San Francisco institute announced.

The agreements call for collaboration in efforts aimed at speeding stem cell research from the laboratory to the hospital, where researchers hope that basic human cells will be programmed to treat scores of human degenerative diseases.

Research partnerships between American and foreign stem cell scientists are encouraged, but the California institute's funds would only be spent within the state, institute officials said.

Alan Trounson, president of the California Institute for Regenerative Medicine, signed agreements with stem cell funding agencies in Brazil and Argentina last week, he said Thursday.

"Both Brazil and Argentina have strong and robust stem cell research communities in basic science and transitional clinical science, which should create exciting synergies with many scientists in California," Trounson said in a statement.

He has signed similar pacts with stem cell agencies in Canada, Britain, France, Spain, Australia, Japan, China and Indiana.

The California institute was created in 2004 after Proposition 71, a $3 billion bond issue, was approved by California voters at a time when use of federal funds was barred for research into the promising field of embryonic stem cells.

So far the state agency has committed $1.2 billion to scientists and training centers at 56 California institutions, and the rest of the bond money should last until 2020, a spokesman said.

Stem cell institute to work with foreign agencies

The Catholic Church has never had a particularly easy relationship with science. After all, this is the institution that sentenced Galileo Galilei as a heretic for his theories on the universe during the Roman Inquisition. Two thousand years later, the church forgave Galileo and called the whole misunderstanding a tragic mutual incomprehension but it remains safe to say the Vatican doesnt have a great track record when it comes to empirical open-mindedness.

So onlookers were surprised when the Vatican announced it would be hosting a global conference on the highly controversial issue of stem-cell research in Rome over four days in late April. The church held a similar conference in 2010 and 2011, which focused on its recommendation that stem-cell research should be limited to adult cells that can be harvested from live donors, not embryonic cells that destroy the source. But this years conference schedule featured some of the worlds foremost experts in embryonic research as keynote speakersleading some scientists to think that the Vatican might actually be looking for enlightenment on the topic.

That was not exactly case. Instead, the Vatican seems to have hoped that by including embryonic researchers in the program, it would appear that these scientists actually endorsed the Vaticans stance.

It might have worked to some extent, but after some of the speakers declined to censor their speeches, the Vatican abruptly canceled the conference altogether. According to the conference website, the event was canceled due to serious economic and logistic-organizational reasons that have completely jeopardized the success of the 3rd International Congress on Responsible Stem Cell Research. The scientists who were planning to attend say they are being stifled instead. I think the only interpretation is that we are being censored, Alan Trounson, president of the California Institute for Regenerative Medicine in San Francisco, said in a statement. It is very disappointing that they are unwilling to hear the truth.

Just what was the Vatican thinking? Inviting embryonic stem-cell researchers to a conference and then denying them the right to talk about their field of expertise was a major gamble. Had the speakers agreed to avoid reference to embryonic research, it would have given the disingenuous impression that they endorse the Holy Sees recommendation on adult stem-cell research only. Did the Vatican really think they could control the scientific community? Apparently so. Father Scott Borgman of the Pontifical Academy for Life, which co-organized the conference, had reportedly asked the speakers to limit their discussions to adult stem-cell research only. George Daly, a leading embryonic researcher with the Childrens Hospital in Boston, says he was actually told not to make embryonic researchhis field of expertisea focal point of his talk. When he told Borgman that he would still be touching on the topic in a historical context, higher-ups in the Vatican reportedly panicked. I had been encouraged to think that the Congress would be a forum for discussion of many areas of common interest to the Vatican and stem cell scientists, regardless of the disagreements over embryonic stem cells, Daly told The Daily Beast. We should all agree that clinical trials of new medical treatments based on stem cells should proceed according to rigorous principles to ensure patients are kept as safe as possible and free from exploitation. And we should all agree that premature claims of therapeutic efficacy and direct marketing of unproven interventions to vulnerable patients is a threat to legitimate attempts to develop experimental stem cell medicines.

With the cancelation of the event, discourse between the two diverse entities will not have a venue. One Vatican official told the Catholic News Service that many of the Vaticans leaders were secretly glad the conference failed. I am infinitely relieved that the church has avoided a major blunder which would have confused the faithful for decades to come, the unnamed source said. The Holy Spirit has certainly shown to be present through those faithful members who drew attention to the ambiguity of the choice of speakers. I hope and pray that a review will be affected of the basis on which these congresses are planned.

Some stem-cell researchers are also relieved the conference wont go on. I personally am very uncomfortable with a scientific meeting run by a church, and one at which only certain types of science and scientists are allowed to attend, blogged Paul Knoepfler, an associate professor of Cell Biology and Human Anatomy at UC Davis School of Medicine who blogs about stem cell research at IPCell.com. Also I cant help but wonder, what would be the reaction if someone like Daley spent a few minutes of his talk discussing his embryonic cell research in a very nonconfrontational way? Would he be tasered or drop through some trap door straight to Hell?

Still, Knoepfler was hopeful. I view the canceled Vatican stem-cell meeting as a missed opportunity for a very much needed, open dialogue about stem cells, he told The Daily Beast. More specifically, I believe the reasons for the cancellation reflect an anti-scientific attitude by the highest level of Vatican leaders. More simply put, the attitude might be summed up by the phrase If you do not think like us, you are not welcome at our meeting, and well go so far as to cancel the whole thing to avoid your presence.

Inviting embryonic stem-cell researchers to a conference and then denying them the right to talk about their field of expertise was a major gamble.

Stem Cells: Galileo 2.0?

LOS ANGELES Blocking "don't destroy me" signals that normally sit on the surface of tumor cells and render them resistant to immune-cell attack slows the growth of a broad range of human cancers when they're implanted in mice, researchers have found.

The approach, reported by immunologists at the Stanford University School of Medicine, was effective against ovarian, breast, colon, bladder, liver, prostate and brain cancer cells. If the work can be repeated in people, the approach may someday help doctors marshal defender cells in patients' own bodies to fight cancers, the researchers said.

Key to the work is a cell protein called CD47, which is already being investigated in the treatment of leukemia.

CD47 sits on cell membranes and communicates with various immune cells, including macrophages, which gobble up foreign invaders in the body. It plays an important role in the normal life cycle of healthy red blood cells, telling macrophages to leave the cells alone.

In the study, the scientists injected the animals with antibodies that bind to CD47 and block out its protective signal.

"If we can block this signal, we can get the immune system to eat (the cancer cells) up," said Stephen Willingham, a postdoctoral researcher in the laboratory of immunologist Dr. Irving Weissman at Stanford and first author of a paper about the work.

The Stanford team examined cancer cells removed from patients with a variety of types of solid tumors. It found that CD47 studded the membranes of almost all of the cancer cells in their sample, suggesting that it is a molecule common to all cancers.

Placing the cells in lab dishes, the team administered an antibody: a protein that binds to CD47 and blocks it from warding off immune system cells. Macrophages ate the cells.

The researchers then implanted human tumor cells in mice for further study. They allowed the cancers to grow, and administered the antibody against CD47.

Antibody treatment inhibited the growth of almost all of the solid tumors and was able to wipe out some smaller cancers altogether, according to the report, which was published Monday in the journal Proceedings of the National Academy of Sciences.

A Monsignor and Officer for Studies at the Pontifical Academy for Life called the cancellation a "sad event." Attendees are set to receive an official explanation

March 26, 2012|

By Ewen Callaway of Nature magazine

The Vatican has abruptly cancelled a controversial stem-cell conference that was set to be attended by the Pope next month.

The Third International Congress on Responsible Stem Cell Research, scheduled for 25-28 April, was to focus on clinical applications of adult and reprogrammed stem cells. But a number of the invited speakers, including Alan Trounson, president of the California Institute for Regenerative Medicine in San Francisco, and keynote speaker George Daley, a stem-cell scientist at Children's Hospital Boston in Massachusetts, are involved in research using human embryonic stem cells, which the Catholic Church considers unethical. The previous two congresses had also included scientists who worked on such cells, without generating much controversy.

Father Scott Borgman, secretary of the Church's Pontifical Academy for Life, one of the conference organizers, says that logistical, organizational and financial factors forced the cancellation, which was announced on 23 March. The academy weighs in on bioethical and theological issues that are relevant to Church teachings.

The Catholic News Agency, an independent news service based in Englewood, Colorado, quoted an unnamed academy member who called the cancellation an "enormous relief to many members of the Pontifical Academy for Life, who felt that the presence on its program of so many speakers, including the keynote speaker, committed to embryonic stem cell research, was a betrayal of the mission of the Academy and a public scandal".

"I think the only interpretation is that we are being censored. It is very disappointing that they are unwilling to hear the truth," says Trounson. He had hoped to provide a "balanced perspective" on the potential clinical applications of stem cells, both adult and embryonic.

Meanwhile, some European scientists, who had called for a boycott because they believed the conference unfairly maligned embryonic stem cell research, cheered its cancellation.

SACRAMENTO (KABC) -- Eight years ago voters agreed to fund California's stem cell agency, hoping it would yield new treatments for various conditions. Now the agency is running out of funds and any practical cures are still years away.

The California Institute for Regenerative Medicine (CIRM) is about to enter a crucial stage in stem cell research: going to clinical trials. The most promising experiments could cure diabetes, HIV, sickle-cell anemia and blindness in the elderly.

"You don't really get to find out whether the potential of the treatment is really going to be effective until you start to treat the patients," said Alan Trounson, president of the California Institute for Regenerative Medicine.

CIRM's board is discussing how much to allocate for that trial phase. Through voter-approved bonds under Proposition 71 (The California Stem Cell Research and Cures Act), it has already given out or spent half of the $3 billion, but despite the medical promise, there's little to show for it beyond basic research and several high-tech laboratories.

But the agency says the breakthroughs will come over the next few years, way ahead of the rest of the world.

"This would all be happening in California, all driven by this Proposition 71 money," said Trounson.

The bond money is expected to last only several more years. One option is to ask voters to approve more bonds, something taxpayer groups oppose.

"When people think about bond financing, they think about a bridge, a school, a canal," said Jon Coupal, president of the Howard Jarvis Taxpayers Association. "But stem cell research is just kind of out there."

Rancher Diana Souza says it would be a shame to stop public funding of stem cell research. Through trials at UC Davis Medical Center not financed by Prop. 71 money, she says stem cells helped restore full use of her severely fractured arm.

"I hope they can continue doing this because it is a miracle. It does work. And I have a good arm to prove it," said Souza.

LOS ANGELES, Calif. - The creation of California's stem cell agency in 2004 was greeted by scientists and patients as a turning point in a field mired in debates about the destruction of embryos and hampered by federal research restrictions.

The taxpayer-funded institute wielded the extraordinary power to dole out $3 billion in bond proceeds to fund embryonic stem cell work with an eye toward treatments for a host of crippling diseases. Midway through its mission, with several high-tech labs constructed, but little to show on the medicine front beyond basic research, the California Institute for Regenerative Medicine faces an uncertain future.

Is it still relevant nearly eight years later? And will it still exist when the money dries up?

The answers could depend once again on voters and whether they're willing to extend the life of the agency.

Several camps that support stem cell research think taxpayers should not pay another cent given the state's budget woes.

"It would be so wrong to ask Californians to pony up more money," said Marcy Darnovsky of the Center for Genetics and Society, a pro-stem cell research group that opposed Proposition 71, the state ballot initiative that formed CIRM.

Last December, CIRM's former chairman, Robert Klein, who used his fortune and political connections to create Prop 71, floated the possibility of another referendum.

CIRM leaders have shelved the idea of going back to voters for now, but may consider it down the road. The institute recently submitted a transition plan to Gov. Jerry Brown and the Legislature that assumes it will no longer be taxpayer-supported after the bond money runs out. CIRM is exploring creating a non-profit version of itself and tapping other players to carry on its work.

"The goal is to keep the momentum going," board Chairman Jonathan Thomas said in an interview.

So far, CIRM has spent some $1.3 billion on infrastructure and research. At the current pace, it will earmark the last grants in 2016 or 2017. Since most are multi-year awards, it is expected to stay in business until 2021.

Several camps that support stem cell research think taxpayers should not pay another cent given the state's budget woes.

"It would be so wrong to ask Californians to pony up more money," said Marcy Darnovsky of the Center for Genetics and Society, a pro-stem cell research group that opposed Proposition 71, the state ballot initiative that formed CIRM.

Last December, CIRM's former chairman, Robert Klein, who used his fortune and political connections to create Prop 71, floated the possibility of another referendum.

CIRM leaders have shelved the idea of going back to voters for now, but may consider it down the road. The institute recently submitted a transition plan to Gov. Jerry Brown and the Legislature that assumes it will no longer be taxpayer-supported after the bond money runs out. CIRM is exploring creating a nonprofit version of itself and tapping other players to carry on its work.

"The goal is to keep the momentum going," board Chairman Jonathan Thomas said in an interview.

So far, CIRM has spent some $1.3 billion on infrastructure and research. At the current pace, it will earmark the last grants in 2016 or 2017. Since most are multi-year awards, it is expected to stay in business until 2021.
