More than 900 Physicians Converge on Buenos Aires for Global Stem Cells Groups First International Symposium on Stem …

MIAMI (PRWEB) October 22, 2014

More than 900 physicians researchers and regenerative medicine experts from around the world attended the First International Symposium on Stem Cells and Regenerative Medicine, held in Buenos Aires, Argentina Oct. 2-4, 2014.

The event, hosted by Global Stem Cells Group in partnership with Julio Ferreira, M.D., President of the South American Academy Cosmetic Surgery, offered an opportunity for many of the worlds most respected authorities on stem cell and regenerative medicine to showcase advancements in research and therapies on a global level.

An interdisciplinary team of leading international stem cell experts provided a full day of high-level scientific lectures geared to medical professionals. Pioneers and luminaries in stem cell medicine who served as featured speakers at the event included:

Lord David Harrell, PhD., a scientific leader recognized nationally, internationally recognized expert in neuroscience and regenerative medicine and a member of the Global Stem Cells Group Advisory Board spoke on spoke on the cellular composition of bone marrow with a focus on stem and progenitor cell activities of bone marrow stem and progenitor cells.

Joseph Purita, M.D., Director of The Institute of Regenerative and Molecular Orthopedics in Boca Raton, Florida, member of the Global Stem Cells Group Advisory Board and a pioneer in the use of stem cells and platelet rich plasma for a variety of orthopedic conditions, spoke about the use of PRP and stem cell injections for treatment of musculoskeletal conditions. He detailed cutting-edge treatments he now offers to his clinic patients, including extensive use of platelet-rich plasma in conjunction with bone marrow stem cells (BMAC), adipose stem cells (SVF) and fat grafts.

Vasilis Paspaliaris, M.D., CEO of Adistem, Ltd., a member of the Global Stem Cells Group Advisory Board and a thought-leading and highly experienced clinical pharmacologist and medical scientist discussed the proven differences in efficacy between the mesenchyme stem cells (MSCs) of a young donor and those of an aging donor, primarily due to the younger donor cells ability to secrete more trophic factors.

According to Benito Novas, Global Stem Cells Group CEO, the world-class event was well received at a time when the field of regenerative medicine is on the verge of changing medical science forever.

We wanted the symposium to help clear up old misconceptions and change outdated attitudes by educating people on the wide range of illnesses and injuries stem cell therapies are already treating and curing, Novas says. We set out to establish a dialogue between researchers and practitioners in order to help move stem cell therapies from the lab to the physicians office and I believe we achieved our goals with this symposium.

Our objective is to open a dialogue among the worlds medical and scientific communities in order to advance stem cell technologies and translate them into point-of-care medical practices.

The New York Stem Cell Foundation Research Institute announces largest-ever stem cell repository

PUBLIC RELEASE DATE:

22-Oct-2014

Contact: David McKeon dmckeon@nyscf.org 212-365-7440 New York Stem Cell Foundation @nyscf

NEW YORK, NY (October 22, 2014) The New York Stem Cell Foundation (NYSCF) Research Institute, through the launch of its repository in 2015, will provide for the first time the largest-ever number of stem cell lines available to the scientific research community. Initially, over 600 induced pluripotent stem (iPS) cell lines and 1,000 cultured fibroblasts from over 1,000 unique human subjects will be made available, with an increasing number available in the first year. To collect these samples, NYSCF set up a rigorous human subjects system that protects patients and allows for the safe and anonymous collection of samples from people interested in participating in research.

A pilot of over 200 of NYSCF's iPS cell lines is already searchable on an online database. The pilot includes panels of iPS cell lines generated from donors affected by specific diseases such as type 1 diabetes, Parkinson's disease, and multiple sclerosis, as well as a diversity panel of presumed healthy donors from a wide range of genetic backgrounds representing the United States Census. These panels, curated to provide ideal initial cohorts for studying each area, include subjects ranging in age of disease onset, and are gender matched. Other panels that will be available in 2015 include Alzheimer's disease, schizophrenia, Juvenile Batten disease, and Charcot-Marie-Tooth disease.

"NYSCF's mission is to develop new treatments for patients. Building the necessary infrastructure and making resources available to scientists around the world to further everyone's research are critical steps in accomplishing this goal," said Susan L. Solomon, CEO of The New York Stem Cell Foundation.

NYSCF has developed the technology needed to create a large collection of stem cell lines representing the world's population. This platform, known as the NYSCF Global Stem Cell ArrayTM, is an automated robotic system for stem cell production and is capable of generating 200 iPS cell lines a month from patients with various diseases and conditions and from all genetic backgrounds. The NYSCF Global Stem Cell ArrayTM is also used for stem cell differentiation and drug screening.

Currently available in the online database that was developed in collaboration with eagle-i Network, of the Harvard Catalyst, is a pilot set of approximately 200 iPS cell lines and related information about the patients. This open source, open access resource discovery platform makes the cell lines and related information available to the public on a user-friendly, web-based, searchable system. This is one example of NYSCF's efforts to reduce duplicative research and enable even broader collaborative research efforts via data sharing and analysis. NYSCF continues to play a key role in connecting the dots between patients, scientists, funders, and outside researchers that all need access to biological samples.

"The NYSCF repository will be a critical complement to other existing efforts which are limited in their ability to distribute on a global scale. I believe that this NYSCF effort wholly supported by philanthropy will help accelerate the use of iPS cell based technology," said Dr. Mahendra Rao, NYSCF Vice President of Regenerative Medicine.

To develop these resources, NYSCF has partnered with over 50 disease foundations, academic institutions, pharmaceutical companies, and government entities, including the Parkinson's Progression Markers Initiative (PPMI), PersonalGenomes.org, the Beyond Batten Disease Foundation, among several others. NYSCF also participates in and drives a number of large-scale multi stakeholder initiatives including government and international efforts. One such example is the Cure Alzheimer's Fund Stem Cell Consortium, a group consisting of six institutions, including NYSCF, directly investigating, for the first time, brain cells in petri dishes from individual patients who have the common sporadic form of Alzheimer's disease.

Human Skin Cells Reprogrammed Directly Into Brain Cells

Contact Information

Available for logged-in reporters only

Newswise Scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntingtons disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types, the studys authors report.

The researchers, at Washington University School of Medicine in St. Louis, demonstrated that these converted cells survived at least six months after injection into the brains of mice and behaved similarly to native cells in the brain.

Not only did these transplanted cells survive in the mouse brain, they showed functional properties similar to those of native cells, said senior author Andrew S. Yoo, PhD, assistant professor of developmental biology. These cells are known to extend projections into certain brain regions. And we found the human transplanted cells also connected to these distant targets in the mouse brain. Thats a landmark point about this paper.

The work appears Oct. 22 in the journal Neuron.

The investigators produced a specific type of brain cell called medium spiny neurons, which are important for controlling movement. They are the primary cells affected in Huntingtons disease, an inherited genetic disorder that causes involuntary muscle movements and cognitive decline usually beginning in middle-adulthood. Patients with the condition live about 20 years following the onset of symptoms, which steadily worsen over time.

The research involved adult human skin cells, rather than more commonly studied mouse cells or even human cells at an earlier stage of development. In regard to potential future therapies, the ability to convert adult human cells presents the possibility of using a patients own skin cells, which are easily accessible and wont be rejected by the immune system.

To reprogram these cells, Yoo and his colleagues put the skin cells in an environment that closely mimics the environment of brain cells. They knew from past work that exposure to two small molecules of RNA, a close chemical cousin of DNA, could turn skin cells into a mix of different types of neurons.

In a skin cell, the DNA instructions for how to be a brain cell, or any other type of cell, is neatly packed away, unused. In past research published in Nature, Yoo and his colleagues showed that exposure to two microRNAs called miR-9 and miR-124 altered the machinery that governs packaging of DNA. Though the investigators still are unraveling the details of this complex process, these microRNAs appear to be opening up the tightly packaged sections of DNA important for brain cells, allowing expression of genes governing development and function of neurons.

Japanese researchers create cardiac tissue sheet with vascular cells from iPS

A team of Japanese researchers has successfully created cardiac tissue sheets generated from human induced pluripotent stem cells, according to a study published in the online British journal Scientific Reports.

The team said it is the first time iPS cells have produced an integrated cardiac tissue sheet that includes vascular cells as well as cardiac muscle cells and is close to real tissue in structure.

The stem cell researchers, led by Kyoto University professor Jun Yamashita, hopes its achievement may contribute to treatments for heart disease, as it has already found evidence that transplanting the sheets into mice with failing hearts improves in their cardiac condition.

The team used a protein called VEGF, which is related to the growth of blood vessels, as a replacement for the Dkk1 protein previously used to create cardiac muscle sheets from iPS cells.

As a result, iPS cells were simultaneously differentiated to become cardiac muscle cells, vascular mural cells, and the endothelial cells which line the interior surface of blood vessels. The cells were cultivated into a sheet about 1 cm in diameter.

Three-layer cardiac tissue sheets were then transplanted into nine mice with dead or damaged heart muscle due to cardiac infarction. In four of the mice, blood vessels formed in the area where the sheets were transplanted, leading to improved cardiac functioning.

The weak point of iPS cells is that there is a risk of developing cancer, but the cells did not become cancerous within two months of transplantation, the team said.

About 72 percent of the cardiac tissue sheet was made of cardiac muscle cells, while 26 percent consisted of endothelial cells and vascular mural cells. But the sheet contained a small portion of cells that had not changed, leading the team to call attention to the possibility of a cancerous change over the longer term.

Yamashita said in the study that he believed the cardiac sheets attached well.

Oxygen and nourishment were able to reach cardiac muscle through blood because there were blood vessels, he said.

University Of Pennsylvania's T-Cell Therapy Shows Promising Results

By C. Rajan, contributing writer

The University of Pennsylvania has announced promising results of its novel chimeric antigen receptor (CAR) therapy for cancer.

In the study involving 25 children and five adults with end-stage acute lymphoblastic leukemia (ALL), there was an impressive 90 percent response rate with complete remission.

Twenty-seven of the 30 patients went into complete remission after receiving the investigational therapy (called CTL019), and 78 percent of the patients were alive six months after treatment. The longest remission among the patients has lasted almost three years.

The patients who participated in these trials had relapsed as many as four times, including 60 percent whose cancers came back even after stem cell transplants. Their cancers were so aggressive they had no treatment options left, said the studys senior author, Stephan Grupp, MD, PhD, at the Children's Hospital of Philadelphia. The durable responses we have observed with CTL019 therapy are unprecedented.

The ongoing study is being conducted by researchers at the Childrens Hospital of Philadelphia and the Hospital of the University of Pennsylvania (Penn). The CAR trial program enrolling children with leukemia is also expanding to nine other pediatric centers.

The experimental CAR therapy received FDAs breakthrough designation in July for the treatment of relapsed and refractory adult and pediatric ALL. The novel treatment was pioneered by Penn researchers and then supported by Novartis. Penn entered an exclusive global research and licensing agreement with Novartis in 2012 to develop and commercialize personalized CAR T-cell therapies for cancers.

"This represents a really powerful therapy for ALL," Penn oncologist David Porter says. "We've treated enough patients to confirm that. It's time to start multi-center trials."

A CAR is a genetically engineered marker protein that is grafted onto T cells, which are part of the immune system. The CAR activates the T cell to attack tumor cells that express specific markers; in this case, the target is a protein called CD19.

The treatment procedure involves removing patients' T cells via an apheresis process and then genetically reprogramming them to hunt tumor cells. When injected back into patients bodies, these new hunter cells multiply and attack tumor cells expressing CD19. The hunter cells can grow, creating 10,000+ new cells in the body for each single engineered cell injected into the patients.

Maynooth University research team involved in evolution breakthrough

Sully Vent in the Main Endeavour Vent Field, NE Pacific

Evolutionary leaps in the world of microorganisms have resulted in dramatic changes in how life on the planet evolved, according to recent breakthrough research conducted by a team of researchers from Maynooth University andscientists from Germany and New Zealand.

The research, which has just been published in the journal Nature,analyses horizontal gene transfer (HGT), the phenomenon whereby prokaryotes (tiny cells that lack a cell nucleus) transfer genetic material far across their species boundaries, taking ownership of neighbouring genes and transferring them into their offspring. Over time, this transforms one microbial species into another, a process which in nature is similar to artificial genetic modification carried out in controlled laboratory settings.

Although scientists have known about HGT since the middle of the last century, until recently biologists thought HGT was limited to special categories of highly selected genes, such as those for antibiotic resistance. However, thisnew research has found that HGT is a major force in the evolution of life, and transformed many major groups of archaebacterial, the most primitive microbes known. The research proposes thatevolution occurred by sudden leaps and bounds, with whole genes for new traits changing hands, not just point mutations.

Discussing his teams research,Professor James McInerney, an evolutionary biologist atMaynooth University Department of Biology, said we are constantly learning more about the evolution of life on Earth. We have known about HGT for many years, hesaid.

However, the closer we look, the more of it we see. We are ata tipping point in our understanding of evolution, where the old idea that vertical transmission of DNA from ancestors to direct descendants is giving way to a viewpoint that, among microbes, horizontal transfers of DNA are just as important.

We are not saying that the previous picture of evolution is not true, simply that it did not give enough credit to a particular evolutionary mechanism and our study shows that this mechanism is hugely important. Had Darwin known about the curious patterns of characters that microbes share across broad taxonomic boundaries, he surely would have been relieved that HGT was responsible, and that his theory is alive and well today, but with new twists among microbes.

Our work is not the first to show that HGT has happened during the evolution of organisms, butit shows that an enormous group of microorganisms owe a significant amount of their uniqueness to this process,Professor McInerney said.

The team used extensive computer clusters to study the evolutionary history of the genes of archaea. The sequences of these genes can be compared with all other life forms and the evolutionary relationships for each gene were worked out based on the sequences. The research showed that significant numbers of genes were not native to the archaea studied, but rather those genes were acquired at specific time points during microbial evolution. The team found that for microscopic life HGT is more important than point mutation in generating diversity within and between populations. The events that the researchers identified entail, in some case, hundreds of genes at once hopping from one species to another.

Expert recommendations for diagnosing pediatric acute onset neuropsychiatric syndrome

PUBLIC RELEASE DATE:

22-Oct-2014

Contact: Kathryn Ryan kryan@liebertpub.com 914-740-2100 Mary Ann Liebert, Inc./Genetic Engineering News @LiebertOnline

New Rochelle, NY, October 22, 2014A panel of leading clinicians and researchers across various general and specialty pediatric fields developed a consensus statement recommending how to evaluate youngsters in whom neuropsychiatric symptoms suddenly develop, including the abrupt, dramatic onset of obsessive-compulsive disorder (OCD). This difficult diagnosis is typically made by pediatricians or other primary care clinicians and child psychiatrists, who will benefit from the guidance provided in the recommendations published in Journal of Child and Adolescent Psychopharmacology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article, part of a forthcoming special issue on PANS/PANDAS, is available free on the Journal of Child and Adolescent Psychopharmacology website until November 22, 2014.

Representing the PANS Collaborative Consortium, Kiki Chang, MD, Stanford University School of Medicine (Stanford, CA) and coauthors describe the goals of the First PANS Consensus Conference, from which the expert panel derived its recommendations: to clarify the diagnostic boundaries of PANS, to develop systematic strategies for evaluation of suspected PANS cases, and to set forth the most urgently needed studies in the field. Most cases of PANS appear to be triggered by an infection, and most often an upper respiratory infection.

In the article "Clinical Evaluation of Youth with Pediatric Acute Onset Neuropsychiatric Syndrome (PANS): Recommendations from the 2013 PANS Consensus Conference," the authors detail the core components of a thorough diagnostic evaluation, including family history, medical history, physical examination, psychiatric and mental status exam, laboratory studies, and an infectious disease evaluation.

"This is a watershed moment in our thinking about PANS," says Harold S. Koplewicz, MD, Editor-in-Chief of the Journal of Child and Adolescent Psychopharmacology and President of the Child Mind Institute in New York. "For too long confusion and a lack of understanding concerning this syndrome have left severely impaired children with few, if any, treatment options. This effort promises an improvement in the quality of care and we are grateful to be able support it and to publish our special issue on the topic."

Many Elderly Found with Puzzling Mutations Linked to Leukemia, Lymphoma

Researchers find no connection with blood cancer that seldom strikes senior citizens

Oct. 22, 2014 A surprisingly large percentage 5 percent of senior citizens over age 70 have been found to have genetic mutations linked to leukemia and lymphoma in their blood cells. The vast majority won't get blood cancer, however, as the incidence of these cancers is less than 0.1 percent among the elderly, according to the researchers at Washington University School of Medicine in St. Louis.

Mutations in the body's cells randomly accumulate as part of the aging process, and most are harmless. For some people, genetic changes in blood cells can develop in genes that play roles in initiating leukemia and lymphoma even though such people don't have the blood cancers, the scientists reported Oct. 19 in Nature Medicine.

"But it's quite striking how many people over age 70 have these mutations," said senior author Li Ding, PhD, of The Genome Institute at Washington University. "The power of this study lies in the large number of people we screened. We don't yet know whether having one of these mutations causes a higher than normal risk of developing blood cancers. More research would be required to better understand that risk."

The researchers analyzed blood samples from 3,000 people enrolled in The Cancer Genome Atlas project, a massive endeavor funded by the National Cancer Institute and the National Human Genome Research Institute at the National Institutes of Health (NIH). The effort involves cataloguing the genetic errors involved in more than 20 types of cancers.

The patients whose blood was analyzed for the current study had been diagnosed with cancer but were not known to have leukemia, lymphoma or a blood disease.

They ranged in age from 10 to 90 at the time of diagnosis and had donated blood and tumor samples before starting cancer treatment. Therefore, any mutations identified by the researchers would not have been associated with chemotherapy or radiation therapy, which can damage cells' DNA.

The researchers, including Genome Institute scientists Mingchao Xie, Charles Lu, PhD, and Jiayin Wang, PhD, zeroed in on mutations that were present in the blood but not in tumor samples from the same patients. Such genetic changes in the blood would be associated with changes in stem cells that develop into blood cells, but not to the same patient's cancer.

MPs to vote 'soon' on new gene therapy – pioneered by Newcastle University team

MPs will vote soon on a new gene therapy to stop incurable diseases passing to babies ending fears the Government is ducking the controversy.

The health minister threw her weight behind a DNA-altering procedure pioneered by a team at Newcastle University, saying: This is something I want to take forward.

Jane Ellison told a parliamentary inquiry: I am now actively seeking cross-Government approval for parliamentary time in this session to bring regulations before the House.

Im extremely conscious that there are real families waiting on progress on this work. We need to keep up the momentum.

The comments are a huge boost to the Newcastle team, which has called for legislation as soon as possible, because of the number of patients waiting for treatment.

Embryos are given healthy DNA from donor eggs, meaning a baby has the DNA of three people from two parents, plus less than one per cent from the donor.
