Repairing mutations in human mitochondria
LOS ANGELES Researchers at the UCLA stem cell center and the departments of chemistry and biochemistry and pathology and laboratory medicine have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases.
Mutations in the human mitochondrial genome are implicated in neuromuscular diseases, metabolic defects and aging. There currently are no methods to successfully repair or compensate for these mutations, said study co-senior author Dr. Michael Teitell, a professor of pathology and laboratory medicine and a researcher with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
Between 1,000 and 4,000 children per year in the United States are born with a mitochondrial disease and up to one in 4,000 children in the U.S. will develop a mitochondrial disease by the age of 10, according to Mito Action, a nonprofit organization supporting research into mitochondrial diseases. In adults, many diseases of aging have been associated with defects of mitochondrial function, including diabetes, Parkinson's disease, heart disease, stroke, Alzheimer's disease and cancer.
"I think this is a finding that could change the field," Teitell said. "We've been looking to do this for a long time and we had a very reasoned approach, but some key steps were missing. Now we have developed this method and the next step is to show that what we can do in human cell lines with mutant mitochondria can translate into animal models and, ultimately, into humans."
The study appears today in the peer-reviewed journal Proceedings of the National Academy of Sciences.
The current study builds on previous work published in 2010 in the peer-reviewed journal Cell, in which Teitell, Carla Koehler, a professor of chemistry and biochemistry and a Broad stem cell research center scientist, and their team uncovered a role for an essential protein that acts to shuttle RNA into the mitochondria, the energy-producing "power plant" of a cell.
Mitochondria are described as cellular power plants because they generate most of the energy supply within a cell. In addition to supplying energy, mitochondria also are involved in a broad range of other cellular processes including signaling, differentiation, death, control of the cell cycle and growth.
The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria have remained poorly understood.
The study in Cell outlined a new role for a protein called polynucleotide phosphorylase (PNPASE) in regulating the import of RNA into mitochondria. Reducing the expression or output of PNPASE decreased RNA import, which impaired the processing of mitochondrial genome-encoded RNAs. Reduced RNA processing inhibited the translation of proteins required to maintain the mitochondrial electron transport chain that consumes oxygen during cell respiration to produce energy. With reduced PNPASE, unprocessed mitochondrial-encoded RNAs accumulated, protein translation was inhibited and energy production was compromised, leading to stalled cell growth.
The findings from the current study provide a form of gene therapy for mitochondria by compensating for mutations that cause a wide range of diseases, said study co-senior author Koehler.

UCLA scientists find insulin, nutrition prevent blood stem cell differentiation in fruit flies
Public release date: 11-Mar-2012 [ | E-mail | Share ]

UCLA stem cell researchers have shown that insulin and nutrition keep blood stem cells from differentiating into mature blood cells in Drosophila, the common fruit fly, a finding that has implications for studying inflammatory response and blood development in response to dietary changes in humans.
Keeping blood stem cells, or progenitor cells, from differentiating into blood cells is important as they are needed to create the blood supply for the adult fruit fly.
The study found that the blood stem cells are receiving systemic signals from insulin and nutritional factors, in this case essential amino acids, that helped them to maintain their "stemness," said study senior author Utpal Banerjee, professor and chairman of the molecular, cell and developmental biology department in Life Sciences and a researcher with the Eli and Edythe Broad Center of Regenerative Medicine at UCLA.
"We expect that this study will promote further investigation of possible direct signal sensing mechanisms by mammalian blood stem cells," Banerjee said. "Such studies will probably yield insights into chronic inflammation and the myeloid cell accumulation seen in patients with type II diabetes and other metabolic disorders."
The study appears March 11, 2012 in the peer-reviewed journal Nature Cell Biology.
In the flies, the insulin signaling came from the brain, which is an organ similar to the human pancreas, which produces insulin. That insulin was taken up by the blood stem cells, as were amino acids found in the fly flood, said Ji Won Shim, a postdoctoral fellow in Banerjee's lab and first author of the study.
Shim studied the flies while in the larval stage of development. To see what would happen to the blood stem cells, Shim placed the larvae into a jar with no food - they usually eat yeast or cornmeal and left them for 24 hours. Afterward, she checked for the presence of blood stem cells using specific chemical markers that made them visible under a confocal microscope.
"Once the flies were starved and not receiving the insulin and nutritional signaling, all the blood stem cells were gone," Shim said. "All that were left were differentiated mature blood cells. This type of mechanism has not been identified in mammals or humans, and it will be intriguing to see if there are similar mechanisms at work there."

This type of mechanism has not been identified in mammals or humans, and it will be intriguing to see if there are similar mechanisms at work there.
In the fruit fly, the only mature blood cells present are myeloid cells, Shim said. Diabetic patients have many activated myeloid cells that could be causing disease symptoms. It may be that abnormal activation of myeloid cells and abnormal metabolism play a major role in diabetes.
Metabolic regulation and immune response are highly integrated in order to function properly dependent on each other. Type II diabetes and obesity, both metabolic diseases, are closely associated with chronic inflammation, which is induced by abnormal activation of blood cells, Shim said. However, no systemic study on a connection between blood stem cells and metabolic alterations had been done. Our study highlights the potential linkage between myeloid-lineage blood stem cells and metabolic disruptions.

Northwestern University scientists have developed a powerful analytical method that they have used to direct stem cell differentiation. Out of millions of possibilities, they rapidly identified the chemical and physical structures that can cue stem cells to become osteocytes, cells found in mature bone.
Researchers can use the method, called nanocombinatorics, to build enormous libraries of physical structures varying in size from a few nanometers to many micrometers for addressing problems within and outside biology.
Those in the fields of chemistry, materials engineering and nanotechnology could use this invaluable tool to assess which chemical and physical structures -- including size, shape and composition -- work best for a desired process or function.
Nanocombinatorics holds promise for screening catalysts for energy conversion, understanding properties conferred by nanostructures, identifying active molecules for drug discovery or even optimizing materials for tissue regeneration, among other applications.
Details of the method and proof of concept is published in the Proceedings of the National Academy of Sciences.
"With further development, researchers might be able to use this approach to prepare cells of any lineage on command," said Chad A. Mirkin, who led the work. "Insight into such a process is important for understanding cancer development and for developing novel cancer treatment methodologies."
Mirkin is the George B. Rathmann Professor of Chemistry in the Weinberg College of Arts and Sciences and professor of medicine, chemical and biological engineering, biomedical engineering and materials science and engineering. He also is the director of Northwestern's International Institute for Nanotechnology (IIN).
The new analytical method utilizes a technique invented at Northwestern called polymer pen lithography, where basically a rubber stamp having as many as 11 million sharp pyramids is mounted on a transparent glass backing and precisely controlled by an atomic force microscope to generate desired patterns on a surface. Each pyramid -- a polymeric pen -- is coated with molecules for a particular purpose.

Each pyramid -- a polymeric pen -- is coated with molecules for a particular purpose.
In this work, the researchers used molecules that bind proteins found in the natural cell environment, such as fibronectin, which could then be attached onto a substrate in various patterns. (Fibronectin is a protein that mediates cell adhesion.) The team rapidly prepared millions of textured features over a large area, which they call a library. The library consisted of approximately 10,000 fibronectin patterns having as many as 25 million features ranging in size from a couple hundred nanometers to several micrometers.
To make these surfaces, they intentionally tilt the stamp and its array of pens as the stamp is brought down onto the substrate, each pen delivering a spot of molecules that could then bind fibronectin. The tilt results in different amounts of pressure on the polymeric pens, which dictates the feature size of each spot. Because the pressure varies across a broad range, so does the feature size.

BioTime and Aastrom Biosciences -- Stem Cell Research Making Breakthroughs
Cell find boosts liver disease hope
Boosting the production of certain cells could help treat liver disease, new research has suggested.
Researchers at the Medical Research Council (MRC) Centre for Regenerative Medicine at the University of Edinburgh said they have discovered how to enhance the production of key cells needed to repair damaged liver tissue. The research could help develop treatments for diseases such as cirrhosis or chronic hepatitis.
Scientists hope their work could eventually ease the pressure on waiting lists for liver transplants. Researchers said that when the liver is damaged it produces too many bile duct cells and not enough cells called hepatocytes, which the liver needs to repair damaged tissue.
They found they could increase the number of hepatocyte cells - which detoxify the liver - by encouraging these cells to be produced instead of bile duct cells. Understanding how liver cells are formed could help to develop drugs to encourage the production of hepatocytes to repair liver tissue.
Professor Stuart Forbes, associate director at the MRC, who is a consultant hepatologist and was the academic leader of the study, said: "Liver disease is on the increase in the UK and is one of the top five killers. Increasing numbers of patients are in need of liver transplants, but the supply of donated organs is not keeping pace with the demand.
"If we can find ways to encourage the liver to heal itself then we could ease the pressure on waiting lists for liver transplants."
The production of hepatocyte cells was increased by altering the expression of certain genes in early stage liver cells. The university said that liver disease is the fifth biggest killer in the UK with almost 500 people waiting for a liver transplant, compared with just over 300 five years ago.
Dr Rob Buckle, head of regenerative medicine at the MRC, said: "Liver transplants have saved countless lives over the years, but demand will inevitably outstrip supply and in the long term we need to look beyond replacing damaged tissues to exploiting the regenerative potential of the human body.
"The MRC continues to invest heavily across the breadth of approaches that might deliver the promise of regenerative medicine, and this study opens up the possibility of applying our increasing knowledge of stem cell biology to stimulate the body's own dormant repair processes as a basis for future therapy."
The study is published in the journal Nature Medicine. It was carried out in collaboration with the University's MRC Centre for Inflammation Research, the Beatson Institute for Cancer Research in Glasgow and the KU Leuven in Belgium.

Cell find boosts liver disease hope
UCLA Scientists Identify Cell and Signaling Pathway that Regulates the Placental Blood Stem Cell Niche
Newswise UCLA stem cell researchers have discovered a critical placental niche cell and signaling pathway that prevent blood precursors from premature differentiation in the placenta, a process necessary for ensuring proper blood supply for an individuals lifetime.
The placental niche, a stem cell safe zone, supports blood stem cell generation and expansion without promoting differentiation into mature blood cells, allowing the establishment of a pool of precursor cells that provide blood cells for later fetal and post-natal life, said study senior author Dr. Hanna Mikkola, an associate professor of molecular cell and developmental biology and a researcher at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
Mikkola and her team found that PDGF-B signaling in trophoblasts, specialized cells of the placenta that facilitate embryo implantation and gas and nutrient exchanges between mother and fetus, is vital to maintaining the unique microenvironment needed for the blood precursors. When PDGF-B signaling is halted, the blood precursors differentiate prematurely, creating red blood cells in the placenta, Mikkola said.
The study, done in mouse models, appears March 1, 2012, in the peer-reviewed journal Developmental Cell.
We had previously discovered that the placenta provides a home for a large supply of blood stem cells that are maintained in an undifferentiated state. We now found that, by switching off one signaling pathway, the blood precursors in the placenta start to differentiate into red blood cells, Mikkola said. We learned that the trophoblasts act as powerful signaling centers that govern the niche safe zone.
The study found that the PDGF-B signaling in the trophoblasts is suppressing production of Erythropoietin (EPO), a cytokine that controls red blood cell differentiation.
When PDGF-B signaling is lost, excessive amounts of EPO are produced in the placenta, which triggers differentiation of red blood cells in the placental vasculature, said Akanksha Chhabra, study first author and a post-doctoral fellow in Mikkolas lab.
Mikkola and Chhabra used mouse models in which the placental structure was disrupted so they could observe what cells and signaling pathways were important components of the niche.
The idea was, if we mess up the home where the blood stem cells live, how do these cells respond to the altered environment, Chhabra said. We found that it was important to suppress EPO where blood stem cell expansion is desired and to restrict its expression to areas where red blood cell differentiation should occur.
The finding, Chhabra said, was exciting in that one single molecular change was enough to change the function of an important blood stem cell niche.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--
Advanced Cell Technology, Inc. (ACT, OTCBB: ACTC), a leader in the field of regenerative medicine, today announced year-end results for the year ended December 31, 2011. The Company utilized $13.6 million in cash for operations during the year, compared to $8.8 million in the year-earlier period. The increase in cash utilization resulted primarily from ACTs ongoing clinical activities in the US and Europe. ACT ended the year with cash and cash equivalents of $13.1 million, compared to $15.9 million in cash and cash equivalents in the year-earlier period.
Some of the 2011 highlights included:
2011 was a very important and successful year for ACT as we began our Phase 1/2 trials for the treatment of macular degeneration, said Gary Rabin, chairman and CEO of ACT. We are very excited about the preliminary Phase 1/2 clinical data from our dry-AMD and Stargardts disease trials, which were published in The Lancet earlier this year. The data demonstrated the safety of ACTs human embryonic stem cell (hESC)-derived retinal pigment epithelium (RPE) cells for the treatment of both diseases. The vision of both patients appears to have improved after transplantation, and no adverse safety issues have been observed. We look forward to validating these early findings as we expand these clinical activities throughout this year. Additionally, we made significant progress in advancing our scientific platform, expanding our board of directors and management team and strengthening our balance sheet.
The Company also announced today that it expects to shortly file a preliminary proxy statement with the Securities and Exchange Commission in which it will seek shareholder approval for a reverse split of between 1-for 20 and 1-for 80 shares. The Company is pursuing the reverse split for the sole purpose of meeting the requirements necessary for a listing on the Nasdaq Global Market. The Company believes that a listing on a national change will allow it to expand its shareholder base and improve the marketability of its common stock by attracting a broader range of investors.

A*STAR scientists make groundbreaking discovery on stem cell regulation
Public release date: 29-Feb-2012 [ | E-mail | Share ]
Contact: Ong Siok Ming ong_siok_ming@a-star.edu.sg 65-682-66254 Agency for Science, Technology and Research (A*STAR), Singapore
A*STAR scientists have for the first time, identified that precise regulation of polyamine levels is critical for embryonic stem cell (ESC) self-renewal the ability of ESCs to divide indefinitely and directed differentiation. This paper is crucial for better understanding of ESC regulation and was published in the journal Genes & Development on 1st March by the team of scientists from the Institute of Medical Biology (IMB), a research institute under the Agency for Science, Technology and Research (A*STAR).
Embryonic stem cells hold great potential for the development of cellular therapies, where stem cells are used to repair tissue damaged by disease or trauma. This is due to their unique ability to renew themselves and differentiate into any specific types of cell in the body. One of the challenges with cellular therapies is ensuring that ESCs are fully and efficiently differentiated into the correct cell type. This study sheds light on understanding how ESCs are regulated, which is essential to overcome these challenges and turn the vision of cell therapies into reality.
Using a mouse model, the team of scientists from IMB showed that high levels of Amd1 , a key enzyme in the polyamine synthesis pathway, is essential for maintenance of the ESC state and self renewal of ESCs. To further demonstrate the critical role of Amd1 in ESC self-renewal, the scientists showed that increasing Amd1 levels led to delayed ESC differentiation. The research also revealed that downregulation of Amd1 was necessary for differentiation of ESCs into neural precursor cells and that Amd1 is translationally regulated by a micro-RNA (miRNA), the first ever demonstration of miRNA-mediated regulation of the polyamine pathway.
While the polyamine pathway is well established and polyamines are known to be important in cancer and cell proliferation, their role in ESC regulation until now was unknown. This novel discovery, linking polyamine regulation to ESC biology, came about when the team set up a genome-wide screen to look for mRNAs under translational control in order to identify new regulators of ESC differentiation to neural precursor cells.
Dr Leah Vardy, Principle Investigator at the IMB and lead author of the paper, said, "The polyamines that Amd1 regulate have the potential to regulate many different aspects of self renewal and differentiation. The next step is to understand in more detail the molecular targets of these polyamines both in embryonic stem cells and cells differentiating to different cellular lineages. It is possible that manipulation of polyamine levels in embryonic stem cells through inhibitors or activators of the pathway could help direct the differentiation of embryonic stem cells to more clinically useful cell types."
Prof. Birgitte Lane, Executive Director of IMB, said, "This is a fine piece of fundamental research that will have breakthrough consequences in many areas and can bring about far-reaching applications. Developing cellular therapies is just one long-term clinical benefit of understanding ESC biology, which can also help develop stem cell systems for disease modeling, developing new drugs as well as a tool for researchers to answer other biological questions."

Women Can Make New Eggs After All, Stem-Cell Study Hints
Women may make new eggs throughout their reproductive yearschallenging a longstanding tenet that females are born with finite supplies, a new study says. The discovery may also lead to new avenues for improving women's health and fertility.
A woman has two ovaries, which release eggs during her monthly ovulation.(Learn more about the human body.)
Previous research had suggested that a woman is born with all the egg cells she will ever have in her lifetime.
But in recent experiments, scientists discovered a new type of stem cell in the ovaries thatwhen grown in the labgenerates immature egg cells.The same immature cells isolated from adult mouse ovaries canturn into fertile eggs.
Stem cells,found in embryos and certain adult body tissues, have the potential to grow into many different types of cells.
(See"Liposuction Fat Turned Into Stem Cells, Study Says.")
The finding reinforces the team's previous experiments in mice, which had identified a new type of ovarian stem cell that renews a female mouse's source of eggs throughout its fertile years.
That study, published in the journal Nature in 2004, was the "first to reach the conclusion that this long-held belief in our fieldthat young girls are given a bank account at birth that you can no longer deposit eggs to, just withdraw fromwas no longer true," said study leaderJonathan Tilly.
By reinforcing these earlier results in people, the new study is a "big step forward" from the mouse work, emphasized Tilly, director of the Vincent Center for Reproductive Biology at Massachusetts General Hospital in Boston.
From a purely biological perspective, the concept that a woman would continually generate new eggs during her reproductive years makes sensesince men constantly replenish their sperm, Tilly added. (Read how men produce 1,500 sperm a second.)

International Cellular Medicine Society Grants First Worldwide Accreditation to Tijuana Clinical Trial
Regenerative Medicine Institute, Mexico has been granted full accreditation for its clinical stem cell trials
Portland, Oregon (PRWEB) February 29, 2012
We are pleased that RMI undertook this process, says David Audley, executive director of the ICMS. The clinic understood that patient safety can only be assured through strict evaluation and rigorous oversight. From day one they have embraced the transparency that this program requires.
RMI is the first clinic to achieve this status under the ICMS Accreditation Program. The clinic has undergone two separate site audits as well as an institutional review board review evaluation. Most importantly, the clinic has placed in excess of 50 patients into the Treatment Registry for long-term outcome tracking. The safety profile has been excellent, continued Audley. We have tracked patients over at least two follow-ups and a minimum of six months and not seen a single cell-related adverse event.
The ICMS is currently evaluating nearly a dozen clinics worldwide. Accreditation is based upon the Guidelines for the Practice of Cell-Based Medicine developed and published by the ICMS. Key components of these guidelines are the ethical recruitment of patients, proper consent of patients and compliance with local laws and regulations in the treatment of patients.

International Cellular Medicine Society Grants First Worldwide Accreditation to Tijuana Clinical Trial
Stem-Cell Therapy Takes Off in Texas
By David Cyranoski of Nature magazine
With Texas pouring millions of dollars into developing adult stem-cell treatments, doctors there are already injecting paying customers with unproven preparations, supplied by an ambitious new company.
The US Food and Drug Administration (FDA) has not approved any such stem-cell treatment for routine clinical use, although it does sanction them for patients enrolled in registered clinical trials. Some advocates of the treatments argue, however, that preparations based on a patient's own cells should not be classed as drugs, and should not therefore fall under the FDA's jurisdiction.
There are certainly plenty of people eager to have the treatments. Texas governor Rick Perry, for instance, has had stem-cell injections to treat a back complaint, and has supported legislation to help create banks to store patients' harvested stem cells.
One company that has benefited from this buoyant climate is Celltex Therapeutics, which "multiplies and banks" stem cells derived from people's abdominal fat, according to chairman and chief executive David Eller. Its facility in Sugar Land, just outside Houston, opened in December 2011 and houses the largest stem-cell bank in the United States.
Celltex was founded by Eller and Stanley Jones, the orthopaedic surgeon who performed Perry's procedure, and it uses technology licensed from RNL Bio in Seoul. Because clinical use of adult-stem-cell treatments are illegal in South Korea, RNL has since 2006 sent more than 10,000 patients to clinics in Japan and China to receive injections.
Celltex says that although it processes and banks cells, it does not carry out stem-cell injections. It declined to answer Nature's questions about whether its cells have been used in patients. But there is evidence that the company is involved in the clinical use of the cells on US soil, which the FDA has viewed as illegal in other cases.
Public hype
In addition to the publicity surrounding Perry's treatment, a woman named Debbie Bertrand has been blogging about her experiences during a five-injection treatment with cells prepared at Celltex. Her blog (http://debbiebertrand.blogspot.com) hosts photographs of herself alongside Jones; Jennifer Novak, a Celltex nurse; Jeong Chan Ra, chief executive of RNL Bio; and her doctor, Jamshid Lotfi, a neurologist who works for the United Neurology clinic in Houston. Another photo is captioned: "My cells are being processed in here for my next infusion!!!" A third shows Bertrand, Lotfi and a physician called Matthew Daneshmand, who is, according to the caption, injecting Bertrand's stem cells into an intravenous drip, ready for the infusion. Nature has been unable to contact Bertrand.
Lotfi says that he has administered cells processed by Celltex to more than 20 people. "Five or six" -- including Bertrand -- have multiple sclerosis and "four or five" have Parkinson's disease, he says. Lotfi explains that patients sign up for treatment by contacting Novak, and that cells are prepared by removing about five grams of fat -- containing roughly 100,000 mesenchymal stem cells -- from the patient's abdomen. Over a three-week period, the cells are cultured until they reach about 800 million cells. Lotfi says that patients get at least three injections of 200 million cells each, and that the cells do not take effect for a few months. According to Lotfi, Celltex charges US$7,000 per 200 million cells, and pays Lotfi $500 per injection.
