Study Sheds Light on Bone Marrow Stem Cell Therapy for Pancreatic Recovery

Posted: October 3, 2012 at 9:12 pm

Newswise LOS ANGELES (Oct. 2, 2012) Researchers at Cedars-Sinais Maxine Dunitz Neurosurgical Institute have found that a blood vessel-building gene boosts the ability of human bone marrow stem cells to sustain pancreatic recovery in a laboratory mouse model of insulin-dependent diabetes.

The findings, published in a PLoS ONE article of the Public Library of Science, offer new insights on mechanisms involved in regeneration of insulin-producing cells and provide new evidence that a diabetics own bone marrow one day may be a source of treatment.

Scientists began studying bone marrow-derived stem cells for pancreatic regeneration a decade ago. Recent studies involving several pancreas-related genes and delivery methods transplantation into the organ or injection into the blood have shown that bone marrow stem cell therapy could reverse or improve diabetes in some laboratory mice. But little has been known about how stem cells affect beta cells pancreas cells that produce insulin or how scientists could promote sustained beta cell renewal and insulin production.

When the Cedars-Sinai researchers modified bone marrow stem cells to express a certain gene (vascular endothelial growth factor, or VEGF), pancreatic recovery was sustained as mouse pancreases were able to generate new beta cells. The VEGF-modified stem cells promoted growth of needed blood vessels and supported activation of genes involved in insulin production. Bone marrow stem cells modified with a different gene, PDX1, which is important in the development and maintenance of beta cells, resulted in temporary but not sustained beta cell recovery.

Our study is the first to show that VEGF contributes to revascularization and recovery after pancreatic injury. It demonstrates the possible clinical benefits of using bone marrow-derived stem cells, modified to express that gene, for the treatment of insulin-dependent diabetes, said John S. Yu, MD, professor and vice chair of the Department of Neurosurgery at Cedars-Sinai, senior author of the journal article.

Diabetes was reversed in five of nine mice treated with the injection of VEGF-modified cells, and near-normal blood sugar levels were maintained through the remainder of the six-week study period. The other four mice survived and gained weight, suggesting treatment was beneficial even when it did not prompt complete reversal. Lab studies later confirmed that genetically-modified cells survived and grew in the pancreas and supported the repopulation of blood vessels and beta cells.

Anna Milanesi, MD, PhD, working in Yus lab as an endocrinology fellow, is the articles first author. The researchers cautioned that although this and other related studies help scientists gain a better understanding of the processes and pathways involved in pancreatic regeneration, more research is needed before human clinical trials can begin.

Insulin-dependent diabetes occurs when beta cells of the pancreas fail to produce insulin, a hormone that regulates sugar in the blood. Patients must take insulin injections or consider transplantation of a whole pancreas or parts of the pancreas that make insulin, but transplantation carries the risk of cell rejection.

Sigma® Life Science Launches Novel, Affordable Pluripotent Stem Cell Culture Medium

Posted: October 3, 2012 at 4:12 pm

ST. LOUIS, Oct. 3, 2012 /PRNewswire/ --Sigma-Aldrich Corporation (SIAL) announced today that Sigma Life Science, its innovative biological products and services research business, has launched Stemline Pluripotent Culture Medium, a novel human pluripotent stem cell culture medium that provides a consistent environment for the long-term maintenance and growth of healthy pluripotent stem cells. The new medium performs equivalently to the industry's leading medium and provides academic and pharmaceutical stem cell research labs with a substantially lower cost alternative to higher priced media. Additional information and sample requests of the Stemline Pluripotent Culture Medium are available at http://www.sigma.com/stemlinepsc.

"The exorbitant cost of media for pluripotent stem cells is a universal complaint from the stem cell research community. Our Stemline Pluripotent Culture Medium performs equivalently to the leading medium for maintaining pluripotency and optimal growth rates, and is produced more efficiently than traditional media, resulting in lower costs. For example, a typical academic lab that consumes three 500 mL bottles of media per week could save at least $12,000 annually using our new Stemline medium. A high-throughput pharmaceutical development team that consumes 20 liters of media weekly could save more than $160,000 annually," said John Listello, Market Segment Manager for Regenerative Medicine at Sigma Life Science.

Culturing pluripotent stem cells can be challenging as many media's undefined, heterogenous mixtures can cause inconsistent growth rates and undesired spontaneous differentiation. The Stemline Pluripotent Stem Cell Culture Medium is serum-free, composed of fully-defined components and has 80% less basic fibroblast growth factor than the leading pluripotent stem cell culture medium. This provides a consistent environment for long-term maintenance of optimal growth rates, viability and pluripotency. Rigorous characterization of the Stemline Pluripotent Stem Cell Culture Medium has demonstrated that cultured pluripotent stem cells display all established pluripotency markers and maintain proper karyotype and the ability to differentiate into each of the three germ layers. The feeder-independent medium also enables culturing with synthetic matricies, thereby eliminating a source of variability that would prohibit later clinical applications.

"Academic and pharmaceutical groups performing toxicology screens, disease-specific stem cell research or studies of the basic mechanisms behind pluripotency and differentiation depend upon a steady supply of consistent, high-performance cell culture medium. This novel Stemline medium extends Sigma's existing position as one of the largest global providers of cell culture media," said Listello.

Existing Stemline stem cell culture media include specialized formulations for expansion of six human adult stem cell and progenitor cell types: hematopoietic, neural, dendritic, mesenchymal, T-cells, and keratinocytes. These six Stemline media are produced under good manufacturing practices (GMP) and have Device Master File certificates from the U.S. Food and Drug Administration.

Sigma Life Science's comprehensive stem cell product portfolio includes custom iPS cell CompoZr ZFN-mediated genetic engineering, Stemgent Reprogramming Lentiviruses, the MISSION shRNA Library with the latest content release from The RNAi Consortium, 3D matrices, growth factors, small molecules, other cell culture media and the industry's most validated antibodies. Sigma Life Science acquired a worldwide license to Kyoto University's iPS cell patent portfolio in February, 2012.

Seeing the study of stem cells

Posted: October 3, 2012 at 8:10 am

More than 200 high school students, including those in the Costa Mesa-based Coastline Regional Occupational Program, got an inside look at the stem cell research at UC Irvine.

UCI's Sue and Bill Gross Stem Cell Research Center opened its doors Monday for the first of several events to celebrate International Stem Cell Awareness Day, which is Wednesday. The university is also hosting a science symposium from 9 a.m. to 5 p.m. Wednesday with a Meet the Scientists interactive forum from 5 to 5:45 p.m.

"I think it is just an exciting time for this field, and what we want to do is get the word out," said Director Peter Donovan.

In a little more than decade, stem cells have moved from research to being used in humans, such a quick pace that people often compare it to the race to get a man on the moon, but stem cell research is moving much faster, Donovan said.

The speed partly comes from a feeling that the field can offer new treatment for diseases that have none, he said.

At UCI, about 200 scientists from graduate students to technicians to professors are studying stem cells and researching treatments for spinal cord and traumatic brain injuries, and diseases such as Alzheimer's and Huntington's.

"We truly believe that the work that we do here will transform the world," Donovan said.

UCI scientist Aileen Anderson gave students an overview of stem cells and explained her research, which led to the first human clinical trials of using neural stem cells to repair spinal cord injuries.

Anderson said understanding spinal cord injuries can have a broader impact on the research for a treatment in others areas, such as strokes, ALS and traumatic brain injuries.

"Stem cell research might be able to help a lot of different diseases," she said.

Adult stem cells change their epigenome to generate new organs

Posted: October 3, 2012 at 8:10 am

ScienceDaily (Oct. 2, 2012) The team led by Manel Esteller, director of the Cancer Epigenetics and Biology Program in the Bellvitge Biomedical Research Institute (IDIBELL), Professor of Genetics at the University of Barcelona and ICREA researcher, has identified epigenetic changes that occur in adult stem cells to generate different body tissues.

The finding is published this week in The American Journal of Pathology.

The genome of every single cell in the human body is the same, regardless of their appearance and function. Therefore the activity of the tissues and organs and its disorders in complex diseases, such as cancer, cannot be fully explained by the genome. It is necessary something more, and part of the explanation is provided by epigenetics, which is defined as "the inheritance of DNA activity that does not depend on strict sequence of it." That is, if genetics is the alphabet, spelling would be the epigenetics, which refers to chemical changes in our genetic material and their regulatory proteins. The most known epigenetic mark is the addition of a methyl group to DNA. Thus, the epigenome is getting all the epigenetic marks of a living being.

Adult stem cells have an enormous potential to regenerate damaged organs and their use also avoids ethical complications involving embryonic stem cells, as well as technical problems arising from induced stem cells. In this study, researchers have isolated stem cells from body fat and transformed them into muscle and bone cells. Then, it was necessary to know how much resembled are the cells created in the laboratory with those present in one individual and if they were biologically secured enough to be implanted in patients. The study shows that the epigenome of the cells obtained in culture closely resembles that of skeletal muscle cells and they are spontaneously present in nature, although not completely identical.

A key point of the study is that muscle and bone cells produced in the laboratory do not have the tumour epigenome derived from these tumour tissues (rhabdomyosarcoma and osteosarcoma, respectively) so they are safe from a biological perspective. The study coordinator, Manel Esteller, stresses that the research "demonstrates the usefulness of epigenetics in determining the degree of maturity and biosecurity of differentiated tissues used in regenerative medicine against different diseases."

Blind Mice Get Experimental Stem Cell Treatment For Blindness

Posted: October 3, 2012 at 8:10 am

April Flowers for redOrbit.com Your Universe Online

Columbia University ophthalmologists and stem cell researchers have developed an experimental treatment for blindness using the patients skin cells, which has improved the vision of blind mice in testing.

The findings of this research, published online in the journal Molecular Medicine, suggest that induced pluripotent stem cells (iPS) could soon be used to improve vision in people with macular degeneration and other eye retina diseases. iPS cells are derived from adult human skin cells but have embryonic qualities.

With eye diseases, I think were getting close to a scenario where a patients own skin cells are used to replace retina cells destroyed by disease or degeneration, says Stephen Tsang, MD, PhD, associate professor of ophthalmology and pathology & cell biology. Its often said that iPS transplantation will be important in the practice of medicine in some distant future, but our paper suggests the future is almost here.

Scientists were very excited by the advent of human iPS cells when they were discovered in 2007, as they provide a way to avoid the ethical complications of embryonic stem cells. Another advantage is that the iPS cells are created from the patients own skin, eliminating the need for anti-rejection medications. Like the ethically challenged embryonic cells, iPS cells can develop into any type of cell. To-date, no iPS cells have been implanted into people, but many ophthalmologists say that the eye would prove to be ideal testing ground for iPS therapies.

The eye is a transparent and accessible part of the central nervous system, and thats a big advantage. We can put cells into the eye and monitor them every day with routine non-invasive clinical exams, Tsang said. And in the event of serious complications, removing the eye is not a life-threatening event.

Professor Tsang is running a new preclinical iPS study using human iPS cells derived from the skin cells of a 53-year-old donor. The cells were first transformed with a cocktail of growth factors into cells in the retina that lie underneath the eyes light-sensing cells.

Retina cells nourish the light-sensing cells and protect the fragile cells from excess light, heat and cellular debris. In macular degeneration and retinitis pigmentosa, retina cells die, which allows the photoreceptor cells to degenerate causing the patient to lose their vision. It is estimated that 30 percent of people will have some form of macular degeneration by the time they are 75 years old, as it is the leading cause of vision loss in the elderly. Currently, it affects 7 million Americans and that is expected to double by 2020.

The Columbia research team injected the iPS-derived retina cells into the right eyes of 34 mice that had a genetic mutation that caused their retina cells to degenerate. In many of the mice, the iPS cells assimilated into the retina without disruption and functioned as normal retina cells well into the animals old age. Mice in the control group, who received injections of saline or inactive cells, showed no improvement in retina tests.

Our findings provide the first evidence of life-long neuronal recovery in a preclinical model of retinal degeneration, using stem cell transplant, with vision improvement persisting through the lifespan, Tsang says. And importantly, we saw no tumors in any of the mice, which should allay one of the biggest fears people have about stem cell transplants: that they will generate tumors.

Histogenics Honored as a 2012 “Fierce 15” Company by FierceMedicalDevices

Posted: October 2, 2012 at 8:14 pm

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

Histogenics, a regenerative medicine company combining cell therapy and tissue engineering technologies to develop highly innovative products for tissue repair and regeneration, announced today that it has been named to the FierceMedicalDevices Fierce 15 list, designating it as one of the leading medical device and diagnostic companies of 2012. FierceMedicalDevicesEditors Mark Hollmer and Damian Garde, in conjunction with Editor-in-Chief John Carroll and Executive Editor Ryan McBride, chose this years winners based on their top management teams, notable financial backing, and promising technologies and market opportunities.

We have worked hard over the past year, securing $49 million in financing and adding key new staff, investors and board members, so that we are now in the position to focus our full attention on continued successful clinical and regulatory execution for NeoCart cartilage regeneration implant, which is currently enrolling patients into the Phase 3 IND clinical study, and the EU regulatory development of our VeriCart cartilage repair scaffold, said Patrick ODonnell, President and Chief Executive Officer of Histogenics. We believe our product candidates have the potential to transform the treatment of cartilage injury with the goal of returning some of the estimated 1.8 million patients each year in the U.S. and E.U. that undergo arthroscopy for knee cartilage defects to their pre-injury level of activity.

Nailing down $49 million in financing in July reinforces the notion that this regenerative medicine company stands out for doing things differently.One example how: The company is well underway enrolling patients in a Phase 3 trial for NeoCart, a cartilage implant that uses a patients own cells to build it before treating cartilage lesions in the knee, said Hollmer.

NeoCart is an autologous neocartilage tissue implant in an ongoing Phase 3 clinical program that utilizes the patients own cells to regenerate cartilage in patients suffering from cartilage lesions in the knee.VeriCart, is a single-step, cell-free collagen scaffold uniquely designed to be used in conjunction with the patients own stem cells to repair small cartilage defects frequently observed in meniscal and anterior cruciate ligament repair procedures. Histogenics is seeking regulatory clearance in the European Union for VeriCart.
