(June 26 , 2012) Researchers in Japan who evaluated the risks and efficacy of transplanting two varieties of stem cells into mouse cochlea have concluded that both adult-derived induced pluripotent stem (iPS) cells and mouse embryonic stem (ES) cells demonstrate similar survival and neural differentiation capabilities. However, there is a risk of tumor growth associated with transplanting iPS cells into mouse cochleae. Given the potential for tumorigenesis, they concluded that the source of iPS cells is a critical issue for iPS cell-based therapy. Their study is published in a recent issue of Cell Transplantation (21:4), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/, "Hearing loss affects millions of people worldwide," said Dr. Takayuki Nakagawa of the Department of Otolaryngology, Graduate School of Medicine, Kyoto University, Japan. "Recent studies have indicated the potential of stem-cell based approaches for the regeneration of hair cells and associated auditory primary neurons. These structures are essential for hearing and defects result in profound hearing loss and deafness." The authors noted that embryonic stem cells have previously been identified as promising … Continue reading →

The Sugar Land company involved in Gov. Rick Perry's unlicensed adult stem-cell procedure is rife with basic manufacturing problems, according to the U.S. Food and Drug Administration. In a report one expert called a blow to the entire adult stem-cell industry, the FDA found that Celltex Therapeutics Corp. cannot guarantee the sterility, uniformity and integrity of stem cells it takes from people and then stores and grows for eventual therapeutic reinjection. "You have not performed a validation of your banking and thawing process to assure viability" of the stem cells, reads the April 27 report, meaning that the company cannot verify the cells are alive. The FDA report, which followed an April 16-27 inspection of Celltex, was released under the Freedom of Information Act Monday to the Houston Chronicle and a University of Minnesota bioethicist who complained in February that Celltex is a potential danger to patients and not in compliance with federal law. The report, partially redacted, was not accompanied by a warning letter. A former FDA official who asked not to be identified, however, said the deficiencies - 79 in all, from incorrectly labeled products to failed sterility tests - are so serious that Celltex risks being shut … Continue reading →

Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells. The study is published in a recent issue of Cell Transplantation (21:4), now freely available online. "Cell therapy is a promising approach to myocardial regeneration and neovascularization, but currently suffers from the inefficient homing of cells after intracavitary infusion," said Dr. Philippe Menasche of the INSERM U633 Laboratory of Surgical Research in Paris. "Our study was aimed at improving and controlling homing by loading human cord-blood-derived endothelial progenitor cells (EPCs) for transplant with iron oxide nanoparticles in order to better position and retain them in the hearts of myocardial-injured test rats by using a subcutaneously implanted magnet." The researchers found that the cells were sufficiently magnetic to be able to be remotely manipulated by a magnet subsequent to implantation. According to the researchers, an objective assessment of the technique to enhance the homing of circulating stem cells is the ability to track … Continue reading →

COLORADO SPRINGS, Colo.--(BUSINESS WIRE)-- HemoGenix announced today that FDA CBER has given HemoGenix its first Master File Number for an in vitro blood stem cell potency, quality and release assay (HALO-96 PQR) (1)for cellular therapy products(2)used for stem cell transplantation purposes. HALO-96 PQR is the first commercially available stem cell potency assay for cellular therapy products. It incorporates the most sensitive readout available to measure changes in the cells energy source (ATP) as a function of the potential for stem cells to proliferate. Potency and quality of stem cell therapeutic products are required to be measured prior to use to help predict the engraftment of the cells in the patient. At the present time, tests such as cell number, viability and a stem cell marker called CD34 are routinely used. However, none of these tests specifically measure stem cells and none determine the stem cell biological activity required for a potency assay. The only cell functionality test presently used in this field, especially for umbilical cord blood transplantation, is the colony-forming unit (CFU) assay, which is subjective, non-validated and has been used since the early 1970s. HALO-96 PQR changes this paradigm. It is particularly needed in the umbilical cord blood … Continue reading →

BOSTON, MA--(Marketwire -06/25/12)- When it comes to disease, few are crueler than ALS. Approximately 5,600 people in the U.S. are diagnosed with ALS each year. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. The motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. The life expectancy is 2-5 years from the time of diagnosis. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. Most ALS patients expire from suffocation while suffering no cognitive depreciation. Brainstorm Cell Therapeutics Inc., trading on the Over the Counter Bulletin Board in the United States, is leading the fight to finding a cure for ALS with its NurOwn proprietary technology. The NurOwn technology is changing the field of regenerative medicine by reprogramming bone marrow derived from mesenchymal stem cells into neuron-supporting cells. The axon terminals (nerve cells ending) will take up neurotrophic factors secreted by the transplanted cells into the muscles or the spinal cord and transport them … Continue reading →

Reported in CELL, Stony Brook pathologist uncovers new p53 mechanism triggering necrosis Newswise STONY BROOK, N.Y., June 22, 2012 The gene p53 is the most commonly mutated gene in cancer. p53 is dubbed the guardian of the genome because it blocks cells with damaged DNA from propagating and eventually becoming cancerous. However, new research led by Ute M. Moll, M.D., Professor of Pathology at Stony Brook University School of Medicine, and colleagues, uncovers a novel role for p53 beyond cancer in the development of ischemic stroke. The research team identified an unexpected critical function of p53 in activating necrosis, an irreversible form of tissue death, triggered during oxidative stress and ischemia. The findings are detailed online in Cell. Ischemia-associated oxidative damage leads to irreversible necrosis which is a major cause of catastrophic tissue loss. Elucidating its signaling mechanism is of paramount importance. p53 is a central cellular stress sensor that responds to multiple insults including oxidative stress and is known to orchestrate apoptotic and autophagic types of cell death. However, it was previously unknown whether p53 can also activate oxidative stress-induced necrosis, a regulated form of cell death that depends on the mitochondrial permeability transition pore (PTP) pore. We identified … Continue reading →
