GUMC Researchers Show Adult Human Testes Cells Can Become Embryonic Stem-like, Capable of Treating Disease
Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from adult testes and have converted them back into pluripotent embryonic-like stem cells. Researchers say that the naïve cells are now potentially capable of morphing into any cell type that a body needs, from... view more... (2009-03-24)
Protein is Key to Embryonic Stem Cell Differentiation
Investigators at Burnham Institute for Medical Research (Burnham) have learned that a protein called Shp2 plays a critical role in the pathways that control decisions for differentiation or self-renewal in both human embryonic stem cells (hESCs) and mouse embryonic stem cells (mESCs). view more (2009-03-19)
Potential pathway for drug intervention
A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies. view more (2009-03-16)
Multiple route bone marrow stem cell injections show promise to treat spinal cord injury
Researchers from DaVinci Biosciences, Costa Mesa, California, in collaboration with Hospital Luis Vernaza in Ecuador, have determined that injecting a patient's own bone marrow-derived stem cells (autologous BMCs) directly into the spinal column using multiple routes can be an effective treatment for spinal cord injury (SCI) that returns some... view more...

Stem cell infusion and hyperbaric oxygen treatment improve islet function in diabetes
A study to determine if patients with type 2 diabetes can benefit from a combination of autologous (patient self-donated) stem cell infusions (ASC) and hyperbaric (above the normal air pressure of ) oxygen treatment (HBO) before and after ASC has found "significant benefits" in terms of "improvements in glycemic control" along... view more...

Well-known enzyme is unexpected contributor to brain growth
An enzyme researchers have studied for years because of its potential connections to cancer, diabetes, heart disease, hypertension and stroke, appears to have yet another major role to play: helping create and maintain the brain. view more (2009-03-12)
Iron induces death in tumor cells
Rapid growth of cancer cells and their frequent divisions have their price: Cancer cells need considerably more energy than healthy cells. view more (2009-03-11)
'Seeing' stem cells helps in fight against peripheral arterial disease
Interventional radiologists are fitting together the puzzle pieces of how to use stem cells to create new or more blood vessels to treat peripheral arterial disease (PAD) in those individuals with extensively narrowed or clogged arteries. view more (2009-03-10)
Seaweed and fireflies brew may guide stem cell treatment for peripheral artery disease
An unlikely brew of seaweed and glow-in-the-dark biochemical agents may hold the key to the safe use of transplanted stem cells to treat patients with severe peripheral arterial disease (PAD), according to a team of veterinarians, basic scientists and interventional radiologists at Johns Hopkins. view more (2009-03-10)
Survey: Few physicians support private banking of umbilical cord blood
A survey of physicians has found broad support for the position that parents should not bank their newborns' umbilical cord blood in a private blood bank unless another member of the family is at risk for a blood disease that will require a stem cell transplant. view more (2009-03-09)
Penn Veterinary Researchers Identify a Critical Growth Factor That Stimulates Sperm Stem Cells to Thrive
Researchers at the University of Pennsylvania School of Veterinary Medicine and Pennsylvania State University have identified for the first time a specific "niche factor" in the mouse testes called colony stimulating factor 1, Csf1, that has a direct effect on sperm stem cell self-renewal. view more (2009-03-09)
What is the role of the omentum in regenerating the liver?
In their recent work to be published on March 7, 2009 in the World Journal of Gastroenterology, Dr. Singh and his colleagues from the Cook County Hospital in Chicago (USA) first activated the omentum using a foreign body to increase its content of stem cells and growth factors and then used the activated omentum to regenerate the liver. view more (2009-03-09)
Stem cells replace stroke-damaged tissue in rats
Effective stem cell treatment for strokes has taken a significant step forward today (09 March) as scientists reveal how they have replaced stroke-damaged brain tissue in rats. view more (2009-03-09)
CU-Boulder research team identifies stem cells that repair injured muscles
A University of Colorado at Boulder research team has identified a type of skeletal muscle stem cell that contributes to the repair of damaged muscles in mice, which could have important implications in the treatment of injured, diseased or aging muscle tissue in humans, including the ravages of muscular dystrophy. view more (2009-03-06)
A New Way to Assemble Cells into 3-D Microtissues
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory can now control how cells connect with one another in vitro and assemble themselves into three-dimensional, multicellular microtissues. The researchers demonstrated their method by constructing a tailor-made artificial cell-signaling system, analogous to natural... view more... (2009-03-06)
Stem cells could halt osteoporosis, promote bone growth
While interferon gamma sounds like an outer space weapon, it's actually a hormone produced by our own bodies, and it holds great promise to repair bones affected by osteoporosis. view more (2009-03-05)
Assembling cells into artificial 3-D microtissues, including a tiny gland
