Scientists prove that disputed Korean stem cell line comes from an unfertilized egg and not cloning
Can a genetic signature identify the origin of a human stem cell line? Scientists report that a widely available method for comprehensive genetic analysis can help distinguish the type of human embryo that stem cells come from. view more (2007-08-03)
Echoes of phlogiston in stem cell biology
Before it was learned that matter burns by taking up oxygen, most chemists sought to explain combustion as the release of a mysterious substance, which they named "phlogiston". view more (2009-09-22)
Dental stem cells have been characterized for tooth tissue engineering
Today, during the 84th General Session of the International Association for Dental Research, a team from The Forsyth Institute (Boston, MA, USA) will report that their research has demonstrated that mixed populations of cultured post-natal tooth bud cells can be used to generate bioengineered dental tissues. view more (2006-06-29)
Jefferson researchers find stem cells in degenerating spinal discs, potential for repair
Orthopedic researchers at Jefferson Medical College have for the first time found stem cells in the intervertebral discs of the human spine, suggesting that such cells might someday be used to help repair degenerating discs and remedy lower back and neck pain. view more (2007-11-01)
Master switches found for adult blood stem cells
Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state. view more (2007-02-12)
Human stem cell transplants mature into neurons and make contacts in rat spinal cord
Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won't allow nerve repair. view more (2007-02-14)
Cancer stem cells spur glioma Angiogenesis, could hold key to brain tumor therapy
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers. view more (2006-08-15)
Stem Cell Activity Deciphered in the Aging Brain
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial "progenitor" stem cells persist in the aging brain. view more (2006-12-19)
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...

Forsyth scientists trigger cancer-like response from embryonic stem cells
Scientists from The Forsyth Institute, working with collaborators at Tufts and Tuebingen Universities, have discovered a new control over embryonic stem cells' behavior. view more (2008-10-14)
Novel stem cell technology leads to better spinal cord repair
Researchers believe they have identified a new way, using an advance in stem-cell technology, to promote recovery after spinal cord injury of rats, according to a study published in today's Journal of Biology. view more (2006-04-28)
How embryonic stem cells maintain their identity
Two studies in the April 21, 2006 Cell report new details of the "genetic program" that affords embryonic stem cells the flexibility to give rise to any cell type in the body. view more (2006-04-21)
Building brains: Mammalian-like neurogenesis in fruit flies
A new way of generating brain cells has been uncovered in Drosophila. The findings, published this week in the online open access journal Neural Development, reveal that this novel mode of neurogenesis is very similar to that seen in mammalian brains, suggesting that key aspects of neural development could be shared by insects and mammals. view more (2008-02-19)
Stem cell therapy makes cloudy corneas clear, according to Pitt researchers
Stem cells collected from human corneas restore transparency and don't trigger a rejection response when injected into eyes that are scarred and hazy, according to experiments conducted in mice by researchers at the University of Pittsburgh School of Medicine. view more (2009-04-09)
Bones hold the key to blood renewal
Though we think of them as solid and permanent, our bones are actually constantly being rebuilt throughout our lives. A team of scientists at the Weizmann Institute of Science has now revealed how cells that work at remodeling the bones play a direct part in the ongoing renewal of another system — the blood. view more (2006-06-20)
Protein that controls hair growth also keeps stem cells slumbering
Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently. It was thought they did so to protect themselves from unnecessary wear and tear. view more (2008-01-25)

Neural Stem Cells Are Long-Lived
New studies in mice have shown that immature stem cells that proliferate to form brain tissues can function for at least a year - most of the life span of a mouse - and give rise to multiple types of neural cells, not just neurons. view more (2005-10-06)
U-M researchers identify stem cells in pancreatic cancer
University of Michigan Comprehensive Cancer Center researchers have discovered the small number of cells in pancreatic cancer that are capable of fueling the tumor's growth. The finding is the first identification of cancer stem cells in pancreatic tumors. view more (2007-02-01)
Scientists identify embryonic stem cells by appearance alone
Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait. view more (2007-08-28)
