New role found for a cardiac progenitor population (5/15/2008)

In a discovery that could one day lead to an understanding of how to regenerate damaged heart tissue, researchers have found that parent cells involved in embryonic development of the epicardium - the cell layer surrounding the outside of the heart - give rise to three important types of cells with potential for cardiac repair. ...> Full Article

Injection of human umbilical cord blood helps aging brain (3/12/2008)

When human umbilical cord blood cells were injected into aged laboratory animals, researchers found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells. ...> Full Article

Building Brains: Mammalian-like Neurogenesis In Fruit Flies (3/2/2008)

The nerve cells in the brain of Drosophila are generated by neural stem cell-like progenitor cells called neuroblasts. In the currently accepted model of neurogenesis, these neuroblast divide asymmetrically both to self renew and to produce a smaller progenitor cell. This smaller cell then divides only once into two daughter cells, which receive cell fate determinants, causing them to exit the cell cycle and differentiate into postmitotic neural cells. ...> Full Article

Adult stem cell application effective in treatment of peripheric vascular disease (1/24/2008)

Multipotent adult progenitor stem cells extracted from bone marrow, and known as MAPCs, have proved to be effective in the regeneration of blood vessel tissue and also in muscle tissue when treating peripheric vascular disease ...> Full Article

NYU Medical Center Awarded 1 Million Stem Cell Grant from New York State (1/13/2008)

NYU Medical Center has received a grant of $1 Million from the Empire State Stem Cell Board, which-established in 2007 by Governor Eliot Spitzer-announced its first awards today. The award will be used to supplement funding for work already underway in NYU School of Medicine's Helen and Martin Kimmel Center of Stem Cell Biology, as well as to acquire state-of-the art equipment and to create training programs to attract more researchers to the stem cell field. ...> Full Article

Researchers identify granddaddy of human blood cells (12/15/2007)

Researchers have isolated a human blood cell that represents the great-grandparent of all the cells of the blood, a finding that could lead to new treatments for blood cancers and other blood diseases. ...> Full Article

Imaging Neural Progenitor Cells In The Living Human Brain (11/18/2007)

For the first time, investigators have identified a way to detect neural progenitor cells (NPCs), which can develop into neurons and other nervous system cells, in the living human brain using a type of imaging called magnetic resonance spectroscopy (MRS). The finding may lead to improved diagnosis and treatment for depression, Parkinson's disease, brain tumors, and a host of other disorders. ...> Full Article

'Fingerprints' help find genes involved in differentiation (11/16/2007)

A database that includes the molecular profiles of the major components of the blood system – including the stem cells and the cells differentiated from them – enabled researchers at Baylor College of Medicine in Houston to identify at least two genes involved in the differentiation process for two different kinds of blood cells. ...> Full Article

Team of Scientists Develops Non-Invasive Method to Track Nerve-Cell Development in Live Human Brain (11/10/2007)

A team of scientists have identified and validated the first biomarker that permits neural stem and progenitor cells (NPCs) to be tracked, non-invasively, in the brains of living human subjects. This important advance could lead to significantly better diagnosis and monitoring of brain tumors and a range of serious neurological and psychiatric disorders. ...> Full Article

When Is A Stem Cell Not Really A Stem Cell? (8/28/2007)

Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between "true" neural stem cells and similar, but less potent versions. Their finding, reported in Nature, could simplify the isolation of stem cells not only from brain but also other body tissues. ...> Full Article

Progenitor Cell Acts Like Changeling to Become Whatever Cell Is Needed (7/13/2007)

Human development has long been seen as a one-way street. During gestation, stem cells were thought to develop into a succession of ever more specialized cells. As Dr. R. Ariel Gomez has discovered, the final identity of these cells is not as definite as once thought. "The identity of many cell types is in a constant state of flux," Gomez says. ...> Full Article

Researchers Identify Antioxidant Mechanisms Involved in Protection Against Cardiovascular Disease (5/4/2007)

Zvonimir Katusic, M.D., Ph.D., and Mayo colleagues have identified antioxidant mechanisms essential for regenerative function of endothelial progenitor cells (EPCs). ...> Full Article

Stem cell therapy shows promise for rescuing deteriorating vision (3/29/2007)

Building bone marrow with Stem Cells (3/20/2007)

A team of researchers from the University of Minnesota and Stanford University has found that a type of adult stem cell can replace the bone marrow and regenerate the immune systems of mice. If the finding can be extended to humans, it could mean a new and more abundant supply of cells for bone marrow transplant patients. ...> Full Article

Repairing Heart Damage caused by severe Coronary Artery Disease with Adult Stem Cells (2/5/2007)
