Studies indicate stem cells are flexible enough to become any cell in the body

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. Both groups identified mechanisms by which the embryonic stem cells of mice or humans keep from going down any one particular developmental path--that of muscle or nervous tissue, for example--while remaining "poised for activation."

The Notch effect steers stem cells into cells of the nervous system

Stem cell scientists at the University of Edinburgh have discovered that Notch, a protein first discovered more than 80 years ago in the fruit fly, directs unspecialized embryonic stem cells to become cells of the nervous system.

Single dose of stem cells produce robust behavioral recovery in animal models for stroke, cerebral palsy

A single dose of adult donor stem cells given to animals that have neurological damage similar to that experienced by adults with a stroke or newborns with cerebral palsy can significantly enhance recovery from these types of injuries, researchers say.

Australian stem cell breakthrough

A University of New South Wales (UNSW) researcher based at the Diabetes Transplant Unit (DTU) at Sydney's Prince of Wales Hospital has produced a human embryonic stem cell (hESC) line without the use of any animal products. The breakthrough eliminates the risk of animal-to-human contamination in potential stem cell therapy treatments.

Cloned stem cells are perfectly normal

Scientists generally agree that all cloned animals are biologically flawed. But they don't agree about what that means for stem cells derived from cloned embryos, the basis for therapeutic cloning.
