The following is an excerpt.
Stem cells, known for their ability to self-renew and differentiate into any kind of tissue, are considered by many scientists in the field to be immortal. But there are signs that programmed death of stem cells is important for their regulation.
New research from scientists at Rockefeller University and the Howard Hughes Medical Institute has identified a gene that plays a key role in regulating stem cell death, a finding that has major implications for regenerative medicine, wound healing and cancer.
