Critical Stem Cell Survival Factors Found
(01.25.07)
As researchers attempt to take advantage of the potential of adult stem cells in regenerative medicine, understanding the mechanisms that delimit lifespan and longevity of stem cells will be critically important.

Key Molecule Puts the Brakes on Stem-Cell Differentiation
(06.30.06)
Howard Hughes Medical Institute researchers have identified a protein that could aid development of methods to grow new skin to treat patients with burns or skin ulcers.

Researchers Map Protein Network That Regulates "Stemness"
(11.08.06)
Howard Hughes Medical Institute (HHMI) researchers have created a map that charts the largely unexplored protein landscape that regulates a stem cell's ability to differentiate into multiple types of mature cells.

From Sperm to Stem
(February 2008)
Adult stem cells derived from mouse testes appear to match the capabilities of embryonic stem cells

Sources of Renewal
(May 2008)
As scientists learn how to produce and manipulate stem cells—amid high expectations and close scrutiny—no one is ready to choose any one approach over the other.

Regeneration for Repair's Sake
(August 2007)
If a salamander can regrow a lost limb, why can't we? Or should we be aiming for a different goal?
