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?

Cover Story: The Most Vulnerable Patients
Problems during pregnancy burden too many newborns with lifelong disabilities. Researchers are finding clues to a safer nine months, and a brighter future.

Taming Fear, Rising Calm
A social conscience rooted in the Deep South moves Kerry Ressler, a psychiatrist and neuroscientist, to try to ease the consequences of inner city trauma.

Membrane Awakening
Researchers are taking a more holistic look at cell membranes and the proteins embedded in them—and the surprises keep coming.

Enhancing TA Performance
Instead of letting teaching assistants sink or swim, risking their failure and the ire of the undergrads, some schools are prescribing a class in how to teach before they get in front of a class.
