How Cells Clean House
Worn-out proteins, malfunctioning organelles, invading microorganisms: all are swept up by tiny internal "vacuum cleaners" that keep a living cell healthy. If the process, called autophagy, can be kept in good working order, aging itself might be delayed


Researchers Flesh Out Parkinson's Treatment Using Skin Cells
New study shows that adult skin cells made to differentiate like embryonic stem cells may reverse neurological damage

Fasting May Bolster Healthy Cells' Resistance to Chemo Toxins
Starving healthy cells helps to differentiate them from tumor cells, a trick that could make cancer treatments more effective

Human Embryonic Stem Cells Fix Stroke-Afflicted Rats
Treatment strengthened weak paws without causing cancer

Your Cells Are My Cells
Many, perhaps all, people harbor a small number of cells from genetically different individuals--from their mothers and, for women who have been pregnant, from their children. What in the world do these foreigners do in the body?

Potent Alternative
Reverse-engineered human stem cells may leapfrog the embryonic kind

A Visionary Approach Using Stem Cells to Repair Eye Damage
New eye research center in India aims to fix visual impairments with the help of stem cells

Elusive Pancreas-Healing Cells Discovered
Mouse finding hints that stemlike cells may yet be found in human pancreas

Tumor Time Bombs Set Off by Stem Cells
Deadly call and response recruits stem cells to nourish ticking tumors

Embryos Survive Stem Cell Harvest
Breakthrough could overcome key obstacle to embryonic stem cell research
