Stem cells

A route used by tumor cells to spread could be exploited to make stem cells for regenerative medicine and cancer therapies

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

New study shows that adult skin cells made to differentiate like embryonic stem cells may reverse neurological damage

Starving healthy cells helps to differentiate them from tumor cells, a trick that could make cancer treatments more effective

Treatment strengthened weak paws without causing cancer

Reverse-engineered human stem cells may leapfrog the embryonic kind

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?

New eye research center in India aims to fix visual impairments with the help of stem cells

Mouse finding hints that stemlike cells may yet be found in human pancreas

Deadly call and response recruits stem cells to nourish ticking tumors

Breakthrough could overcome key obstacle to embryonic stem cell research
