Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...tem cells are designed by nature to perform tissue repair in a mature adult. It is believed that these cells can be used in patients unrelated to the donor, without rejection, eliminating the need for donor matching and recipient immune suppression. Once transplanted, the cells promote healing of damaged or...

Researchers find molecular 'brake' to cell death

...die, or is initiated when a cell is damaged beyond repair or infected by a virus. Apoptosis is rare in cancer because tumor cells have adapted biological pathways to circumvent cell death, so many anti-cancer therapies focus on inducing apoptosis in these cells, Tang says.
