Stem Cells Apparently Repair Tissue

From Times Wire Reports May 12, 2007

Stem cells made from human embryos can home in on damaged eyes, hearts and arteries of mice and rats, and appear to start repairs, researchers report.

Writing in the journal Nature Methods on Monday, a group led by researchers from biotech company Advanced Cell Technology said they had devised a straightforward way to make blood vessel precursor cells out of the stem cells.

"When injected into the bloodstream, they homed to the other side of the body and repaired damaged vasculature within 24 to 48 hours," said Dr. Robert Lanza, vice president of research and scientific development at ACT.
