Stem cells to build blood vessels

Filed in archive Investigational on August 5, 2005

A novel approach where the body's own stem cells are used to build new blood vessels:

Adult stem cells are found throughout the body --- in the brain, bones, muscle, skin and blood --- which help heal the body after injury. But now, researchers are using high concentrations of these cells to actually build new arteries in adult patients.

"What we do is actually take them out and find the right amount of cells and specifically put them into targeted areas," said Dr. Amit Patel, director of the Cardiac Stem Cell Therapies at The McGowan Institute for Regenerative Medicine, University of Pittsburgh Medical Center.

Results in more than 100 patients show that, within just three months after the stem cell injections, patients see a significant improvement in blood flow to the heart. The heart muscle itself actually doubles its ability to squeeze or contract.
