Future of Engineering

For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients' heads, according to new research published earlier this month by University at Buffalo engineers.

"Engineering blood vessels for bypass surgery, promoting the formation of new blood vessels or regenerating new skin tissue using stem cells obtained from the most accessible source -- hair follicles -- is a real possibility," said Stelios T. Andreadis, Ph.D., co-author of the paper in Cardiovascular Research and associate professor in the Department of Chemical and Biological Engineering in the UB School of Engineering and Applied Sciences.

Researchers from other institutions previously had shown that hair follicles contain stem cells.
In the current paper, the UB researchers demonstrate that stem cells isolated from sheep hair follicles contain the smooth muscle cells that grow new vasculature. The group recently produced data showing that stem cells from human hair follicles also differentiate into contractile smooth muscle cells
