Enhanced stem cells promote tissue regeneration

Published in Blood Weekly, October 22nd, 2009

MIT engineers have boosted stem cells' ability to regenerate vascular tissue (such as blood vessels) by equipping them with genes that produce extra growth factors (naturally occurring compounds that stimulate tissue growth). In a study in mice, the researchers found that the stem cells successfully generated blood vessels near the site of an injury, allowing damaged tissue to survive.

Why it matters: Stem cells hold great potential as a way to promote tissue regeneration. However, this approach has been limited because stem cells don't produce enough growth factors after transplantation. The researchers' new super-charged stem cells could be used to treat an infarction...
