Stem Cells Hold Keys to Body’s Plan

Case Western Reserve researchers have discovered landmarks within pluripotent stem cells that guide how they develop to serve different purposes within the body. This breakthrough offers promise that scientists eventually will be able to direct stem cells in ways that prevent disease or repair damage from injury or illness.

New study shows reprogrammed amniotic fluid cells could treat vascular diseases

Their study paints a picture of a future therapy where amniotic fluid collected from thousands of amniocentesis procedures yearly, during mid-pregnancy to examine fetal chromosomes, would be collected with the permission of women undergoing the test. These cells, which are not embryonic, would then be treated with a trio of genes that reprogram them quickly into billions of endothelial cells -- the cells that line the entire circulatory system. The new endothelial cells could be frozen and banked the same way blood is, and patients in need of blood vessel repair would be able to receive the cells through a simple injection.
