NewsBlog: [Entry posted at 5th March 2008 04:22 PM GMT] Hematopoietic stem cells (HSCs) are generated in the placenta, before the circulatory system is fully operational, researchers report is this week's issue of Cell Stem Cell. The finding offers researchers a better shot at defining the microenvironment required to grow HSCs in vitro.
Researchers have known that the placenta holds a reserve of HSCs, and had observed that when placental HSCs decline in number, the liver's reserve expands. Here, Katrin Rhodes... Click to continue
