Researchers characterize stem cell function
Thu, 11 Mar 2010 00:00:00 EST
Researchers are the first to fully characterize a special type of stem cell, endothelial progenitor cells (EPCs) that exist in circulating blood, to see if they can behave as endothelial cells in the body when cultured on a bioengineered surface.

Mathematical model may offer better understanding of embryonic development
Tue, 09 Mar 2010 23:00:00 EST
A mathematical model can predict complex signaling patterns that could help scientists determine how stem cells in an embryo later become specific tissues, knowledge that could be used to understand and treat developmental disorders and some diseases.
