It's usually assumed that stem cells differentiate via a set of "instructions" and prescribed pathways. However, new research shows that the decision is made collectively by an entire network of genes and proteins -- through a simple, elegant system that maintains cells in a stable state, yet...

Scientists Developing Transfusable Blood from Stem Cells

medgadget.com     May 23, 2008          

One day blood donation may become a thing of the past. Scientists at the RIKEN BioResource Center in Tsukuba, Japan are developing stem cell techniques that could lead to growing red blood cells in vitro, possibly making blood donation obsolete. The research team, led by Yukio Nakamura, initially...
