Researchers have discovered an added layer of complexity in the network that determines human embryonic stem cell fate. A report publishing online April 30th in the journal Cell, a Cell Press publication, shows that a microRNA known as miR-145 lowers the activity of three key ingredients in the "recipe" for making embryonic stem cells. The discovery may have implications for improving the efficiency of methods designed to reprogram differentiated cells into embryonic stem cell-like cells and for the use of those transformed cells in replacing cells lost to disease or injury, the researchers said (see also Research).
"The heart of the matter is that before this ...
