A heart cell nucleus contains skin cell genes, as well as the genes that instruct stomach cells how to absorb nutrients. This suggests that in order for cells to differentiate -- to become different from one another -- certain genes must somehow be activated, while others remain inactive.

Researchers at the University of Minnesota Stem Cell Institute (SCI) have found the first evidence that adult bone marrow-derived cells can differentiate in vitro and in vivo into cells of all three embryonic germ layers (endoderm, ectoderm and mesoderm) in similar manner as embryonic stem cells (ES cells). ... > read more...

Researchers at the University of Minnesota's Stem Cell Institute have described how an existing genetic tool can be used to study how human embryonic stem cells differentiate. The research appears ... As seen in work done with mouse cells by knockdown and other genetic means, they showed that reducing the amount of oct4 in...
