Deficiency of microRNA miR-34a expands cell fate potential in pluripotent stem cells.

A summary is presented of the article "Deficiency of microRNA miR-34a expands cell fate potential in pluripotent stem cells," published in the online version of the journal. Topics discussed include the generation of embryonic and extraembryonic lineages in teratomas and the role of protein-coding genes, noncoding RNAs, and endogenous retroviruses in stem cell development.
