- H3K4me3 And H3K27me3 Keep Embryonic Stem Cells Embryonic
A human embryonic stem cell is reined in – prevented from giving up its unique characteristics of self-renewal and pluripotency – by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into hear ...
