Human embryonic stem cells remain embryonic because of epigenetic factors

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 heart or other specialized tissue.
