(A) Schematic figure showing major developmental transitions at which PRC2 functions, including (I) multipotent cell identity, (II) lineage commitment, (III) progenitor expansion, (IV) differentiation/cell fate choice.
(B) Reported tissues that are under regulation by PRC2 during development. Roman numbers represent steps from panel A that have been shown to be regulated by PRC2 while numbers refer to related citations on the reference list to the right. See text for details.
