Human ESCs are typically derived from cleavage-stage embryos cultured to the blastocyst stage, followed by inner cell mass mechanoisolation, expansion in vitro, and clonal isolation/expansion of ESC lines. Conversely, iPSC derivation typically begins with the somatic cell of choice being transduced with a reprogramming cocktail to initiate reprogramming. Reprogrammed cells are then allowed to proliferate and expand, prior to clonal expansion and derivation of individual clonal lines. These images were created using BioRender.
