without embryonic stem cells the process for making these induced pluripotency cells would never have been discovered.
The genes required for such reprogramming are intimately involved in the mechanisms that embryonic stem cells use to maintain their phenotype. Indeed without the extensive studies that have gone on in both human and mouse ES cells we would be completely ignorant about the roles of these genes.
A little research will make you sound a whole less ignorant.
