IntroductionThe Nobel Prize—It is not just an award. Differentiated cells can be reprogrammed to an embryonic-like state by transfer of nuclear contents into oocytes or by fusion with embryonic stem (ES) cells. 0000116322 00000 n 0000006446 00000 n 0000021227 00000 n 0000039409 00000 n 0000009155 00000 n
