- ‘What he showed next were a series of experiments in which they pushed cultured, totipotent mouse embryonic stem cells to desired neural fates using the various factors he had identified as significant in vivo.’
- ‘Thus, unlike totipotent single-cell embryos, pluripotent embryonic stem cells are specialized cells that have limited developmental capabilities.’
