摘要

The enormous potential of stem cells in human therapeutics heightens the relevance of studies addressing the cellular mechanisms, which control their proliferation and fate choice decisions. While embryonic stem cells retain the ability to differentiate into most if not all the cell types of the adult, somatic stem cells retain a restricted potential to differentiate into most or all the mature cell types of the tissue that they are derived from. In this report we review the literature and concepts related to cytoplasmic and nuclear regulatory mechanisms, which confer the properties of pluripotency or multipotency on stem cells. The recent flurry of activity related to the induction of pluripotency in fibroblasts and other relatively mature cells has given us pause in considering the actual nature of the two extremes of terminal differentiation and 'stemness', and the apparent reversibility of both phenomena. An analysis of the current literature on mechanisms of pluripotency and multipotency could lead to a better understanding of the possibilities by which a cell may be maintained in a preferred state of differentiation or de-differentiation at will.
