An important subject in stem cells research: the regulatory of retinoblastoma pathway for stem cells / 中华眼底病杂志

Stem cells are crucial for embryonic development and in the maintenance of adult cellular homeostasis.Understanding the regulatory network of stem cells,including embryonic and adult stem cells,will allow us to learn the pathogenesis and possibly design novel approaches to treat many diseases (such as cancer and degeneration).The retinoblastoma (Rb) pathway controls cellular proliferation,differentiation and death.More and more evidences support an important role of Rb activity in the biology of stem and progenitor cells.Transiently inactivating Rb pathway might favor the expanding of functional stem cell populations,thus have values in the future stem cell applications.
