Long-term expansion of human functional epidermal precursor cells: promotion of extensive amplification by low TGF-β1 concentrations
2 Sept 2003
Abstract excerpt
We have previously introduced the concept of high proliferative potential-quiescent (HPP-Q) cells to refer to primitive human hematopoietic progenitors, on which transforming growth factor-beta1 (TGF-beta1) exerts a pleiotropic effect. TGF-beta1 confers to these slow-dividing cells a mitogenic receptor(low) phenotype and maintains immature properties by preventing differentiation and apoptosis. However, the...
