摘要: The maintenance of stemness normal stem cell is a complex process, where transcription factors like Oct-4, Bmi-1, and signaling pathways such as Wnt/β-catenin play important roles. This molecular set mechanisms not only expands the population (self-renewal) but also keeps cells in state “de-differentiation.” Thus, differentiation are mutually exclusive tightly regulated, idea variation over time has been incorporated. However, unlike stemness, tumor may be complexity microenvironment, especially hypoxic stress allow for stemness.
