摘要
Epithelial-mesenchymal transition(EMT),mesenchymal-epithelial transition(MET),and even the sequential EMT-MET can be observed during multiple cell fate conversions including cancer progression and embryonic development.In the current review,we first focused on the existence and beneficial roles of the sequential EMT-MET during three typical cell fate conversions,differentiation from pluripotent stem cells(PSCs)to neurons,de-differentiation from mouse embryonic fibroblasts(MEFs)to PSCs,and trans-differentiation from MEFs to neurons.We tried to provide some preliminary hypotheses to connect EMT-MET and cell fate conversions,like the possible contributions of the intermediate mesenchymal state to iPSCs generation and neurontrans-differentiation.The intermediate mesenchymal state during sequential EMT-MET was further discussed by exploring the conserved signatures on gene expression during a variety of EMT.Discussion on the interaction among vitamin C,DNA methylation,and EMT/MET was also provided.
