Cellular plasticity. Phenotypic plasticity can enable stem cells and non-stem cells to shift among one another via different programs, depending on intrinsic (epigenetic) and extrinsic (tumor microenvironment) factors. VSC: vascular stem/progenitor cells; EC: endothelial cells; MSC: mesenchymal stem cells; TAM: tumor-associated macrophages; CAF: cancer-associated fibroblast; EMT: epithelial-mesenchymal transition; MET: mesenchymal-epithelial transition; EndMT: endothelial-mesenchymal transition.
