a Integration of a clonal evolution and cancer stem cell model for gliomagenesis. This model assumes that sequential mutations and selection pressure drive the evolution of cancer stem-like cells. At the same time, these stem-like cells may give rise to more differentiated (i.e., phase IV) offspring that may divide further but rapidly become growth arrested. b According to this model these cells may be senescent and contribute to the cancer phenotype by eliciting a microenvironment response via SASP. SASP senescence-associated secretory phenotype; ILs interleukins; CXCLs chemokines (C–X–C motif); CCLs chemokines (C–C motif)
