Self-renewal

Self-renewal is the process of giving rise to indefinitely more cells of the same cell type. All stem cells have the capacity to self-renew by dividing.

    Haematopoietic stem cells (HSCs) are maintained in vivo by intrinsic programs and extrinsic niche signals. Ex vivo expansion of HSCs is limited, owing to reduced stem cell maintenance factors. A study now shows that rejuvenated niche cells can be obtained by transcriptional rewiring of specific genes that maintain and expand HSCs ex vivo.

    The cancer-suppressive mechanisms underlying a tissue’s response to spontaneous oncogenic mutations during homeostasis are largely unknown. A study now explores how clonal expansion of epidermal stem cells with specific oncogenic mutations might be restricted by their elimination through enforced differentiation.

    The dogma that self-renewal is a defining characteristic of stem cells, which stemmed from studies of the hematopoietic hierarchy and quickly spread by analogy to all tissues, has been shattered by scientists pointing a microscope at the hematopoietic system itself. A microglial cell is clearly fully differentiated, and yet it self-renews.
