Since the genetic material is required in cell division, red blood cells are not capable of mitosis. Thus, the replenishment of red blood cells would be the function of stem cells which differentiate then specialize to be red blood cell progenitors. These progenitor cells will then mature to become red blood cells.Introduction. Healthy human adults produce about 200 billion red blood cells (RBCs) daily to replace those lost by senescence.
