After nerve injury, the increased production of Epo may induce activation of certain cellular pathways, while the concentration of EpoR doesn’t change. In Schwann cells, increased erythropoietin levels may stimulate Schwann cell proliferation via JAK2 and ERK/MAP kinase activation to be explained later. Similar to stimulation of red blood cell precursor cells (erythrogenesis), erythropoietin stimulates non-differentiated Schwann cells to proliferate.
