Erythropoietin (EPO), a cytokine, is a hormone produced by the kidneys that functions as a targeted ery-throid growth factor. This hormone has the ability to stimulate red cell production through a receptor on the pronormoblast, the youngest red cell precursor in the

Figure 2.3 Blood cell formation from stem cells to mature cells. Notice the differentiation and maturation path from stem cells, through the CFU-GEMM to the LSC, terminating in mature cells into the peripheral circulation. IL, interleukin; CFU, colony-forming unit, GEMM, granulocyte, erythrocyte, monocyte, macrophage; LSC, lymphoid stem cell.
