ErythrocyteDifferentiationPathway
Stem cells in the bone marrow produce a variety of hematopoietic cell types from common progenitor cells under the influence of cytokines and growth factors. CFU-GEMM cells are a key intermediate in the differentiation of granulocytes, erythrocytes, monocytes and megakaryocytes. Erythropoietin (EPO) is a cytokine produced in the kidneys that, along with other cytokines, induces red blood cell (erythrocyte) differenti......阅读全文
