Megakaryocyte–erythroid progenitor cell

Megakaryocyte–erythroid progenitor cells, among other blood cells, are generated as a result of hematopoiesis, which occurs in the bone marrow. Hematopoietic stem cells can differentiate into one of two progenitor cells: the common lymphoid progenitor and the common myeloid progenitor. MEPs derive from the common myeloid progenitor lineage.[1] Megakaryocyte/erythrocyte progenitor cells must commit to becoming either platelet-producing megakaryocytes via megakaryopoiesis or erythrocyte-producing erythroblasts via erythropoiesis.[2][3] Most of the blood cells produced in the bone marrow during hematopoiesis come from megakaryocyte/erythrocyte progenitor cells.[4]

Megakaryopoiesis: Megakaryocyte actively forming platelets.
Hematopoiesis: MEP differentiates into megakaryocytes and erythrocytes.
