Hematopoiesis: MEP differentiates into megakaryocytes and erythrocytes.

Megakaryocyte–erythroid progenitor cells (MEPs), among other blood cells, are generated as a result of hematopoiesis, which occurs in the bone marrow. Hematopoietic stem cells (HSC) 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–erythroid 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–erythroid progenitor progenitor cells. [4]

Megakaryopoiesis: Megakaryocyte actively forming platelets.
