Promegakaryocyte

A promegakaryocyte is a precursor cell for a megakaryocyte, arising from a megakaryoblast. A promegakaryocyte is a precursor cell for a megakaryocyte, arising from a megakaryoblast. The developmental stages of the megakaryocyte are:CFU-Me (pluripotential hemopoietic stem cell or hemocytoblast) → megakaryoblast → promegakaryocyte → megakaryocyte. When the megakaryoblast matures into the promegakaryocyte, it undergoes endoreduplication and forms a promegakaryocyte which has multiple nuclei, azurophilic granules, and a basophilic cytoplasm. The promegakaryocyte has rotary motion, but no forward migration.
