Megakaryoblast
Encyclopedia
A megakaryoblast is a precursor cell to a promegakaryocyte
, which in turn becomes a megakaryocyte
during haematopoiesis
. It is the beginning of the thrombocytic series.
It derives from a CFU-Me colony unit of pluripotential hemopoietic stem cell
s. (Some sources use the term "CFU-Meg" to identify the CFU.)
Promegakaryocyte
A promegakaryocyte is a precursor cell for a megakaryocyte, arising from a megakaryoblast.The developmental stages of the megakaryocyte are:CFU-Me → megakaryoblast → promegakaryocyte → megakaryocyte.-External links:* *...
