Question

Quizplus · Accepted Answer

The myeloblast is the earliest morphologically identifiable cell in the granulocyte maturation sequence, which gives rise to the Promyelocyte, Myelocyte, Metamyelocyte, and finally the mature Granulocyte. A) Pluripotent stem cell is the precursor to all blood cells, but not a recognizable cell in the granulocyte maturation sequence. B) CFU-GEMM is the precursor to multiple blood cell lineages, not just granulocytes. D) Myelocyte is a later stage in the granulocyte maturation sequence, after the myeloblast, promyelocyte, and myelocyte.
