Etymology: Gk, myelos + blastos, germ
one of the earliest precursors of the granulocytic leukocytes. The cytoplasm appears light blue, scanty, and nongranular when seen in a stained blood smear through a microscope. The nucleus contains distinct chromatin material in strands, together with several nucleoli. In certain leukemias a marked increase in myeloblasts is observed in the marrow and in the peripheral blood. Compare megaloblast, myelocyte, normoblast. See also myelocytic leukemia. myeloblastic, adj.
