(Created page with "'''Staining''': May Grunwald-Giemsa '''Organ''': Blood smear '''Description''': There is a marked increase in the number of WBCs compared to normal. Not only mature cells are visible (neutrophils, basophils, eosinophils), but also immature cells.

CML involves an extreme proliferation of the myeloid cell line, which includes those cell lines that develop from myeloblasts into basophils, eosinophils and neutrophils (not monocytes). Because of this can we see many immature WBCs in the peripheral blood smear. These immature cells are large, have small cytoplasm and large nuclei. | CML involves an extreme proliferation of the myeloid cell line, which includes those cell lines that develop from myeloblasts into basophils, eosinophils and neutrophils (not monocytes).
