Comparison of monoblast, promonocyte and monocyte. A typical monoblast is about 12 to 20 μm in diameter, has a nuclear to cytoplasm ratio of 4:1 to 3:1, and, like most myeloid blasts, has a round to oval nucleus with fine chromatin structure. Compared to other myeloid blasts, monoblasts have more cytoplasm. [5]

Monocyte count >1x10 9 /L; 0–19% blasts in bone marrow <5% blasts in peripheral blood; The FAB also arbitrarily categorises CMML into myelodysplastic-like and myeloproliferative-like groups. A white blood count of 13x10 9 is used as a cut-off to differentiate the two. [12]
A comprehensive diagram of human hematopoiesis. Granulopoiesis consists of 5 stages, in which the myeloblast is the first recognizable cell. Next in the differentiation sequence is the monoblast and the promyelocyte, which can develop into one of three different precursor cells: the neutrophilic, basophilic or eosinophilic myelocyte.
Said et al. showed that activated monocytes express high levels of PD-1 which might explain the higher expression of PD-1 in CD14 + CD16 ++ monocytes as compared to CD14 ++ CD16 − monocytes. Triggering monocytes-expressed PD-1 by its ligand PD-L1 induces IL-10 production, which activates CD4 Th2 cells and inhibits CD4 Th1 cell function. [ 23 ]
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
Acute monocytic leukemia (AMoL, or AML-M5) [2] is a type of acute myeloid leukemia.In AML-M5 >80% of the leukemic cells are of monocytic lineage. [3] This cancer is characterized by a dominance of monocytes in the bone marrow.
Testing available to diagnosis AML includes a complete blood count which is characterized by blood that is taken from the vein in the arm to test for leukemia, a peripheral blood smear and a bone marrow test. During a peripheral blood smear, a sample of blood is checked for blast cells, white blood cell count and changes in shape of blood cells ...
