The first clear description of monocyte subsets by flow cytometry dates back to the late 1980s, when a population of CD16-positive monocytes was described. [6] [7] Today, three types of monocytes are recognized in human blood: [8] The classical monocyte is characterized by high level expression of the CD14 cell surface receptor (CD14 ++ CD16 ...
The monoblast is the first stage of monocyte-macrophage maturation. The developmental stages of the monoblast are: CFU-GM (pluripotential hemopoietic stem cell or hemocytoblast) -> monoblast -> promonocyte-> monocyte-> macrophage/dendritic cell. During their development, monocytes are present in large packs in all of the lymph nodes in the body ...
Monocytes, the largest type of white blood cell, share the "vacuum cleaner" (phagocytosis) function of neutrophils, but are much longer lived as they have an extra role: they present pieces of pathogens to T cells so that the pathogens may be recognized again and killed. This causes an antibody response to be mounted.

In anatomy the term reticuloendothelial system (abbreviated RES), often associated nowadays with the mononuclear phagocyte system (MPS), was employed by the beginning of the 20th century to denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells) from the blood circulation.
Monocytes form two groups: a circulating group and a marginal group that remain in other tissues (approximately 70% are in the marginal group). Most monocytes leave the blood stream after 20–40 hours to travel to tissues and organs and in doing so transform into macrophages [ 70 ] or dendritic cells depending on the signals they receive. [ 71 ]
The image on the left shows a monocyte actively phagocytizing an antibody-sensitized red blood cell. The image on the right shows multiple RBC that have been phagocytized by a single monocyte. The monocyte monolayer assay (MMA) is used to determine the clinical significance of alloantibodies produced by blood transfusion recipients. [1]
The first stage of the myeloid lineage is a granulocyte - monocyte progenitor (GMP), still an oligopotent progenitor, which then develops into unipotent cells that will later on form a population of granulocytes, as well as a population of monocytes. The first unipotent cell in granulopoiesis is a myeloblast. [5]
