Part Descriptions

LP14313-8   Monocytes
A monocyte is a mononuclear leukocyte, intimately involved in the initiaton of an immune response. It also protects against blood-borne pathogens and migrates quickly to sites of infection in the tissues. Monocytes are usually identified in stained smears by their large bilobed nucleus. They are produced by the bone marrow from hematopoietic stem cell precursors called monoblasts. The monoblast is the first stage of monocyte maturation. The developmental stages (4 subtypes) of the monocytes are: monoblast, promonocyte, immature monocyte, and mature monocyte.
