NORMAL DEVELOPMENT
Monocytopoietic cells originate in the bone marrow through the following developmental forms:
The maturation process and division in the bone marrow last 16 to 26 hours. After leaving the bone marrow, monocytes remain in the bloodstream about 7 days, then move into tissues, where they become macrophages. They can proliferate to a small extent, especially in the place of inflammatory reaction. Today it is indisputably clear that the monocytes in the blood and macrophages in the tissues are the same cell species. They are classified as mononuclear phagocytes.
