Description:Magnified 1125X, this thin film photomicrograph of a blood smear, revealed the presence of a leukocyte (white blood cell, WBC) known as a monocyte.
Produced in the bone marrow, monocytes are a part of the immune system, able to differentiate into both macrophages, and what are known as “dendritic cells”, which process antigens, and presents them to other immune system cell types. Under normal circumstances, monocytes occupy approximately 3% - 8% of the white blood cell population.
