They represent ~12% of the cells in the CNS, but they are not uniformly distributed within the CNS. A normal adult mouse brain has approximately 3.5x10e6 microglia. Microglia are also reportedly CD3-negative, CD4-positive, CD8-negative, CD11b-positive, CD11c-high, CD14-negative, CD19-negative, CD45-low, CD56-negative, CD163-negative, CD200R-positive, CD281-positive, CD282-positive, CD283-positive, CD284-positive, CD285-positive, CD286-positive, CD287-positive, CD288-positive, CD289-positive, Gr1-negative, nestin-positive, and PU.1-positive. microgliocyte FMA:54540 central nervous system macrophage oligodendrocyte precursor cell innate immune response integrin alpha-M adhesion G protein-coupled receptor E1 macrosialin central nervous system
