Figure 5. Scanning electron micrograph of isolated microglia cells from brain tissue. (A) Microglia recovered from early embryonic developing brain show many of them retain spines bearing surfaces which radiate out of the cell body ; (B) a few cells remain amoeboid in shape with a ruffled surface membrane and short stubby projections in late embryo; (C) in neonates, the presence of both amoeboid cells with spines bearing surfaces and also extended structure of amoeboid microglia cell; (D) ramified or "resting" microglia isolated from adult brain with extended pseudopodia are seen
