Phagocytosis of fluorescent beads and E. coli particles. a Fluorescence microscopic image of an astrocyte marked with anti-GFAP antibody (red) after incubation with fluorescent beads (green). b Fluorescence microscopic image of a cell of microglia marked with anti-Iba1 antibody (red) after incubation with fluorescent beads (green). c Confocal projection image of an astrocyte after E. coli (green) phagocytosis. d Z-stack image of the same astrocyte. The dotted line delineates the limits of the cell cytosol. Cell nuclei were stained with DAPI. Scale bar 25 μm
