Confocal image of double-labeled rat hippocampal tissue showing microglial and perivascular cells in relation to brain microvessels.  Parenchymal microglia and microvessels were labeled with a fluorescently conjugated isolectin, FITC-IB4 (green).  Perivascular cells, which affiliate with arterioles and venules, were labeled with antibodies against the ED-2 antigen (red).  Perivascular parenchymal microglia (arrows) are ED-2 negative.
