Fig. 2From: HIV-1 Penetrates Coronary Artery Endothelial Cells by TranscytosisTransmission electron microscopy of CAEC. A monolayer of CAEC displays tight junctions at each cell border contacting the adjacent cell. Note cell thinness and paucity of vacuoles. The monolayer was grown on a terepthalate membrane (3 micron pore size) in a cell culture insert (Falcon Plastics). (B) Tight junction between two CAEC.Back to article page
