Vitronectin blocks fusion of epithelial cells but not of B cells. Vitronectin was added immediately after transfection of AGS cells with gB and gHgL (AGS:AGS), after transfection of CHO-K1 cells with gB, gHgL, and a luciferase construct and subsequently overlaid with 293T14 cells (CHO:293T14), or after transfection of CHO-K1 cells with gB, gHgL, gp42, and a luciferase construct, subsequently overlaid with Daudi29 cells (CHO:Daudi29) (black bars). Fusion is expressed as a percentage of that occurring in the absence of vitronectin (white bars). Error bars indicate SD of 3 experiments; the SD of AGS :AGS fusion in the presence of vitronectin is too small to visualize.
