title: Loss of focal contacts accompanies the density dependent inhibition of cell growth.
abstract: The formation of focal contacts by fibroblast-like 3T3 and 9390 cells and endothelial XTH-2 cells was examined with the use of reflection interference contrast microscopy at different cell densities. It was found that cells density-inhibited in growth loose all focal contacts with the substratum. This observation explains the disappearance of stress fibers in density-inhibited cells, and also offers an explanation for the mechanism of density-dependent inhibition of proliferation of anchorage-dependent cells.
