Fig. 1. Distribution of cytoskeletal proteins in low-density and high-density cells. X-Z Optical sections of the intercalated cell line cultured at low density, high density and at low density but on the extracellular matrix of high-density cells. The cells were stained by phalloidin and with antibodies to villin and cytokeratin 19. Note the cell height in high-density cells and in cells seeded on high-density matrix.
