[Interaction of epithelial cells with the edges of fluid and solid lipid films].
Capping of Concanavalin A (Con A) on the surface of epithelial cells near the cell-cell contacts has been compared with that in the regions of cell contacts with the edges of lipid films. If the lipids are in "fluid" state, Con A is capped likely as on the free edges of epithelial sheets, while contacts with the edge of solid lipid film inhibit capping of Con A as do cell-cell contacts. The same is true for capping of liposomes adsorbed on the surface of epithelial cells. We suppose that solid rather than fluid domains in plasma membranes may play a significant role in establishing cell-cell contacts.
