title: [Effect of agents disrupting microtubules on the distribution of receptors on the surface of cultured cells].
abstract: Substrate-attached normal mouse fibroblasts, transformed mouse fibroblasts (L-strain) and epithelial cells (MPTR strain) were incubated with two ligands that are cross-linking different group of the surface receptors: concanavalin A and cationic ferritin. Surface-attached ligands were revealed by the indirect immunofluorescent methods. The incubation of control cells with these ligands induced a patching of corresponding surface receptors, and a clearing of these receptors from the surface zones located on the lamellar cytoplasm near the cell edges actively protruding pseudopodia. Effects of three antitubulins (colcemid, colchicine and vinblastin) on the ligand-induced redistribution of receptors were examined and compared with the previously described effects of these drugs on the distribution of active cell edges.
