to determine whether cytoskeletal proteins restrict the mobility of lh-receptor complexes occupied by hcg , we measured the rate of lateral diffusion and the fraction of mobile receptor-hormone complexes by fluorescence photobleaching recovery on luteal cells treated with microtubule and microfilament disruptors and on portions of the plasma membrane separated from the underlying cytoskeleton ( blebs ) .
