Developmental restriction of mobility of concanavalin A receptors.

Trypsinized cells from embryonic chick neural retina redistributed concanavalin A receptors to patches and caps. Between 12 and 16 days of development, the ability to redistribute concanavalin A receptors declined. This restriction in mobility of the receptors was accompanied by changes in susceptibility to the capping-inhibitory drugs colchicine and cytochalasin B.
