[Alterations in concanavalin A binding during retinal development in Xenopus laevis].
Changes in concanavalin A binding were observed in the retina of Xenopus laevis throughout development. Prior to stage 37, the optic cup and nervous sysetm displayed a light, diffuse staining. Abruptly at stage 37, however, intense staining reaction occurred in the ganglionic fibers, both plexiform layers and photoreceptor inner segments, remaining thus throughout larval and adult life. Our results suggest that important structural modifications occur in retinal cells at the time of establishment of connections with the tectum, preceedings, and possibility related to, electrical functioning of the visual system.
