Nasal one-third sized fragments were created from fully differentiated larval Xenopus eyes (stage 47). At various times post-surgery, animals were injected with tritiated thymidine. All animals were fixed 1 day post-injection. Animals injected 1 day post-surgery showed limited healing and thymidine labeling in the retina. In animals injected 1 week(More)
We examined relationships between healing observed during embryonic Xenopus retinal and optic nerve regeneration and resultant visuotectal pattern formation. Dorsal (D) and nasoventral (NV) 1/3 sized eye fragments were surgically created in stage 32 Xenopus laevis embryos. Gross anatomical healing modes of these fragments were examined 2 days post-surgery(More)
We examined the relationship between early healing modes and extra cell division (via tritiated thymidine incorporation) during embryonic retinal regeneration. Nasal (N) and dorsal (D) one-third sized eye fragments were surgically created in stage 32 Xenopus laevis embryos. Embryos were injected with tritiated thymidine two days postsurgery (stage 43), and(More)
