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 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)
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)
