title: A set of early-born neurons is distinctly labeled by several defined antibodies in the adult rabbit retina.
abstract: Retinal ganglion cells, cone photoreceptor cells, and horizontal cells arise earlier in ontogenesis than the other retinal cell types. Although during the first postnatal week of life much cell proliferation occurs in the rabbit retina, 3H-thymidine labeling shows that these particular neurons are already postmitotic in neonatal animals. We show here that, in the adult retina, these early-born neurons express antigens as neuron-specific enolase, HNK-1 epitope of N-CAM, and PGP 9.5 antigen, which are not expressed by the neurons later born. It is concluded that the mammalian retina contains two genotypically different sets of neuronal cells which can be distinguished by immunocytochemistry.
