The neural marker neuron-specific enolase in the development of embryo chicken retina: a morphological description.

The localisation and distribution of Neuron-specific enolase is reported in the avian Gallus domesticus retinal development by using immunocytochemistry. Neuron specific enolase was found to be present from the early days of incubation to the post-hatch period. The results obtained using this neural marker showed the development pattern of the distribution and the sequence of differentiation of the retinal neural structures. Like the finding of the members of the phylogenetic scale, this enzyme should prove to be a useful tool in the neural development of the chicken retina.
