Abstract:The age-dependent microscopic structure of the retina was observed under light microscope, and the immunohistochemical localization and expression intensity of glial fibrillary acidic protein (GFAP) were statistically analyzed. The results showed that the retina of the S.tsinlingensis was divided into 10 layers from the inside to the outside, which was consistent with the retina structural characteristics of lizards. The total retinal thickness of sub-adult and adult retina increased significantly compared with larvae, but there was no significant difference in the thickness of ganglion cells layer, outer limiting membrane, and layer of rods and cones. There was no difference in the number of retinal nucleus layers in different age groups, which were composed of 1-2 layers in the outer nuclear layer, 3-4 layers in the ganglion cells layer and 6-8 layers in the inner nuclear layer. The immunoreactivity of GFAP in the retina was mainly located in the inner limiting membrane and the nerve filament layer, and the nerve fiber layer was the most positive. The positive expression of GFAP in the retina showed age-related changes, i.e. the adult groups > the larvae groups > sub-adult groups. The expression of GFAP positive in the retina of the S.tsinlingensis is related to age, which may be involved in the regulation of physiological functions during the development of retina.
