Abstract: | Summary The present study deals with the localization and development of S-100 protein-like immunoreactivity in the retina, ciliary body and iris of human fetuses. In the retina, numerous astrocytes, densely distributed in the nerve-fiber layer and ganglion-cell layer, were stained strongly with the S-100 antiserum. The first immunoreactive astrocytes occurred at the posterior pole of the retina and spread gradually outward and toward the ora serrata with increasing age. Müller cells were not immunoreactive for S-100 during development, except in the retina of the latest fetus examined. S-100 immunoreactivity was also found in the nonpigmented ciliary epithelium and posterior epithelium of the iris, both of which are developed from the inner wall of the optic cup. On the other hand, the pigmented epithelium extending from retina to iris, derived from the outer layer of the optic cup, was free of S-100 immunoreactivity. |
