Pigment cell development in rhesus monkey eyes: an electron microscopic and histochemical study

, : Pigment cell development in rhesus monkey eyes: an electron microscopic and histochemical study. Developmental Biology 32(1): 69-81

The ontogeny of pigment cells in the eyes of rhesus monkeys was studied by electron microscopy and histochemistry.In 60- to 80-day-old fetuses, the pigment epithelium of the iris and retina has already differentiated whereas stromal melanocytes of the uveal tract differentiate much later. The morphological and histochemical difference between melanocytes of the iris stroma and the choroid suggests that during embryonic development melanocytes migrate from the iris toward the ciliary body and choroid.Similarly, melanosomes of pigmented epithelial cells may have their origin in the epithelium of the anterior layer of the iris, which is metabolically more active than both the posterior layer and the pigment epithelium of the ciliary body and retina.
