Enhancement of differentiation of lens and pigment cells by ascorbic acid in cultures of neural retinal cells of chick embryos

Abstract

When dissociated cells of neural retinae of 9-day-old chick embryos were cultured in Eagle's minimum essential medium supplemented with dialyzed fetal calf serum, both the proliferation and differentiation of the neural retinal cells were inhibited. These cells remained quiescent and flattened. When ascorbic acid was added to such a medium, the cells started to grow and differentiated into lentoid bodies and pigmented cells after about 10 days.
