The possibility of transformation of the corneal anterior epithelium in the lens following its separation from the stroma was studied. The corneal epithelium was implanted into: a) empty eye orbit and b) cavity of lensless eye of the Rana temporaria tadpoles. In the eye orbit it continued, as in the normal development, to form the basal membrane. Although in the eye cavity the structures similar to lentoids arose but the specific lens proteins were shown to be asbent from them using immunofluorescence. In both the cases, thus, no transformation of the corneal epithelium in the lens was observed. The role of stroma in the stabilization of differentiation of the corneal anterior epithelium is discussed. It is suggested that the absence of increase in the mitotic activity is one of the causes of failure of the corneal epithelium transformation in the lens.
研究了角膜前上皮与基质分离后在晶状体中发生转化的可能性。将角膜上皮植入:a)空眼眶和b)泽蛙蝌蚪无晶状体眼的眼腔内。在眼眶中,它如同在正常发育过程中一样,继续形成基底膜。尽管在眼腔内出现了类似于晶状体样的结构,但利用免疫荧光显示其中不存在特定的晶状体蛋白。因此,在这两种情况下,均未观察到角膜上皮在晶状体中的转化。讨论了基质在角膜前上皮分化稳定中的作用。有人提出有丝分裂活性未增加是角膜上皮在晶状体中转化失败的原因之一。
