角膜是视觉器官的一个重要组成部分,角膜内皮细胞层在解剖形态和生理功能上的完整性是保持角膜透明性的关键。近年来国内外许多学者致力于角膜内皮的研究,在其胚胎发育、形态结构、生理功能、生化特性及病理改变诸方面均取得了一些进展。现将有关资料综述如下: 一、角膜内皮细胞层的胚胎发育——神经嵴细胞分化学说的产生传统的看法认为角膜内皮来源于中胚层,1861年Kolliker确立了这一学说,他认为逐
The cornea is an important part of the visual organ. The anatomical and physiological integrity of the corneal endothelial cell layer is the key to maintaining the transparency of the cornea. In recent years, many scholars at home and abroad devoted themselves to the study of corneal endothelium, and made some progresses in aspects of embryonic development, morphological structure, physiological function, biochemical characteristics and pathological changes. Now the relevant information is summarized as follows: First, the embryonic corneal endothelial cell layer development - neural crest cell differentiation theory that the traditional view that the corneal endothelium derived from the mesoderm, Kolliker in 1861 established this theory, he believes that by
