Fixed retinae of chick embryos and chicks of the first week after hatching were fractured and examined with the scanning electron microscope. The matrix cells of the retina proliferate up to the beginning of the second week. The migrating cells are oriented in cell cords. This columnar organizaion prevails up to the development of the plexiform layers formed as a consequence of the outgrowth of the dendritic and axonal cell processes. Special attention was paid to the differentiation of the ganglion, bipolar and receptor cells, and the radial fibers (Müller cells). Two main morphological patterns are significant for the organization of the retina during neurogenesis: a)the cell to cell contacts of migrating cells and b)the spatial arrangement of Müller cells which could provide guidelines for migration of neuronal elements.
对孵化后第一周的鸡胚和雏鸡的固定视网膜进行断裂处理，并用扫描电子显微镜检查。视网膜的基质细胞增殖至第二周开始。迁移细胞排列成细胞索。这种柱状组织一直存在，直到由于树突状和轴突状细胞突起的生长而形成丛状层。特别关注了神经节细胞、双极细胞和感受器细胞以及放射状纤维（米勒细胞）的分化。在神经发生过程中，有两种主要的形态模式对视网膜的组织形成具有重要意义：a）迁移细胞之间的细胞间接触；b）米勒细胞的空间排列，这可为神经元成分的迁移提供指导。
