膜内颗粒的矩阵排列(OAP)是星形胶质细胞终足膜的特征,亦见于视网膜Muller细胞的终足膜中。但尚末弄清Muller细胞终足膜中OAP的生后发育。本文用冷冻断裂技术研究了生后早期和成年家兔的视网膜,试图了解OAP在终足膜中的分布和密度。在成年动物,观察到中 The matrix arrangement of intraparticles (OAP) is a characteristic of the astrocyte terminal podocyte and is also found in the terminal podocyte of the retinal Muller cells. However, we did not understand the postnatal development of OAP in Muller cells. In this paper, the retina of early postnatal and adult rabbits was studied by cryogenic fracture technique in an attempt to understand the distribution and density of OAP in the terminal parenchyma. In adult animals, observed
