目的:观察正常大鼠M-ller细胞在视网膜不同层面的形态分布特征。方法:应用光镜和透射电镜观察正常大鼠视网膜M-ller细胞的形态结构分布特征。结果:M-ller细胞不均匀分布于视网膜的各个层面,在内网状层、神经节细胞层和神经纤维层分布最多。结论:M-ller细胞不仅是视网膜的支架,而且在视网膜神经节细胞层与神经纤维层代谢活跃,是重要的神经胶质细胞。

AIM:To observe the distribution characteristics of M-ller cells of the normal rat retina in different levels.·METHODS:The morphological characteristics of the M-ller cells of the normal retina was studied by light microscopy and transmission electron microscope(TEM).·RESULTS:M-ller cells were not the relatively homogeneous distribution in every layer of the rat retina,which had the widest distribution in the inner plexiform layer,the ganglion cell layer and nerve fiber layer.·CONCLUSION:M-ller cells not only take part in composition of the stent of the rat retina,but also have the most active metabolism in the ganglion cell layer and nerve fiber layer.They are the important neuroglial cells.
