In addition, some cells in the ependymal layer, oligodendrocyte like cells and the network made from different cellular extensions or processes were located closely around the neuroblast like cells in the same area. 另外发现,室管膜(EL)细胞、EL深部细胞、少突胶质样细胞以及不同细胞突起所组成的网络样结构与上述SVZ成神经样细胞紧密相邻。
Two different kinds of glutamate positive structures were observed in the ependymal layer of the third ventricle for the first time: ( 1) glutamate positive ependymal cells with oval bidies always gathered into groups; 首次在大鼠下丘脑第三脑室室管膜内观察到两种不同类型的Glu免疫反应结构:(1)Glu免疫反应性室管膜细胞,胞体呈椭圆形,常聚集成群;
E21  ̄ 30d, the neural tube differentiates the ependymal, the mantle and the marginal layer, the spinal and the sympathetic ganglion. E21~31d,神经管已分化出室管膜层、外套层、边缘层、脊神经节、脊神经及交感神经链。
They were located in the ependymal layer, sub ependymal layer or region with some distance to the ependyma, sending processes into the third ventricle. 它们位于脑室管膜内、室管膜下,或距室管膜有一定距离处,但有突起伸至第三脑室。
Widespread labelled efferent fibres with numerous varicosities were found in or beneath the ependymal layer in certain locations of ventricular system. 在脑室系统某些部位的室管膜层或其下方见有丰富的标记纤维并见许多膨结和终末膨突。
When the cells of ependymal layer stopped to migrate, the ependymal layer began to transform into pseudostratified columnar and simple columnar epithelium. 当室管膜层细胞停止迁徙时,室管膜开始向假复层柱状及单层柱状上皮转变。电镜观察,胚胎早期神经上皮细胞由未分化细胞构成;
Results showed that hypothyroidism could reduce proliferation cells, prolong proliferating time in the developing brain; retard the cell migration from ependymal and subependymal layers to internal granule layer in olfactory bulb; 结果表明:甲低时,①嗅球嗅室壁室管膜及其下层细胞增殖延迟,细胞向内颗粒层迁移的速度减慢;
