用Nissl和Cox染色法观察48只生后不同发育阶段大鼠的小脑皮质。大鼠小脑皮质的外颗粒层生后继续增厚,于第7～10天达到高峰,以后急剧变薄,至第20天后完全消失。浦氏细胞是小脑皮质中分化较早的神经元,生后即可辨认。第13～16天的小脑皮质中出现数量较多的Bergmann胶质细胞,与颗粒细胞的迁移有关。蓝细胞与星状细胞均起源于外颗粒层,分化较迟。 The cerebellar cortex of 48 rats of different developmental stages after birth was observed by Nissl and Cox staining. The outer layer of rat cerebellar cortex continued to thicken after birth and reached its peak on the 7th to 10th days, then thinned sharply and completely disappeared after the 20th day. Puce cells are differentiated neurons in the cerebellar cortex, can be identified after birth. A large number of Bergmann glia appeared in the cerebellar cortex on the 13th to 16th day, which was related to the migration of granulosa cells. Blue cells and stellate cells originate from the outer granular layer, the late differentiation.
