Abstract

The nucleoli of oogonia and oocytes of rat ovaries during fetal and neonatal life were studied by light and electron microscopy. An evolution from atypical to typical nucleoli was shown. Nucleoli undergo a gradual increase in size and change from dense fibrillar bodies to complete nucleoli with pars fibrosa, pars granulosa, pars amorpha, and associated chromatin.

摘要

通过光学显微镜和电子显微镜对大鼠胎儿期和新生儿期卵巢的卵原细胞和卵母细胞的核仁进行了研究。结果显示核仁从非典型向典型演变。核仁大小逐渐增加,从致密纤维小体转变为具有纤维成分、颗粒成分、无定形成分及相关染色质的完整核仁。
