[Female germ cell development during the meiotic prophase in the rat: criteria for cytoplasmic and nuclear identification of the different stages on thin histological slides]

Abstract

The different stages of meiotic prophase in germ cells of the rat ovary were studied cytologically at definite times when there was a dominant nuclear stage. Each stage was identified in 1 mu sections. The usual references for the definition of meiotic nuclear stages according to chromosomal structures wee used and have been described in more detail. It has also been shown that cytological observations such as the organization and distribution of cytoplasmic organelles (mitochondria, Golgi apparatus) equally contributes to the identification of the stages of meiotic prophase.
