Тезаурус:

1. Following the pre-meiotic 5-phase interval, the cells proceed as spermatocytes through a long meiotic prophase and then through the two cell divisions leading to the production of haploid gametes.
2. The appearance of the pairing events in the SC reflect exactly the pairing behaviour of the meiotic chromosomes throughout prophase.
3. In addition, a new and powerful tool in the form of spreading for meiotic prophase analysis, has been introduced over recent years.
4. In Xenopus embryos, the intracellular level of calcium oscillates during the cell cycle, reaching a peak at mitosis, when it seems to be responsible for triggering nuclear envelope breakdown at prophase.
5. Meiotic prophase in the mouse commences on day 13 of gestation with maximum numbers of pachytenes being seen over days 16 - 18.
6. The first meiotic division in the female starts during embryogenesis and the prophase stages up to diplotene are found only in the fetal ovary.
7. In recent years, significant developments in the preparation of fetal oocytes in man and the mouse by microspreading, have taken place, and because of the superior quality of the preparations and the vast improvement in detail which can be discerned in such spreads, all discussion regarding chromosome preparation at meiotic prophase in oogenesis will be deferred until later (Section 4.3).
8. Application of the technique to mammalian spermatocytes, pioneered by Moses (37-;39), has demonstrated its potential for the analysis of the behaviour of chromosome abnormalities at meiotic prophase as well as the analysis of normal meiotic development.
9. The introduction of a simple and rapid surface microspreading technique for the visualization of the synaptonemal complex at meiotic prophase in insect spermatocytes (36) has revolutionized our understanding of the behaviour of chromosomes during this important stage of meiosis.
10. MICROSPREADING FOR PROPHASE ANALYSIS
11. In the human female, meiosis commences towards the end of the first trimester of fetal development and, with increasing gestational age, more and more cells enter the prophase stages of leptotene, zygotene and pachytene.
12. Early cytogenetic studies of meiotic prophase in females employing the use of air-drying techniques in the mouse, include those of Rohrborn and Hansmann (22), and in man, those of Luciani and Stahl (23) and Kurilo (24).
13. 3.1 Meiotic prophase
