Article: Oocytes from pachytene to dictyotene can easily be analysed in neonatal rodents

We have investigated the dynamics of meiotic prophase I in neonatal ovaries from different wild rodent species, from a laboratory strain of Mus musculus and from Mus musculus x Mus spretus F1 hybrids. We found that almost all stages of prophase I were regularly present in neonatal ovaries from these species and that their transcriptional activity can be assessed by [3H]-uridine incorporation, indicating that postnatal analysis of meiotic chromosomes and synapsis may be conducted as an alternative to the investigation of foetal ovaries.
