In vitro production of viable eggs from isolated mouse primary follicles by successive culture
The Journal of Reproduction and Development, 2021 To produce viable eggs from single primary follicles in vitro, primary follicles containing oocytes (average 39.0 ± 0.2 µm in diameter) were isolated from the ovaries of 1-week-old mice, and cultured in combination with culture membranes for the first 8 ...

Rat PRDM9 shapes recombination landscapes, duration of meiosis, gametogenesis, and age of fertility
BMC Biology, 2021 Background Vertebrate meiotic recombination events are concentrated in regions (hotspots) that display open chromatin marks, such as trimethylation of lysines 4 and 36 of histone 3 (H3K4me3 and H3K36me3).
