Background:Germ cell mitotic arrest is conserved in many vertebrates,including birds,although the time of entry or exit into quiescence phase *** arrest is essential for the normal differentiation of male germ cells into spermatogonia and accompanies epigenetic reprogramming and meiosis inhibition from embryonic development to ***,mitotic arrest was not well studied in chickens because of the difficulty in obtaining pure germ cells from relevant developmental ***:We performed single-cell RNA sequencing to investigate transcriptional dynamics of male germ cells during mitotic arrest in dazl::gfp *** differentially expressed gene analysis and K-means clustering to analyze cells at different developmental stages(E12,E16,and hatch),we found that metabolic and signaling pathways were regulated,and that the epigenome was reprogrammed during mitotic *** particular,we found that histone H3K9 and H3K14 acetylation(by HDAC2)and DNA demethylation(by DNMT3B and HELLS)led to a transcriptionally permissive chromatin ***,we found that global DNA demethylation occurred gradually after the onset of mitotic arrest,indicating that the epigenetic-reprogramming schedule of the chicken genome differs from that of the mammalian *** hypomethylation persisted after hatching,and methylation was slowly re-established 3 weeks ***:We found a unique epigenetic-reprogramming schedule of mitotic-arrested chicken prospermatogonia and prolonged hypomethylation after *** will provide a foundation for understanding the process of germ-cell epigenetic regulation in several species for which this process is not clearly *** findings on the biological processes related to sex-specific differentiation of prospermatogonia could help studying germline development in vitro more elaborately.
