Sertoli-Sertoli-germ cell tight and adherent junctions may play an essential role in spermatogonial stem cells (SSCs) to differentiate spermatocytes and functional haploid spermatozoa.In this study, we have developed a new SSC culture system with Sertoli cells that could derive spermatocytes and haploid cells from SSCs.We observed that the in vitro derived spermatocytes could regulate the relevant tight and adherent junctions;We have provided sufficient evidence to show that the Sertoli cells play a significant role in contributing to the mature haploid cells derived from the cultured SSCs.These results suggest that in vitro induced haploid cells from SSCs structurally and nutritionally rely on the Sertoli cell supports for their development and differentiation through theft cell junctions.This in vitro system could not only facilitate the exploration of genes involved in SSCs differentiation and may also discover potential targets used to perturb spermatogenesis for developing a novel male contraceptive.

溶血磷脂酸(Lysophosphatidic acid,LPA)和磷脂酸(phosphatidic acid,PA)是参与细胞内信号转导以及脂质体合成的两种主要磷脂.LPA转化成PA的反应时磷脂合成的第二步反应,这步反应由溶血磷脂酸酰基转移酶(Lysophosphatidic acid acyltransferase,LPAAT)所催化.LPAAT也叫做1-酰基甘油-3-磷酸-酰基转移酶(1-ac
在胚胎着床的子宫内膜容受性形成及蜕膜化过程中,胚胎滋养层细胞对子宫内膜的有控性侵袭是胎儿正常发育的基础。虽然目前对miRNA与子宫内膜容受性的关系仍不十分清楚,但是已有一些研究表明,在正常妊娠胎盘、绒毛和正常子宫内膜中,一些miRNA与靶基因存在一定的的互作关系。我们通过小RNA测序分析在早孕和流产蜕膜中的差异microRNA表达,发现在已知的1921条miRNA中有37个差异表达,并对表达量前1

本研究使用不同浓度TSA处理牛胎儿成纤维细胞，观察对细胞生长状态、组蛋白乙酰化水平的影响，检测表观修饰相关基因和多能基因表达及多能基因启动子区DNA甲基化的变化。研究表明：TSA处理能够提高牛胎儿成纤维细胞整体组蛋白H3K9, H3K14乙酞化和H3K9三甲基化水平，上调多能基因OCT4和NANOG的表达，这些变化可能有利于使成纤维细胞处于更适合的核移植供体状态。
