Regulation of maturation in meiotically competent mammalian oocytes is a complex process involving the carefully coordinated exchange of signals between the somatic and germ cell compartments of the ovarian follicle via paracrine and cell-cell coupling pathways. This review highlights recent advances in our understanding of how such signaling controls both meiotic arrest and gonadotropin-triggered meiotic resumption in competent oocytes and relates them to the historical context. Emphasis will be on rodent systems, where many of these new findings have taken place. A regulatory scheme is then proposed that integrates this information into an overall framework for meiotic regulation that demonstrates the complex interplay between different follicular compartments.
在具有有丝分裂能力的哺乳动物卵母细胞中,成熟的调控是一个复杂的过程,涉及到通过旁分泌和细胞间连接途径,在卵巢滤泡的体细胞和生殖细胞区室之间进行信号的精心协调交换。这篇综述强调了我们对这些信号如何控制有丝分裂阻滞和促性腺激素触发的有丝分裂恢复的理解的最新进展,并将其与历史背景联系起来。重点将放在发生这些新发现的啮齿动物系统上。然后提出了一个调节方案,将这些信息整合到一个有丝分裂调节的整体框架中,展示了不同滤泡区室之间的复杂相互作用。
