Bidirectional communication between oocytes and follicle cells: ensuring oocyte developmental competence

Abstract: Female fertility is determined to a large extent by the quality (developmental competence) of the oocyte as reflected in its ability to undergo meiosis, be fertilized, and give rise to a healthy embryo. Growth of the mammalian oocyte is coordinated with that of the follicle that encloses it by the actions of signals that pass in both directions between the germline and somatic components. This review summarizes what is known about the roles played by two different modes of intrafollicular signalling in oogenes… Show more

“…Bidirectional communication between the oocyte and surrounding cumulus cells (CCs) is essential for the acquisition of oocyte competence [21]. It has been previously reported that because of their close connection with the oocyte, CCs may retain a footprint of the follicular conditions experienced by the oocyte [22].…”

“…These COC-like structures are capable of producing estradiol, which indicates the presence of both granulosa and theca cells [11]. However, whether they incorporate the proper architecture for cumulus-oocyte communication, including the gap junctions that normally couple oocytes and their surrounding somatic cells into a functional syncytium [12], remained unclear.…”

“…Следовательно, некомпе-тентность фолликуло-и оогенеза может быть уста-новлена на завершающих этапах фолликулярного роста. По данным литературы [9,19], ВМР15 и Cx37 рассматриваются как протекторы гранулезных кле-ток не только от апоптоза, но и преждевременной лю-теинизации. В проведенном исследовании экспрес-сия BMP15 и Cx37 в ооцитах вторичных и третичных фолликулов значимо не отличается от таковой в кон-троле, но прогрессивно снижается по сравнению с предыдущими точками опыта (см.…”

“…В течение более полувека было известно, что фолликулогенез регулируется гормонами гипофиза [8], однако только в последнее десятилетие стало очевидным, что гонадотропное действие на яичник опосредуется сигналами внутри гонады (паракрино-вая регуляция) и путем прямой межклеточной связи через щелевые каналы [9]. Взаимодействие ооцита и фолликулоцитов управляет ростом и дифференци-ровкой фолликулов, координируя пути развития обоих типов клеток [10].…”
