Abstract

In clinical infertility practice, one intractable problem is low (or absent) ovarian reserve which in turn reflects the natural oocyte depletion associated with advancing maternal age. The number of available eggs has been generally thought to be finite and strictly limited, an entrenched and largely unchallenged tenet dating back more than 50 years. In the past decade, it has been suggested that renewable ovarian germline stem cells (GSCs) exist in adults, and that such cells may be utilized as an oocyte source for women seeking to extend fertility. Currently, the issue of whether mammalian females possess such a population of renewable GSCs remains unsettled. The topic is complex and even agreement on a definitive approach to verify the process of 'ovarian rescue' or 're-potentiation' has been elusive. Similarities have been noted between wound healing and ovarian tissue repair following capsule rupture at ovulation. In addition, molecular signaling events which might be necessary to reverse the effects of reproductive ageing seem congruent with changes occurring in tissue injury responses elsewhere. Recently, clinical experience with such a technique based on autologous activated platelet-rich plasma (PRP) treatment of the adult human ovary has been reported. This review summarizes the present state of understanding of the interaction of platelet-derived growth factors with adult ovarian tissue, and the outcome of human reproductive potential following PRP treatment.

摘要

在临床不孕不育实践中,一个棘手的问题是卵巢储备功能低下(或缺失),这反过来反映了与母亲年龄增长相关的自然卵母细胞耗竭。人们普遍认为可用卵子的数量是有限的,而且是严格受限的,这一观点可以追溯到 50 多年前,是一个根深蒂固且基本未受到挑战的信条。在过去的十年中,人们已经提出,成人的卵巢生殖细胞(GSCs)存在可再生性,并且这些细胞可能被用作希望延长生育能力的女性的卵母细胞来源。目前,关于哺乳动物女性是否存在这种可再生 GSCs 群体的问题仍未得到解决。这个话题很复杂,甚至对于验证“卵巢挽救”或“再潜能化”过程的明确方法的达成一致意见也难以捉摸。在排卵时卵泡破裂后,卵巢组织修复与伤口愈合之间已经注意到相似之处。此外,似乎与生殖衰老相关的逆转作用所必需的分子信号事件与其他部位组织损伤反应中的变化一致。最近,已经报道了一种基于自体激活血小板丰富血浆(PRP)治疗成年女性卵巢的这种技术的临床经验。本综述总结了目前对血小板衍生生长因子与成年卵巢组织相互作用的理解,并总结了 PRP 治疗后人类生殖潜能的结果。
