In modern-day life, infertility is one of the major issues that can affect an individual, both physically and psychologically. Several anatomical, physiological, and genetic factors might contribute to the infertility of an individual. Intercellular communication between trophectoderm and endometrial epithelium triggers successful embryo implantation and thereby establishes pregnancy. Recent studies demonstrate that Extracellular vesicles (EVs) are emerging as one of the crucial components that are involved in embryo-maternal communication and promote pregnancy. Membrane-bound EVs release several secreted factors within the uterine fluid, which mediates an intermolecular transfer of EVs’ cargos between blastocysts and endometrium. Emerging evidences indicate that several events like imbalance in the release of endometrial or placenta-derived EVs (exosomes/MVs), uptake of their content, failure of embryo selection might lead to implantation failure. Here in this review, we have discussed the current knowledge of the involvement of EVs in maternal-fetal communications during implantation and also highlighted the EVs’ rejuvenating ability to overcome infertility-related issues. We also discussed the alteration of the EVs’ cargo in different pathological conditions that lead to infertility. Therefore, this review would give a better understanding of EVs’ contribution in successful embryo implantation, which could help in the development of new diagnostic tools and cell-free biologics to improve the in vivo reproductive process and to treat infertility by restoring normal reproductive functions.

细胞外囊泡:怀孕期间胚胎-母体串扰的介质和对抗不孕症的新武器

在现代生活中,不孕症是影响个人身体和心理的主要问题之一。几个解剖、生理和遗传因素可能导致个体不育。滋养外胚层和子宫内膜上皮之间的细胞间通讯触发成功的胚胎植入,从而建立妊娠。最近的研究表明,细胞外囊泡 (EVs) 正在成为参与胚胎 - 母体交流和促进怀孕的关键组成部分之一。膜结合 EVs 在子宫液中释放几种分泌因子,介导 EVs 货物在囊胚和子宫内膜之间的分子间转移。新出现的证据表明,子宫内膜或胎盘衍生的 EV(外泌体/MV)的释放失衡、其内容物的吸收、胚胎选择的失败等多种事件可能导致植入失败。在这篇综述中,我们讨论了 EV 在植入过程中参与母胎交流的当前知识,并强调了 EV 克服不育相关问题的恢复能力。我们还讨论了在导致不育的不同病理条件下 EV 的货物的改变。因此,本综述将更好地了解 EVs 在成功胚胎植入中的贡献,这有助于开发新的诊断工具和无细胞生物制剂,以改善胚胎移植。胚胎选择失败可能导致着床失败。在这篇综述中,我们讨论了 EV 在植入过程中参与母胎交流的当前知识,并强调了 EV 克服不育相关问题的恢复能力。我们还讨论了在导致不育的不同病理条件下 EV 货物的改变。因此,本综述将更好地了解 EVs 在成功胚胎植入中的贡献,这有助于开发新的诊断工具和无细胞生物制剂,以改善胚胎移植。胚胎选择失败可能导致植入失败。在这篇综述中,我们讨论了 EV 在植入过程中参与母胎交流的当前知识,并强调了 EV 克服不育相关问题的恢复能力。我们还讨论了在导致不育的不同病理条件下 EV 的货物的改变。因此,本综述将更好地了解 EVs 在成功胚胎植入中的贡献,这有助于开发新的诊断工具和无细胞生物制剂,以改善 我们已经讨论了 EV 在植入过程中参与母胎交流的当前知识,并强调了 EV 克服不育相关问题的恢复能力。我们还讨论了在导致不育的不同病理条件下 EV 的货物的改变。因此,本综述将更好地了解 EVs 在成功胚胎植入中的贡献,这有助于开发新的诊断工具和无细胞生物制剂,以改善胚胎移植。我们已经讨论了 EV 在植入过程中参与母胎交流的当前知识,并强调了 EV 克服不育相关问题的恢复能力。我们还讨论了在导致不育的不同病理条件下 EV 的货物的改变。因此,本综述将更好地了解 EVs 在成功胚胎植入中的贡献,这有助于开发新的诊断工具和无细胞生物制剂,以改善体内生殖过程,并通过恢复正常的生殖功能来治疗不孕症。
