研究概览
We found that Ywhaz-deficient mouse embryos exhibit elevated oxidative and apoptotic stress, transcriptional signatures of impaired glutathione metabolism, and failure to survive to birth despite normal blastocyst morphology. This work provides mechanistic insight into the maternal redox support system of the oviduct and establishes a foundation for EV-based engineering of next-generation embryo culture strategies.
核心发现
Extracellular vesicles (EVs) in the mammalian oviduct constitute a key maternal regulatory system that maintains redox balance during early embryogenesis, yet their molecular cargo and functional relevance in human embryos remain poorly defined.
Here, we show that human Fallopian tube-derived EVs (oEVs) are rapidly internalized by human preimplantation embryos and improve developmental quality in vitro, increasing high-quality Day 3 embryo formation and blastocyst development.
Label-free proteomics identified 6505 oEV proteins, with metabolic, antioxidant and stress-response pathways strongly enriched.
Cross-reference with four independent datasets revealed a conserved protein subset shared across secretory-phase oviduct fluid, pluripotent stem cell-derived EVs and in-vivo-developed embryos; among these, YWHAZ was prioritized for functional validation because of its abundance in oEVs, its presence across embryo-related datasets, and its known involvement in stress-response pathways.
