Research overview
This study reveals that embryo-derived exosomes may carry specific microRNAs that impair endometrial receptivity. Our findings suggest that exosomal miR-143-3p acts as a negative regulator of decidualization via the Kirsten rat sarcoma viral oncogene homolog-extracellular regulated protein kinase/protein kinase B axis and may serve as a promising biomarker for the non-invasive assessment of embryo implantation potential.
Key findings
In brief: Aberrant embryo-maternal cross-talk is a potential cause of in vitro fertilization failure.
This study reveals that embryo-derived exosomes may carry specific microRNAs that impair endometrial receptivity.
Abstract: Despite morphological selection, ∼40% of transferable embryos fail to implant during in vitro fertilization, potentially due to aberrant embryo-maternal cross-talk.
Pre-implantation embryos release extracellular vesicles into their microenvironment, which may participate in embryo-maternal communication.
