Exosomes have the ability to carry a wide range of chemicals, convey them to target cells or target regions, and act as “messengers.” For the purpose of investigating embryo attachment, it is helpful to comprehend the range of exosomal mRNAs and miRNAs derived from the uterine flushing fluid before and after embryo attachment. In this study, we recovered exosomes from goat uterine rinsing fluid at 5, 15, and 18 days of gestation and used RNA-Seq to identify the mRNA and miRNA profiles of exosomes obtained from uterine rinsing fluid before and after embryo implantation. In total, 91 differently expressed miRNAs and 27,487 differentially expressed mRNAs were found. The target genes predicted by the differentially expressed miRNAs and the differentially expressed mRNAs were mainly membrane-related organelles with catalytic activity, binding activity, transcriptional regulation activity, and involved in metabolism, biological regulation, development, and other processes. This was revealed by GO analysis. Furthermore, KEGG analysis revealed that they were abundant in signaling pathways associated with embryo implantation, including the “PI3K-Akt signaling pathway,” “Toll-like receptor signaling pathway,” “TGF-beta signaling route,” “Notch signaling pathway,” and others. Moreover, our research has demonstrated, for the first time, that chi-let-7b-5p specifically targets the 3’UTR of CXCL10. Our research offers a fresh viewpoint on the mechanics of embryo attachment.
