The IVF group had a higher (P < 0.01) proportion of embryos with low expression of SOX2, NANOG, and FGF4. In addition, a correlation analysis between the expression levels of each gene in individual embryos demonstrated that the relationship between gene expression differed with respect to IVD and IVF embryos. Our results suggest that the expression profiling of developmentally important genes using IVD embryos as normal controls could be a useful indicator for evaluating the quality of bovine IVF embryos.</p>","PeriodicalId":16942,"journal":{"name":"Journal of Reproduction and Development","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11310381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141296233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
