Unique transcriptome analysis of oocytes. A PCA of the transcriptome of RNA-seq data from oocytes at different stages of maturation. oocytes were clustered into three subpopulations corresponding to the maturation stages. B Pearson correlation analysis between samples of oocytes. C Heatmap of differential genes in 3 stages of oocytes. D Enrichment results of transcriptionally active genes in GV, MI, MII 3 periods. E Expression of genes related to mitochondrial translation in GV, MI, and MII stages (gene expression levels in the GV stage were normalized)
