Transcriptome landscape of multispecies germinal vesicle (GV) and second meiosis (MII) stage oocytes. A An outline of the experimental workflow for this study, in brief, using comparative transcriptome analysis and weighted gene co-expression network analysis (WGCNA) to characterise transcriptional signatures of bovine egg development. B The circular hierarchical clustering shows the differences between samples of different species; red means cattle, blue means sheep, green means pig and orange means mouse. C-F Hierarchical clustering heatmaps of GV and MII eggs for cattle, sheep, pigs and mice, respectively
