Differential co-expression in oocytes and surrounding cumulus cells classified by BCB staining. A Genes significantly co-expressed in BCB positive oocytes and surrounding cumulus cells, comparatively to complex-oocyte complexes obtained from BCB negative oocytes. B Genes significantly co-expressed in BCB negative oocytes and surrounding cumulus cells, comparatively to cumulus-oocyte complexes obtained from BCB positive oocytes. C Independent clustering of oocytes and cumulus cells using 75 and 108 genes, respectively, co-expressing at r \(\ge\) 0.992. D Connectivity of the genes expressed in oocytes and surrounding cumulus cells co-expressing at r \(\ge\) 0.992. Only genes annotated with a symbol are depicted on panel D
