From: Natriuretic peptides improve the developmental competence of in vitro cultured porcine oocytes
The relationship between natriuretic peptides levels and oocyte development potential in follicles sized from 3.0 to 8.0 mm. a, b, c, d The relative expressions of NPPA, NPPB, NPPC and NPR2 genes in porcine cumulus and granulosa cells from different sized follicles. The data are the mean ± SEM and are normalized against the CYC-A gene, with results expressed relative to the control sample using the 2-ΔΔ Ct method with efficiency correction. Different columns with various superscript letters differ significantly (P < 0.05)
