Figure 2. Relative abundance of transcripts from different genes of in vivo-matured (IN VIVO-OPU) and in vitro-matured (IN VITRO-Abattoir) bovine oocytes derived from different donors. Transcript level of in vivo-matured oocytes was used as calibrator (relative abundance = 1.00). Data are show as mean ± SEM. (*) Asterisk indicates difference between IN VIVO-OPU and IN VITRO–Abattoir groups (p<0.05)
