Table 2 The proportion of oocytes (mean ± SD) at GV-arrest, metaphase l or telophase l stages in GV oocytes injected with miR-130b precursor, inhibitor or scramble miRNA and uninjected groups

From: MicroRNA-130b is involved in bovine granulosa and cumulus cells function, oocyte maturation and blastocyst formation
