Treatment groups	No. of oocytes	First polar body extrusion (%)
miR-130b precursor	356	86.6 ± 3.7^a
miR-130b inhibitor	489	72.8 ± 5.9^b
Scrambled	488	83.9 ± 3.5^{a, c}
Uninjected	396	80.1 ± 4.0^c

Different letters of superscripts in the same column indicate significant difference (P ≤ 0.05) between treatment groups. GV Germinal vesicle, SD standard deviation
