Quantitative real-time PCR analysis of miR-181a expression in oocytes and early embryos (mean ± SEM, n = 3). The oocytes and embryo samples in the experiment included GV- and MII-stage oocytes, 2-cell (2C), 4-cell (4C), 8-cell (8C), 16-cell (16C), morula (MO)-stage, and blastocyst (BL)-stage embryos. Quantity of miR-181a was normalized to miR-125b. Different letters indicate statistical difference (P < 0.05).
