Fig 8. The expression levels of 15 miRNAs were determined by Stem-loop RT-qPCR.

Note: 18S was used as internal control gene for normalization in our experiments. Values were “means ± SD” in receptive endometrium (n = 9) that were relative to pre-receptive endometrium (n = 9), whose values all were 1 in this manuscript because of the method of 2^-ΔΔCt, ΔΔ Ct = (CT _miRNA − CT _18s) _R − (CT _miRNA − CT _18s) _P.
