Mir-let-7 family decreases embryo implantation competency. a The increasing level of let-7 g in let-7 g-TG mice embryo after doxycycline fed for 1/2/3/4 days. b The attachment rate of let-7 g-TG mice embryo. c In vitro outgrowth rate of let-7 g-TG mice embryo. d The outgrowth status of let-7 g-TG embryo. e Relative outgrowth area in let-7 g-TG embryo. f, g, h Implantation site of let-7 g overexpressed or control embryo transferred pseudopregnant mice at Day 6. Data are means ± s.d. (N = 3–5), bar = 100 μm, p < 0.05 “*”, p < 0.01 “**”
