<i>Arid1a</i>^<i>d/d</i> mice exhibited an altered decidualization.

<p>(A) The ARID1A expression were lower in infertile women with endometriosis (n = 6) compared to women without endometriosis (n = 6). (B) The decidualization is highly induced in <i>Arid1a</i>^<i>f/f</i> mice (a) but not <i>Arid1a</i>^<i>d/d</i> mice. Arrow heads indicate stimulated horns. (b). The uterine weight ratio was significantly decreased in <i>Arid1a</i>^<i>d/d</i> mice as compared to <i>Arid1a</i>^<i>f/f</i> (C) Histology of control and stimulated horn in <i>Arid1a</i>^<i>f/f</i> (a and c) and <i>Arid1a</i>^<i>d/d</i> mice (b and d) at day 5, respectively (D) The expression of decidualization marker genes, <i>Bmp2</i>, <i>Fst</i> and <i>Fkbp5</i> was measured in the uteri of control and stimulated horn. The results represent the mean ± SEM of three independent RNA sets. **, <i>p</i> < 0.01; ***, <i>p</i> < 0.001.
