CB1 and TRPV1 immunoreactivity on day 12 of pregnancy. (A) CB1 expression in decidualized cells in the mesometrial region; note that positive staining was restricted to the edges of mesometrial decidua nearest to the ectoplacental cone, which also is positive for CB1; (B) Expression of CB1 in the endovascular trophoblast cells; (C) Expression of CB1 in the metrial gland. Smooth muscle cells of blood vessels and uNK cells (arrows) are positive; (D) TRPV1 expression in decidualized cells in the mesometrial region in the vicinity of ectoplacental cone, which show some positivity. BV - Blood vessel; EC - Ectoplacental cone; MD - Mesometrial decidua; MG - Metrial gland.
