Fig. 3. Histological examination of mesometrial and anti-mesometrial decidua of gestation day 11.5 wild-type and Dprp-null mice. Mesometrial (A-C) and anti-mesometrial (D-F) decidua were monitored for DPRP expression in wild-type (+/+) tissues (A,D), and for GFP in DPRP-null (-/-) tissues using anti-GFP (B,E) and fluorescence (C,F). The arrowheads in A-C indicate the location of the mesometrial decidua. Note the minimal GFP expression in the mesometrial decidua of B and C. By contrast, the anti-mesometrial decidual regions appear comparable in wild-type and Dprp-null tissues. Scale bars: 250 µm.
