FIG. 6.

FSHR expression in human placenta and associated tissues at 8–10 wk gestation. Tissues were stained with antibody FSHR-323 IgG2a (brown) and counterstained with hematoxylin (blue). A) Chorionic villi (magnification ×200). Labeled are endothelial cells of developing chorionic villi vessels (V), the chorionic stromal core (S), and trophoblasts (arrowheads labeled T). B and C) Maternal decidua (magnifications ×100 [B] and ×200 [C]). Labeled are decidua (D), maternal vessels (MV), maternal lacunae (ML), and chorionic villi (C). Extravillous trophoblasts are labeled EVT in C. Corresponding negative controls stained with nonimmune IgG2a at the same concentration are shown in Supplemental Figure S7.
