Supplemental Figure S1.
A: Cervical epithelial sections in E7/Cre/Pgrf/− mice were stained with hematoxylin and eosin. Note that the epithelium in the disease-free mouse is hypoplastic, unlike a diseased mouse. F288 and F292 are histology sample identifiers. B: The disease-free mouse sample shown in A was stained for progesterone receptor (green). A tissue section from E7/Cre/Pgrf/− mice was used as positive control. Nuclei were counterstained with Hoechst 33258 and pseudocolored red. White lines separate epithelium (ep) and stroma (st). Scale bars: 100 μm (A); 30 μm (B).
