Figure 8

Confocal images of the cervical region of pregnant guinea pigs treated with hydrogels for 72 h. The hydrogel (green) is seen on the surface of the mucosal layer (red), separated by the mucus coating the epithelium (unlabeled). The nuclei are stained blue with DAPI. SE = subepithelial layer, ML = mucified epithelial layer. The right panel is a higher magnification image of the indicated region of the left panel to further illustrate the mucus layer separating the gel from the epithelium.
