Rabbit ductus deferens containing SMA hydrogel. a Longitudinal section (100X magnification) of vas deferens containing hydrogel appearing as eosinophilic homogenous luminal material. Arrowheads depict the mucosal epithelium. Muscularis (M), vas deferens lumen (L). b Longitudinal section (400X magnification) of vas deferens containing hydrogel. Arrowheads depict the attenuated mucosal epithelium in this section. Scattered spermatozoa are present (arrows). Muscularis (M), vas deferens lumen (L). c Cross section (200X magnification) of vas deferens. A layer of epithelioid macrophages replaces the luminal epithelium in this section (). Muscularis (M), vas deferens lumen (L). d Interstitial hydrogel with associated granulomatous inflammation (400X magnification). Arrows depict epithelioid macrophages and multinucleated giant cells surrounding eosinophilic to amphophilic material in the interstitium
