| Abstract | ||||
| This work aimed to study the regional distribution pattern of some biologically active proteins of the epididymal duct of donkey through application of immune-histochemistry (IHC). Paraffin-embedded sections from different regions of the epididymal duct were used. Primary antibodies against S100, angiotensinconverting enzyme (ACE), galactosyl- transferase (GalTase), vascular endo-thelial growth factor (VEGF), α-smoothmuscle actin (α-SMA) and connexin 43(Cx43) were used. The immunehistochemical findings exhibited a regional-specific, distribution pattern; different from other domestic mammals. Apical cells in the epididymal epithelium ex- pressed a moderate to strong immune-staining with all of S100, ACE and Gal-Tase. Basal cells exhibited mode-rate to strong immunoreaction with both of GalTase and VEGF. | ||||
