Some immunohistochemical studies on the epididymal duct in the donkey (Equus asinus) [electronic resource].

Includes references.

This work aimed to study the regional distribution pattern of some biologically active proteins of the epididymal duct of donkey through application of immunehistochemistry (IHC). Paraffin-embedded sections from different regions of the epididymal duct were used. Primary antibodies against 5100, angiotensin converting enzyme (ACE), galactosyltransferase (GalTase), vascular endothelial growth factor (VEGF), a-smooth muscle actin (a-SMA) and connexin 43 (Cx43) were used. The immunehistochemical findings exhibited a regionalspecific, distribution pattern; different from other domestic mammals. Apical cells in the epididymal epithelium ex¬pressed a moderate to strong immunestaining with all of 5100, ACE and GalTase. Basal cells exhibited mode-rate to strong immunoreaction with both of GalTase and VEGF. Keywords Epididymis, Donkey, IHC.
