Morphological Studies And Immunolabeling Of Female Hormonal Receptors In Thai Swamp Buffalo Oviducts At Prepuberty, Paisan Tienthai, Kriengyot Sajjarengpong
The Thai Journal of Veterinary Medicine
The present study aimed to examine the general morphology of Thai swamp buffalo’s oviducts by light microscopy (LM) and scanning electron microscopy (SEM) as well as the expression of estrogen receptor alpha (ERα) and progesterone receptor isoform B (PRB) by immunohistochemical technique at the prepubertal stage. The samples composed of the uterotubal junction (UTJ), isthmus, ampulla and infundibulum of prepubertal Thai swamp buffalo oviducts (n=6) were collected from a local slaughterhouse. The results showed that the epithelium of prepubertal Thai swamp buffalo oviducts was composed of ciliated and secretory cells but the feature of nuclear/cytoplasmic protrusions of secretory cells was …

The objective of this study was to investigate the presence and distribution of the progesterone receptor (PR) in the Thai swamp buffalo oviduct at the follicular (n=10) and luteal phases (n=12). Reproductive tracts from mature female Thai swamp buffaloes were collected from a local slaughterhouse. Both ovaries were examined for the phase of estrous cycle and the oviducts were separated into the uterotubal junction (UTJ), the isthmus, the ampulla and the infundibulum. Tissue samples were subjected to immunohistochemical staining to assess the localization of PR in the epithelium, subepithelial connective tissue and smooth muscle. A positive nuclear immunolabeling of PR …
