The current investigation was carried out on the seminal glands of six apparently healthy mature male Buffalo bulls and six immature. The specimens were collected and examined anatomically and histologically after being fixed in 10% buffered neutral formalin. The specimens were subjected to processing till paraffin sections were obtained and stained. The anatomical and histological findings of the seminal glands are varying with age. Anatomically, the immature seminal gland was small sized, flaccid in texture, white in color and measured about 0.80-0.95 gm in weight, 1.95-2.50 cm in length, 1.00-1.15 cm in width and about 0.46-0.60 cm in thickness. Meanwhile, in mature one became larger in size, firm in texture, pale yellow in color, multi-lobulated where had a very large lobules on its outer surface giving, cluster of grapes liked appearance. It measured about 7-8 gm in weight, 5-6 cm in length, 2-2.5 cm in width and about 80-1.3 cm in thickness. Microscopically, the seminal gland was observed consisting of a stroma of connective tissue and a parenchyma of differentiating and undifferentiating acini in immature animal. Meanwhile, in mature one, the parenchyma was consisted of secretory end pieces and well-developed duct system. With advancement of age, the thickness of the capsule and trabeculae increased, also the number of secretory end pieces per unite area increased and the amount of inter-glandular connective tissue stroma reduced.

Moreover, 4 types of cells were identified; columnar, basal, dense and clear cells in boar (Badia et al, 2006). Some of columnar cells possess light, bleb-like apical projections that were supported by report of Eurell and Frappier (2006) that indicate apocrine mode of secretion (Archana et al, 2009).…”

The present study was investigated the histological structure of the vesicular glands of eight mature castrated and noncastrated zaraibi bucks (4 animals/ each group). Generally, the vesicular gland of bucks was compact and lobulated gland. It was covered by a muscular capsule sending fibro-muscular septa dividing the gland into irregular unequal lobules. Each lobule was formed of numerous secretory acini and few amount of inter-acinar connective tissue stroma. Each lobule had a central collecting sinus to collect the secretions from the different acini. Both secretory acini and central collecting sinuses were lined mainly with pseudostratified columnar epithelium that was consisted mainly of secretory columnar cells and few small basal cells. The secretion was released into the acinar limen via apocrine mode. The castrated bucks showed more connective tissue and less acinar components in comparison to non-castrated bucks. Such finding represents the histological difference between the vesicular gland of castrated and non-castrated bucks that pointed out the effect of castration on structure of the vesicular gland.

“…There is also distension of the ER and Golgi apparatus and pockets of less electron-dense cells throughout the epithelial lining in 2-mo-old mice. These cells may represent clear cells that have been previously characterized in boar seminal vesicles, and are believed to represent new epithelial cells that have not fully differentiated [34]. Interestingly, at later time points, we observed a larger number of densely stained cells, which are believed to represent older degenerating cells.…”

“…As observed in other serous-secreting cell types, the expression of BHLHB8 is maintained at high levels throughout adulthood, possibly suggesting a role for BHLHB8 in stabilizing the mature phenotype. In addition, BHLHB8 is expressed throughout the entire epithelial layer, so it is unlikely to correlate to the different columnar cells previously described by Badia et al [34].…”

The seminal vesicle is a male accessory sex organ that develops from segments of the Wolffian duct adjacent to the urogenital sinus. It produces most of the seminal plasma in both humans and rodents. To date, very few transcription factors have been linked to the development and differentiation of seminal vesicles. In this study, we have examined the role of basic helix-loop-helix (BHLH) B8 transcription factor expressed at high levels in the adult seminal vesicle and during seminal gland differentiation. Immunofluorescent studies indicate that BHLHB8 is expressed within the epithelial layer of the seminal layer of the seminal vesicle following branching morphogenesis but prior to full maturation of cell morphology and function. Analysis of mice that do not express BHLHB8 (Bhlhb8(-/-)) indicates no deficiency in the initial development of the seminal vesicle. However, morphological and ultrastructural analysis indicates disruption of the epithelial cellular architecture. The seminal vesicle epithelial layer of 2-mo-old Bhlhb8(-/-) mice shows extensive cellular degeneration based on the appearance of reduced microvilli, altered granule size, and dilated endoplasmic reticulum and Golgi apparatus. The seminal vesicle epithelial cells also degenerate prematurely, as evidenced by disruption of nuclear architecture and significant accumulations of autophagic bodies. These results identify BHLHB8 as a regulator in establishing and stabilizing the secreting epithelial cells of the seminal vesicle.
