“…Sequentially the subjacent apical plasmatic membrane internalized those caveolae forming small coated vesicles into the apical cytoplasm, as firstly characterized (Goldstein et al). Moreover, the course of the endocytotic process in paca's vas deferens lining epithelium was characterized by presence of the other subcellular structures interrelated with this process, according to our results, and previous descriptions in principal cells of the excurrent ducts of the testis (Hermo et al, 1994;Orsi et al, 1998Orsi et al, , 1999Domeniconi et al).…”

“…The supranuclear cytoplasm of the epithelium principal cells of Agouti paca vas deferens was marked by a well-developed endocytotic apparatus, with possible occurrence of adsorptive endocytosis and phase-fluid endocytosis, similarly to the same process previous described in other cells (Goldstein et al, 1979), and in principal cells of the vas deferens and ductus epididymis of other laboratory rodents (Hermo & De Melo;Hermo et al,1992Hermo et al, , 1994Orsi et al, 1994Orsi et al, , 1999Domeniconi et al), and in a domestic bird . Endocytotic activities verified in the lining epithelium of the paca's vas deferens had been quite similar to those described for principal cells of the rat vas deferens and also in Sertoli cells of the testis (Clermont, 1993;Hermo et al, 1994).…”

On the other hand, the possible occurrence of autophagic or heterophagic digestive processes in principal cells of the vas deferens in paca could be suggested, based on the observations made in this study, and supported by theoretical data regarding similar processes characterized on the general morphology of the Sertoli cells of the testis (Clermont).…”

“…which has been also analyzed by scanning electron microscopy in the vas deferens of the gerbil . Moreover the vas deferens of mammals, with emphasis on laboratory rodents, plays other roles through the functional activity of epithelial lining cells such as adsorptive endocytosis (or phagocytosis), and phase-fluid endocytosis (or pinocytosis), (Hermo & De Melo, 1987;Clermont, 1993;Hermo et al, 1994;Domeniconi et al, 2007) synthesis and secretion of proteins (Hermo & De Melo;Robaire & Hermo, 1988;Hermo et al, 1994;Orsi et al, 1999;Domeniconi et al), and apocrine secretion (Manin et al, 1995;Orsi et al, 1998).…”

SUMMARY:The surface epithelium of the vas deferens of Agouti paca, a wild and large South American rodent, was basically formed by principal and basal cells being only the principal cells related to endocytosis processes and also secretion taking base on their cytoplasmic ultrastructural features. Principal cell of vas deferens epithelium were characterized mainly by presence of vesicles with several shapes, sizes and internalized content at their apical cytoplasm occurring smaller pits and pale small vesicles seen next to the apical brush border of microvillus. Moreover, coated vesicles, smooth surface vesicles and great vesicles; multivesicular bodies, endosomes and lysosomes were seen. Presence of an apocrine secretory apparatus was also viewed, showing apical cytoplasmic expansions protruding into the vas deferens luminal compartment. The basal flattened cells, without luminal surface contact, occurred next to the basement membrane of the ductus, and did no exhibit special ultrastructural features.

Desmodus rotundus is a vampire bat species that inhabits Latin America. Some basic aspects of this species' biology are still unknown, as the histophysiological characteristics of the male reproductive tract. Our study has focused on its epididymis, which is an important organ for performing a variety of functions, especially the sperm maturation and storage. The aim of this study was to identify principal, narrow, clear, and basal cells using cell-specific markers such as aquaporin 9 (AQP9), vacuolar H-ATPase (V-ATPase), and cytokeratin 5 (KRT5). Principal cells were labeled by AQP9 from initial segment to cauda region in their stereocilia. They were shown with a columnar shape, whereas V-ATPase-rich cells were identified with a goblet-shaped body along the entire epididymis, including the initial segment, which were named as clear cells. Pencil-shaped V-ATPase-rich cells (narrow cells) were not detected in the initial segment of the bat epididymis, unlike in the rodent. Basal cells were labeled by KRT5 and were located at the basal portion of the epithelium forming a dense network. However, no basal cells with a luminal-reaching body extension were observed in the bat epididymis. In summary, epithelial cells were identified by their specific markers in the vampire bat epididymis. Principal and basal cells were labeled by AQP9 and KRT5, respectively. Narrow cells were not observed in the vampire bat epididymis, whereas clear cells were identified by V-ATPase labeling along the entire duct in a goblet-shaped body. In addition, no luminal-reaching basal cells were observed in the vampire bat epididymis.
