| 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... |

| This study examined the fine structures of epididymal spermatozoa on the lesser white-toothed shrew ( Crocidura suaveolens ), the Japanese white-toothed shrew ( C. dsinezumi ) and the big white-toothed shrew ( C. lasiura ) belonging to the subfamily Crocidurinae living in Korea . In the spermatozoa of C. suaveolens , the head has a large acrosome, a smooth inner acrosomal membrane and a wavy, finger-like, electron-dense apical body. The neck has a solid proximal centriole that is filled with electron-dense material. These results showed the spermatozoa of C. suaveolens possess the characteristics of both Crocidurinae and Soricinae. In C. dsinezumi and C. lasiura , the head has a large acrosome, a serrated inner acrosomal membrane and a common apical body.... |
