“…Others considered them to be similar to lymphocytes that have migrated into the epithelium from the underlying connective tissue [Nellor, 1965;Odor, 1974;DuBois et al, 1980]. Rasweiler [1972] identified the basal cells in the epithelium of the bat uterine tube as mast cells on the basis of both their staining reactions and the presence of pseudopodia similar to those of mast cells in the lamina propria. None of the basal cells in the present Abughrien/Dore/McGeady/ Fitzpatrick Fig.…”

“…Other investigators have proposed that the basal or indifferent cell represents a reserve or stem cell which gives rise to ciliated and secretory cells of the tubal epithelium [Pauerstein and Woodruff, 1967;Bulló n et al, 1980]. In addition it has been proposed that basal cells arise primarily from connective tissue mast cells which migrate into the epithelium and undergo degranulation [Rasweiler, 1972].…”

The epithelium of the uterine tube consists of ciliated cells and secretory cells. Basal cells are a third cell type observed in tubal epithelium and they are located principally in the basal part of the epithelium. The objectives of this study were to characterize these basal cells in normal and superovulated heifers and to determine whether they participate in the replacement of the ciliated and secretory cell populations. All heifers received cloprostenol (PG) to induce oestrus (day 0). Superovulated heifers received 24 mg pFSH at doses of 4.5, 3.5, 2.5 and 1.5 mg given twice daily. Control and superovulated heifers were slaughtered on days 1, 3, 5 and 7 of the oestrous cycle. Another group of normal cycling heifers was slaughtered on days 2–3 and 11–13 of the oestrous cycle and used for immunocytochemistry. Samples from ampulla, pre-isthmus and isthmus of the uterine tube were collected and processed for light and transmission electron microscopy. Quantitative examination by light microscopy showed that there was a significant difference in the number of basal cells between the regions of the heifers’ uterine tube. On the basis of ultrastructure two populations of basal cells were observed. One (type I) had a nucleus with much condensed heterochromatin and very sparse cytoplasmic organelles. The second cell (type II) had a nucleus with heterochromatin typically clumped around the nuclear envelope. Its cytoplasm contained many organelles including a number of lysosomes. The ultrastructural features of these cells were similar in all regions and at all days of the oestrous cycle examined. Immunocytochemistry revealed that type I basal cells were lymphocytes and type II basal cells were macrophages.

“…Intracytoplasmic ciliated cysts have been described in the oviduct epithelium of a number of vertebrates including the rat, guinea pig, hamster, rabbit, cat, dog, hog, sheep, cow, horse, bat and human (MIHALIK, 1934;FLERKO, 1955;OVERBECK 1967;RASWEILER, 1972;KRAUS et al, 1974;JIRSOVA et al, 1977;BERNHARDT-HUTH et al, 1979;HAGIWARA et al, 1990;ODOR, 1991). Besides cilia and microvilli, various-shaped dense bodies and a finely granular amorphous material were commonly found in the cyst lumen.…”

“…The amorphous material was well contrasted with periodic acid-thiocarbohydrazide-silver proteinate staining (YOSHIMI et al, 1991), indicating that the material was composed of glycoprotein. The cyst has also been known to be positive in the periodic-Schiff reaction and to be diastase resistant (RASWEILER, 1972). The light microscopic findings that ciliated cysts were seen in different positions in the rabbit and human oviduct epithelia led to the idea that they arise basally in the epithelium, migrate to the apical cell surface, and serve in the formation of the apical ciliated border by opening onto the surface (MIHALIK, 1934).…”

“…The cysts have been described under physiological conditions in the ciliated epithelium of the oviduct of various mammals, including man (MIHALIK, 1934;FLERKO, 1955;OVERBECK, 1967;RASWEILER, 1972;KRAUS et al, 1974;JIRSOVA et al, 1977;HAGIWARA et al, 1990;ODOR, 1991). Some light microscopists, who investigated the cysts in the oviductal and endometrial epithelia, have ascribed to them a particular role in the formation of the ciliated border, as they recognized the opening of the cysts onto the apical cell surface (MIHALIK, 1934;HAMPERL, 1950;FLERKO, 1955).…”

Early development of the bat, Glossophaga soricina, was investigated histologically using 71 pregnant animals removed from a laboratory colony at timed intervals after mating.Implantation was initiated between days 12 and 14 post-coitum, i.e., shortly after entrance of the blastocyst into the simplex uterus. The site of implantation was a narrow, tubular segment, the intramural uterine cornu, interposed between the end of the oviduct and the main uterine cavity. The intramural uterine comu is probably homologous to the cranial end of a horn in a bicornuate uterus. Attachment of the blastocyst was central and circumferential, and orientation of the inner cell mass was cephalad in line with the long axis of the comu. Implantation was secondarily interstitial in the fundal endometrium, as the lumen of the intramural uterine cornu was obliterated and the decidua filled in around the expanding blastocyst.The yolk sac was formed between days 15 and 24 by the expansion and coalescence of pockets within a meshwork of endoderm. Endoderm completely surrounded the inner cell mass until the onset of amniogenesis and served to suspend the inner cell mass from the cytotrophoblast. A decidual reaction first appeared on day 15 after trophoblastic penetration to the endometrial stroma. Syncytiotrophoblast developed as engulfment of maternal capillaries began on day 16, and the capillary endothelium was rapidly disrupted. Amniogenesis occurred by cavitation, beginning on day 26, and shield formation was complete in some animals by day 32.
