Abstract
Cell lines of turkey sperm storage tubule (SST) epithelial cells were established. Turkey SSTs were dissected from freshly obtained uterovaginal junction (UVJ) tissue and placed in explant culture on various substrates and media. Primary cultures of SST epithelium only survived and grew from SST explants that were cultured on inactivated Sandoz inbred strain, thioguanine- and ouabain-resistance (STO) mouse feeder-cell layers in 12% fetal bovine serum-supplemented Dulbecco's Modified Eagle Medium mixed 1:1 with F12 nutrient mixture. Three independent primary colonies gave rise to 3 finite cell lines, SST-1, -2, and -3, which were continuously cultured for 8 to 16 passages at 1:3 passage ratios over a period of 3 to 4 mo. The cells were passaged by pretreatment with Y27632 and dissociation with Accutase. The SST cells grew as tightly knit monolayers on top of the feeder cells at a slow rate (approximately 96 h doubling time) at a medium pH of approximately 6.9. Lipid vacuoles were visible by light microscopy in the cells particularly at the periphery of growth. Transmission electron microscopy revealed the cells to be a polarized epithelium with apical microvilli and to have lateral tight-junction-like unions and associated desmosomes. Numerous secretory vesicles filled the upper portion of the cells’ cytoplasm, and nuclei and other major organelles such as mitochondria, rough endoplasmic reticulum, and Golgi apparatus were distributed somewhat lower in the cytoplasm. The secretory vesicles resembled mucin secretory vesicles. Proteomic analysis by mass spectroscopy of the conditioned medium of the cells, and of the cells themselves, showed the cell lines did not secrete large amounts of any particular protein, and the analysis confirmed their epithelial character. In conclusion, the SST-derived cell lines resembled the mucus-secreting cells found in the epithelium lining the UVJ of the turkey's reproductive tract.

Abstract
Egg borne Salmonella Enteritidis is still a major cause of human food poisoning. Eggs can become internally contaminated following colonization of the hen's oviduct. In this paper we aimed to analyze the role of flagella of Salmonella Enteritidis in colonization of the hen's oviduct. Using a transposon library screen we showed that mutants lacking functional flagella are significantly more efficient in colonizing the hen's oviduct in vivo. A micro-array analysis proved that transcription of a number of flagellar genes is down-regulated inside chicken oviduct cells. Flagella contain flagellin, a pathogen associated molecular pattern known to bind to Toll-like receptor 5, activating a pro-inflammatory cascade. In vitro tests using primary oviduct cells showed that flagellin is not involved in invasion. Using a ligated loop model, a diminished inflammatory reaction was seen in the oviduct resulting from injection of an aflagellated mutant compared to the wild-type. It is hypothesized that Salmonella Enteritidis downregulates flagellar gene expression in the oviduct and consequently prevents a flagellin-induced inflammatory response, thereby increasing its oviduct colonization efficiency.

Abstract
Salmonella enterica serovar Enteritidis has developed the potential to contaminate table eggs internally, by colonization of the chicken reproductive tract and internalization in the forming egg. The serotype Enteritidis has developed mechanisms to colonize the chicken oviduct more successfully than other serotypes. Until now, the strategies exploited by Salmonella Enteritidis to do so have remained largely unknown. For that reason, a microarray-based transposon library screen was used to identify genes that are essential for the persistence of Salmonella Enteritidis inside primary chicken oviduct gland cells in vitro and inside the reproductive tract in vivo. A total of 81 genes with a potential role in persistence in both the oviduct cells and the oviduct tissue were identified. Major groups of importance include the Salmonella pathogenicity islands 1 and 2, genes involved in stress responses, cell wall, and lipopolysaccharide structure, and the region-of-difference genomic islands 9, 21, and 40.

Abstract
Salmonella enterica serovar Enteritidis is the serovar most frequently isolated from chicken eggs. Colonization of the upper oviduct of hens is believed to play an important role in egg contamination. The interaction of S. enteritidis with gland epithelial cells of the isthmus and the magnum was, therefore, studied in vitro and in vivo. In the first experiment, S. enteritidis bacteria were added to confluent monolayers of primary cultures of chicken tubular epithelial cells of the isthmus (ICTEC) or magnum (MCTEC). Intracellular bacteria in ICTEC and MCTEC were confirmed by a gentamicin protection assay. Internalization in the glandular cells was corroborated by confocal scanning microscopy. Although S. enteritidis was able to invade and proliferate intracellularly during 24 h in the cell culture of both segments, this was significantly more so in the ICTEC. In a second experiment, an in vivo loop model was developed for investigation of the invasiveness of S. enteritidis in the oviduct of laying hens. Loops in the isthmus and magnum of laying hens were made under anaesthesia. S. enteritidis was inoculated into each loop. After 1 h, tubular gland cells were isolated from the infected tissue under gentamicin. S. enteritidis invasiveness was measured as the ratio of isolated bacteria per isolated tubular gland cell. This ratio was higher (P < 0.01) in the isthmus (1.3 x 10(-3)) than in the magnum (5.3 x 10(-5)). In a third experiment, laying hens were intravenously infected with 5 x 10(7) cfu S. enteritidis bacteria. The number of intracellular bacteria was counted in the tubular gland cells of the isthmus and magnum after isolation under gentamicin. The ratio of isolated bacteria per isolated tubular gland cell was again significantly higher in the isthmus as compared with in the magnum. In all 3 assays, the tubular gland cells of the isthmus were more heavily invaded than those of the magnum.

Abstract
1. The effects of estrogen, insulin and dexamethasone on the synthesis of egg white proteins were investigated by employing primary cultured oviduct cells of laying Japanese quails. 2. It was demonstrated that oviduct cells require insulin and dexamethasone, besides estrogen, to synthesize and secrete egg white proteins maximally.

Abstract
Primary cell cultures derived from an androgen-dependent mouse mammary carcinoma, the Shionogi SC-115 tumor, display characteristic changes in growth, morphology and protein synthesis according to the presence or absence of testosterone. In the presence of testosterone, cell proliferation was increased and cells formed characteristic clones having no contact inhibition. Ultrastructural studies of cells showed close contacts of plasma membranes having little or no gap between cells. Some cells were related by bridges of extracellular matrix. Testosterone-induced synthesis of several intracellular and secreted proteins was observed after [35S]methionine-labeling of cells, SDS-PAGE and autoradiography, as well as the disappearance of a protein in androgen-treated cells. In the absence of testosterone, cells grow as a monolayer, have contact inhibition and flattened morphology. The ultrastructurally observed cell-to-cell contacts were usually less intimate, showing spaces of irregular width between cells. None of the testosterone-induced proteins were observed in the absence of hormone. The antiandrogen cyproterone acetate, which by itself was inactive, completely suppressed the androgen-induced effects on growth, morphology and specific protein synthesis. Glycosylation of membrane proteins, as measured after labeling of cells with [3H]N-acetyl-D-glucosamine, was increased by approximately 30% in the presence of testosterone. A similar observation was made in situ by autoradiography on intact cells. Finally, we found that culture medium conditioned by testosterone-treated Shionogi cells had significant mitogenic activity on L-929 mouse fibroblasts.

Abstract
A protein kinase activity was copurified with the chick oviduct progesterone receptor. The enzyme is magnesium dependent and can use the B subunit of progesterone receptor or histones as substrates. The physiochemical parameters of the kinase were determined [pI approximately 5.3; Stokes radius approximately 7.2 nm; sedimentation coefficient (S 20,w) approximately 5.6] and compared to those of the purified B subunit. The results were consistent with the presence of an unique enzyme distinct from the receptor itself. The physiological significance of receptor phosphorylation was investigated in oviduct cells grown in primary culture. Cells were labeled with [32P]orthophosphate in presence or absence of progesterone and the receptor components were immunoprecipitated with a specific polyclonal antibody. Although progesterone treatment lead to the attachment of most of the receptor (approximately 80%) to nuclear structures, the 32P-labeled B subunit was only recovered in the cytosol fraction. Different procedures to extract the nuclear receptor did not allow detection of any 32P-labeled form in the nuclear-soluble fractions, suggesting that the B subunit was not further phosphorylated upon the exposure of cells to progesterone.

Abstract
Oviduct cells from estradiol-treated chicks were grown in primary culture. After 3-5 days of culture in medium containing estradiol, 90% of the cellular progesterone binding sites were detected in the cytosol. After exposure to [3H]progesterone at 37 degrees C, 80% of the progesterone binding sites were found in nuclear fractions. Progesterone receptor phosphorylation was assessed after incubating the cells with [32P]orthophosphate. Receptor components were immunoprecipitated with a specific polyclonal antibody (IgG-G3) and analyzed by NaDodSO4/PAGE and autoradiography. In the cytosol, constant amounts of 32P-labeled 110-kDa subunit (the B subunit, one of the progesterone-binding components of the receptor) and of the non-steroid-binding heat shock protein hsp90 were found, whether cells had been exposed to progesterone or not. No 32P-labeled 79-kDa subunit (the A subunit, another progesterone-binding subunit) was detected. Various procedures were used to solubilize nuclear progesterone receptor (0.5 M KCl, micrococcal nuclease, NaDodSO4), and in no case was 32P-labeled B subunit detected in the extracts. However, nonradioactive B subunit was detected by immunoblot in a nuclear KCl extract of progesterone-treated cells. These results suggest that the fraction of the B subunit that becomes strongly attached to nuclear structures is not phosphorylated upon exposure of cells to progesterone.
