Abstract
The reproductive tract secretes bioactive molecules collectively known as embryokines that can regulate embryonic growth and development. In the present study we tested four growth factors expressed in the endometrium for their ability to modify the development of the bovine embryo to the blastocyst stage and alter the expression of genes found to be upregulated (bone morphogenetic protein 15 (BMP15) and keratin 8, type II (KRT8)) or downregulated (NADH dehydrogenase 1 (ND1) and S100 calcium binding protein A10 (S100A10)) in embryos competent to develop to term. Zygotes were treated at Day 5 with 0.01, 0.1 or 1.0 nM growth factor. The highest concentration of activin A increased the percentage of putative zygotes that developed to the blastocyst stage. Connective tissue growth factor (CTGF) increased the number of cells in the inner cell mass (ICM), decreased the trophectoderm : ICM ratio and increased blastocyst expression of KRT8 and ND1. The lowest concentration of hepatocyte growth factor (HGF) reduced the percentage of putative zygotes becoming blastocysts. Teratocarcinoma-derived growth factor 1 increased total cell number at 0.01 nM and expression of S100A10 at 1.0 nM, but otherwise had no effects. Results confirm the prodevelopmental actions of activin A and indicate that CTGF may also function as an embryokine by regulating the number of ICM cells in the blastocyst and altering gene expression. Low concentrations of HGF were inhibitory to development.

Abstract
INTRODUCTION Hepatocyte growth factor (HGF), also known as scatter factor, and its receptor c-Met have been shown to be implicated in endometriosis. HGF acts as a mitogen, motogen, and morphogen on endometrial epithelial cells. The expression of c-Met on human endometrial cells has been reported. Many proteins are proteolytically released from the surface by a process known as ectodomain shedding. The aim of this study was to determine the levels of soluble c-Met (s-cMet) in the peritoneal fluid (PF) and serum samples of patients with different stages of endometriosis. MATERIAL AND METHODS 39 PF and serum samples from normal healthy and 130 samples from different stages of patients with endometriosis (33 cases of stage I, 38 stage II, 30 stage III and 29 stage IV) were included in this study. Total protein concentration (TPC) and the level of s-cMet in the PF and serum were determined by Bio-Rad protein assay based on the Bradford dye procedure and enzyme-linked immunosorbent assay, respectively. RESULTS No significant change in the TPC was seen in the serum and PF of patients with endometriosis when compared with normal controls. Results obtained demonstrated that all PF and serum samples presented s-cMet expression, whereas, starting from stages I to IV endometriosis, a significant increase of s-cMet expression was observed as compared to controls. CONCLUSION The results of this study show that a high expression of s-cMet is correlated with advanced stages of endometriosis. It is also concluded that the detection of serum and PF s-cMet may be useful in classifying endometriosis.

Abstract
The mucosal immune system in the upper female reproductive tract is uniquely prepared to maintain a balance between the presence of commensal bacteria, sexually transmitted bacterial and viral pathogens, allogeneic spermatozoa, and an immunologically distinct fetus. At the center of this dynamic system are the epithelial cells that line the Fallopian tubes, uterus, cervix and vagina. Epithelial cells provide a first line of defense that confers continuous protection, by providing a physical barrier as well as secretions containing bactericidal and virucidal agents. In addition to maintaining a state of ongoing protection, these cells have evolved to respond to pathogens, in part through Toll-like receptors (TLRs), to enhance innate immune protection and, when necessary, to contribute to the initiation of an adaptive immune response. Against this backdrop, epithelial cell innate and adaptive immune function is modulated to meet the constraints of procreation. The overall goal of this review is to focus on the dynamic role of epithelial cells in the upper reproductive tract, with special emphasis on the uterus, to define the unique properties of these cells as they maintain homeostasis in preparation for successful fertilization and pregnancy while at the same time confer protection against sexually transmitted infections, which threaten to compromise women's reproductive health and survival. By understanding the nature of this protection and the ways in which innate and adaptive immunity are regulated by sex hormones, these studies provide the opportunity to contribute to the foundation of information essential for ensuring reproductive health.

Abstract
Epithelial cell integrity at mucosal surfaces provides an effective physical barrier against potential pathogens that threaten reproductive health. We have used polarized epithelial cells from adult mouse uteri to investigate the roles of TNFalpha and TGFbeta, which are produced by uterine epithelial and stromal cells, and hepatocyte growth factor (HGF), produced by uterine stromal cells, in regulating epithelial cell integrity measured as transepithelial electrical resistance (TER). Exposure of epithelial cells to TNFalpha, TGFbeta, and HGF have profound effects on TER that are different from their known actions on TER at other mucosal surfaces. When incubated with TNFalpha, TER increased in a dose-dependent manner. In contrast, when cells were incubated with TGFbeta, TER was markedly but reversibly suppressed. Interestingly, HGF, when placed in the basolateral compartment, increased TER. Based on these findings, we conclude that TNFalpha, TGFbeta and HGF may play regulatory roles in modulating epithelial cell tight junctions. These studies suggest that factors, such as hormone balance, pathogen exposure as well as pregnancy, which affect cytokine and growth factor secretion, influence epithelial cell barrier protection within the female reproductive tract.

Abstract
Hepatocyte growth factor/scatter factor (HGF/SF) is a pleiotropic cytokine that plays a crucial role in the embryonic and postnatal development of various organs including the mammary gland. We cloned bovine HGF and its c-Met receptor cDNAs, and examined their expression during mammary gland development in dairy cows. The 2.5-kbp HGF cDNA clone contained a 2190 bp open reading frame coding a 730 amino acid protein, while the 4.8-kbp c-Met cDNA clone contained a 4152 bp open reading frame coding a 1384 amino acid protein. The bovine HGF and c-Met sequences exhibited more than 87% identity with those of other mammals. RT-PCR analysis revealed ubiquitous expression of both HGF and c-Met mRNAs in various bovine tissues tested. HGF mRNA was detected only in the inactive stage of bovine mammary gland development and not in the developing, lactating, and involuting stages, while c-Met mRNA was detected in the inactive and involuting stages. Immunohistochemical analysis demonstrated that the c-Met protein was found on mammary epithelial cells in the inactive, developing, and involuting stages, and on myoepithelial cells in all stages. These results suggest pivotal roles of HGF and c-Met in the development of bovine mammary gland.

Abstract
To study Ag presentation in the female reproductive tract, DO11.10 TCR transgenic mice specific for the class II MHC-restricted OVA(323-339) peptide and non-transgenic BALB/c mice were used. We report here that freshly isolated uterine epithelial cells, uterine stromal, and vaginal APCs present OVA and OVA(323-339) peptide to naive- and memory T cells, which is reduced when cells are incubated with Abs to CD80 and 86. To determine whether polarized primary epithelial cells present Ags, uterine epithelial cells were cultured on cell inserts in either the upright or inverted position. After reaching confluence, as indicated by high transepithelial resistance (>2000 ohms/well), Ag presentation by epithelial cells incubated with memory T cells and OVA(323-339) peptide placed on the basolateral surface (inverted) was 2- to 3-fold greater than that seen with epithelial cells in contact with T cells and peptide on the apical surface (upright). In contrast, whereas freshly isolated epithelial cells process OVA, polarized epithelial cells did not. When epithelial cells grown upright on inserts were incubated with T cells and OVA(323-339) peptide, coculture with either hepatocyte growth factor or conditioned stromal medium increased epithelial cell Ag presentation (approximately 90% higher than controls). These studies indicate that uterine stromal cells produce a soluble factor(s) in addition to a hepatocyte growth factor, which regulates epithelial cell Ag presentation. Overall, these results demonstrate that polarized epithelial cells are able to present Ags and suggest that uterine stromal cells communicate with epithelial cells via a soluble factor(s) to regulate Ag presentation in the uterus.

Abstract
Underlying stromal cells are essential for the normal development of epithelial cells (ECs) at mucosal surfaces. Recent studies from our laboratory have shown that uterine stromal cells regulate EC integrity, measured as transepithelial resistance (TER) as well as tumor necrosis factor (TNF) alpha alpha secretion by ECs in culture. Using stromal cells in coculture with polarized ECs grown on inserts, we found that stromal cells produce soluble mediators that increase TER and decrease TNFalpha secretion. The purpose of the present study was to identify the mechanisms whereby stromal cells exert their effects on uterine epithelium. We report that hepatocyte growth factor (HGF), a known mesenchymal growth factor that mediates EC proliferation, increases TER but, at the same time, decreases apical TNFalpha release. When ECs and/or stromal cells were incubated with anti-HGF or anti-HGF receptor (HGFR) antibody before HGF, the effects of HGF were blocked. These findings indicate that ECs express the HGFR at their basolateral surfaces and that HGFR mediates the effects of HGF on TER and TNFalpha. Neutralization of stromal cell secretions with antibodies for HGF and HGFR demonstrate that stromal-derived HGF is the mediator of EC TER. In contrast, neither anti-HGF antibody nor HGFR antibody had any effect on stromal cell-induced decreases in TNFalpha secretion. From these results, we conclude that stromal cell regulation of EC TER is mediated through the secretion of stromal HGF. Furthermore, because neutralization of stromal media failed to affect TNFalpha secretion, these findings suggest that other growth factors, in addition to HGF, affect EC cytokine production.

Abstract
The oviductal epithelium consists of two major cell populations, secretory cells and cilial cells. In a previous report, we established clonal cell lines from the epithelium and stroma of an oviduct which allowed us to analyze stromal contribution to epithelial functions. Three stromal cell lines were co-cultured in separated apparatus with 3 epithelial cell lines, respectively. Two stromal cell lines preferentially stimulated mogp-1 expression on secretory cells and the stimulation was additive with estrogen. The lines had no effect on cilial cells. One stromal cell line preferentially stimulated foxj1 expression on cilial cells and the stimulation relieved suppression by estrogen. The line had no effect on secretory cells. Experiments with conditioned media of the stromal cells confirmed the results of co-culture experiments, suggesting that the oviductal stroma contains multiple cell populations preferentially regulating or modulating specific cell populations of the epithelium via diffusible factors.

Abstract
Tumor necrosis factor-alpha (TNFalpha) has been shown to be a potent stimulator of prostaglandin (PG) F2alpha synthesis in bovine endometrial stromal cells. The aims of the present study were to determine the effect of interferon-tau (IFNtau) on TNFalpha-stimulated PGF2alpha synthesis and the intracellular mechanisms of TNFalpha and IFNtau action in the stromal cells. When cultured bovine stromal cells were exposed to TNFalpha (0.006-0.6 nM) for 24 h, the production of PGF2alpha and cyclooxygenase (COX)-2 gene expression were stimulated by TNFalpha (0.06-0.6 nM, P < 0.05). Moreover, a specific COX-2 inhibitor (NS-398; 5 nM) blocked the stimulatory effect of TNFalpha on PGF2alpha production (P < 0.05). Although IFNtau (0.03-30 ng/ml) did not stimulate basal PGF2alpha production in the stromal cells, it suppressed TNFalpha action in PGF2alpha production dose dependently (P < 0.05). Moreover, the stimulatory effect of TNFalpha (0.6 nM) on COX-2 gene expression was completely blocked by IFNtau (30 ng/ml; P < 0.05), although the gene expression of COX-2 was not influenced by IFNtau. The overall results indicate that the stimulatory effect of TNFalpha on PGF2alpha production is mediated by the up-regulation of COX-2 gene expression and suggest that one of the mechanisms of the inhibitory effect of IFNtau on luteolysis is the inhibition of TNFalpha action in PGF2alpha production in the stromal cells by the down-regulation of COX-2 gene expression stimulated by TNFalpha.
