Abstract
BACKGROUND Spermatozoa interact with oviduct secretions before fertilization in vivo but the molecular players of this dialog and underlying dynamics remain largely unknown. Our objectives were to identify an exhaustive list of sperm-interacting proteins (SIPs) in the bovine oviduct fluid and to evaluate the impact of the oviduct anatomical region (isthmus vs. ampulla) and time relative to ovulation (pre-ovulatory vs. post-ovulatory) on SIPs number and abundance. METHODS Pools of oviduct fluid (OF) from the pre-ovulatory ampulla, pre-ovulatory isthmus, post-ovulatory ampulla, and post-ovulatory isthmus in the side of ovulation were collected from the slaughterhouse. Frozen-thawed bull sperm were incubated with OF or phosphate-buffered saline (control) for 60 min at 38.5 °C. After protein extraction and digestion, sperm and OF samples were analyzed by nanoLC-MS/MS and label-free protein quantification. RESULTS A quantitative comparison between proteins identified in sperm and OF samples (2333 and 2471 proteins, respectively) allowed for the identification of 245 SIPs. The highest number (187) were found in the pre-ovulatory isthmus, i.e., time and place of the sperm reservoir. In total, 41 SIPs (17%) were differentially abundant between stages in a given region or between regions at a given stage and 76 SIPs (31%) were identified in only one region × stage condition. Functional analysis of SIPs predicted roles in cell response to stress, regulation of cell motility, fertilization, and early embryo development. CONCLUSION This study provides a comprehensive list of SIPs in the bovine oviduct and evidences dynamic spatio-temporal changes in sperm-oviduct interactions around ovulation time. Moreover, these data provide protein candidates to improve sperm conservation and in vitro fertilization media.

Abstract
The interactions between oviductal fluid (OF) proteins and spermatozoa play major roles in sperm selection, storage and capacitation before fertilization. However, only a few sperm-interacting proteins in the OF has been identified and very little is known about the regulation of sperm-oviduct interactions across the estrous cycle. Samples of bovine frozen-thawed sperm from three bulls were incubated with OF at pre-, post-ovulatory stages (Pre-/Post-ov) or luteal phase (LP) of the estrous cycle (7 mg/mL proteins, treated groups) or with a protein-free media (control). The proteomes of sperm cells were assessed by nanoLC-MS/MS and quantified by label-free methods. A total of 27 sperm-interacting proteins originating in the OF were identified. Among those, 14 were detected at all stages, eight at Post-ov and LP and five only at LP. The sperm-interacting proteins detected at all stages or at LP and Post-ov were on average more abundant at LP than at other stages (P < 0.05). At Pre-ov, OVGP1 was the most abundant sperm-interacting protein while at Post-ov, ACTB, HSP27, MYH9, MYH14 and OVGP1 were predominant. Different patterns of abundance of sperm-interacting proteins related to the stage were evidenced, which greatly differed from those previously reported in the bovine OF. In conclusion, this study highlights the important regulations of sperm-oviduct interactions across the estrous cycle and provides new protein candidates that may modulate sperm functions.

Abstract
Female sperm storage is an intriguing adaptation exhibited by a wide array of both vertebrates and invertebrates. The mechanisms underlying female sperm storage have remained elusive. Using the Indian garden lizard Calotes versicolor as a model organism, we investigated the role of low and high molecular weight factors in this phenomenon. Previously, we demonstrated three distinct phases of the reproductive cycle in this animal with live, motile spermatozoa recovered from the uterovaginal region during the reproductive phase. In the present study, we analysed the uterovaginal contents using sodium dodecyl sulfate-polyacrylamide gel electrophoresis and identified an abundant protein band corresponding to ~55 kDa regardless of the phase of the reproductive cycle. Analysis of the purified protein by liquid chromatography-tandem mass spectrometry suggested a unique protein without any homology to the National Center for Biotechnology Information database. Exogenous addition of this protein to washed spermatozoa derived from the epididymis reversibly inhibited sperm motility in a concentration- and time-dependent manner, suggesting it plays a key role in sperm storage. These studies are likely to offer new avenues to unravel the secrets of female sperm storage seen across the animal taxa and may have novel applications not only in reproductive biology, but also in general cell storage and preserving endangered animal species.

Abstract
The oviduct was long considered a largely passive conduit for gametes and embryos. However, an increasing number of studies into oviduct physiology have demonstrated that it specifically and significantly influences gamete interaction, fertilization and early embryo development. While oviduct epithelial cell (OEC) function has been examined during maintenance in conventional tissue culture dishes, cells seeded into these two-dimensional (2-D) conditions suffer a rapid loss of differentiated OEC characteristics, such as ciliation and secretory activity. Recently, three-dimensional (3-D) cell culture systems have been developed that make use of cell inserts to create basolateral and apical medium compartments with a confluent epithelial cell layer at the interface. Using such 3-D culture systems, OECs can be triggered to redevelop typical differentiated cell properties and levels of tissue organization can be developed that are not possible in a 2-D culture. 3-D culture systems can be further refined using new micro-engineering techniques (including microfluidics and 3-D printing) which can be used to produce ‘organs-on-chips’, i.e. live 3-D cultures that bio-mimic the oviduct. In this review, concepts for designing bio-mimic 3-D oviduct cultures are presented. The increased possibilities and concomitant challenges when trying to more closely investigate oviduct physiology, gamete activation, fertilization and embryo production are discussed.

Abstract
The Chinese Meishan pig is prolific breed and it is considered that this pig has a capacity with higher rates of embryonic survival. The oviductal secretory cells may affect the embryonic development and survival. The aim of the present study was to investigate the ultrastructural features of secretory cells in the various regions of the Chinese Meishan pig oviduct during the follicular and luteal phases of the oestrous cycle. In the ampullar secretory cells, numerous secretory granules with moderately electron-dense matrices were present in the supranuclear cytoplasm and exocytosis of secretory granules was observed. The number of secretory granules was dramatically reduced in the ampullar secretory cells in the luteal phase. During the follicular phase in the fimbrial epithelium, the secretory cells contained rough endoplasmic reticulum and Golgi apparatus, but most cells had few small granules. In the luteal phase, the secretory cells in the ampullar and fimbrial epithelia extended beyond the luminal border of the ciliated cells. In the isthmus, many granules were present in the cytoplasm of secretory cells throughout the oestrous cycle, but the number of secretory granules was reduced in the luteal phase. The cytomorphometric data revealed that the height of ciliated cells decreased substantially in the fimbriae and ampulla at the luteal phase, while that of non-ciliated cells was less affected. These results suggest that the drastic reduction of cell height of ciliated cells cause the extrusion of most secretory cells beyond the ciliated cells in the fimbriae and ampulla during the luteal phase. In summary, our ultrastructural observations of Chinese Meishan pig oviduct revealed marked cyclic changes in the ultrastructural features of secretory cells. In particular, the ultrastructural features and the numbers of secretory granules were distinctive for each particular segment. These findings should provide insight into the regional and cellular differences in functions of secretory cells of the Chinese Meishan pig oviduct.

Abstract
Osteopontin (OPN) is a secreted extracellular matrix phosphoprotein identified in various tissues and fluids including those of the male and female reproductive tracts. OPN was previously identified as a 55 kDa high fertility marker in Holstein bull seminal plasma, produced by the ampulla and the vesicular gland. The objectives of this study were to characterize OPN on ejaculated and cauda epididymal sperm using immunofluorescence and western blot analysis, and to assess the role of sperm OPN in fertilization. Solubilized sperm membrane proteins from ejaculated and cauda epididymal sperm were separated by 1D SDS-PAGE, transferred to nitrocellulose, and probed with an antibody to bovine milk OPN. A 35 kDa protein was detected by this antibody in both ejaculated and cauda epididymal sperm membranes. Analyses also recognized OPN at 55 and 25 kDa in cauda epididymal fluid and testicular parenchyma homogenates respectively. Immunofluorescent analysis of ejaculated and cauda epididymal sperm showed OPN localization in a well-defined band in the postacrosomal region of the sperm head and also on the midpiece. Results ofin vitrofertilization experiments showed that sperm treated with an antibody to OPN fertilized fewer oocytes than sperm treated with control medium while increasing incidence of polyspermy, suggesting a role of sperm-associated OPN in fertilization and a block to polyspermy. These studies demonstrate that OPN exists at multiple molecular weight forms in the bull reproductive tract and its presence on ejaculated sperm may signal its importance in fertilization by interacting with integrins or other proteins on the oocyte plasma membrane.

Abstract
The objective of the present study was to characterize and quantify changes in exposed saccharide residues of bovine sperm during capacitation in oviductal fluid (ODF) using flow cytometry (FC). Bovine sperm were incubated with 0% or 50% non-luteal ODF for 30 min or 3.5 h. After incubation, sperm were labelled with 11 fluorescein isothiocyanate-labelled lectins and evaluated for lectin binding with FC. Furthermore, inhibiting sugars were used to determine specificity of lectin binding to oligosaccharides on the sperm surface. After 30 min incubation, there was a 91% decrease in fluorescence intensity of labelled sperm incubated in WGA, a 76% decline for Con A, 75% decline for BS-I and a 36% decline for DBA. These differences remained approximately the same over the 3.5-h incubation. Interestingly, although there was no reduction in UEA-I binding at 30 min, a significant reduction (23%) was observed at 3.5 h. Con A fluorescence was mostly inhibited with either alpha-d-glucose or alpha-d-mannose (86% and 90% respectively). BS-I fluorescence was reduced after prior incubation of the control samples with N-acetyl-galactosamine and galactose by 74% and 80% respectively. After prior incubation with N-acetyl-galactosamine DBA fluorescence reduced by 18% in the control samples. With UEA-I no fluorescence reduction was observed after prior incubation with l-fucose. We have demonstrated that capacitation of bovine sperm in ODF is accompanied by a quantitative reduction in individual lectin binding sites. These modifications may be crucial to the subsequent signalling events involved with sperm-zona binding, zona penetration or interaction with the oolema.

Abstract
The mammalian estrogen induced oviductal glycoprotein (OGP) has been known to associate with capacitated sperm, oocytes and developing embryos. This study aimed to identify the putative binding partner of OGP on gametes using N-terminal peptide of bonnet monkey (Macaca radiata) OGP, Nmon, as bait. A protein(s) of molecular size approximately 54 kDa was detected by far-western blot analysis of detergent solubilized human sperm proteins. MALDI-TOF mass spectra analysis of approximately 54 kDa tryptic peptides gave a significant hit to non-muscle myosin heavy chain. Biochemical characterization of approximately 54 kDa was done with antibodies specific to non-muscle myosin IIA, MYH9. The approximately 54 kDa protein, possible breakdown product of MYH9, immunoreacted with MYH9 antibody in western blot analysis. OGP binding to approximately 54 kDa could also be demonstrated in far-western blot analysis of detergent solubilized human sperm proteins and nuclear matrix intermediate filament (NM-IF) preparations from human sperm and mouse oocytes. Far-western blot analysis of MYH9 enriched by immunoprecipitation identified the native approximately 220 kDa protein as OGP-binding partner. The identical and characteristic immunogold localization pattern of Nmon and MYH9 on sperm NM-IF preparation substantiated these findings. The results suggest that OGP binds to both gametes through its interaction with MYH9 through the non-glycosylated N-terminal conserved region of OGP, spanning the residues 11-137.

Abstract
Oviductins are high-molecular-weight glycoproteins synthesized and secreted by nonciliated oviductal epithelial cells and have been shown to play a role in fertilization and early embryo development. The present study was carried out to examine the in vitro binding capacity of hamster oviductin to homologous sperm and to determine the sites of its localization in untreated, capacitated, and acrosome-reacted spermatozoa. Freshly prepared epididymal and capacitated sperm as well as acrosome-reacted sperm were incubated with oviductal fluid prepared from isolated hamster oviducts, fixed and then probed with a monoclonal antibody against hamster oviductin. Results obtained with pre-embedding immunolabeling experiments revealed binding of oviductin to the acrosomal cap and the apical aspect of the postacrosomal region. Immunolabeling of both regions appeared to be more intense in capacitated spermatozoa. Acrosome-reacted sperm showed an immunoreaction of moderate intensity over the postacrosomal region. The plasma membrane overlying the equatorial segment also exhibited a weak labeling. Quantitative analysis obtained with the surface replica technique indicated that oviductin had a higher binding affinity for the acrosomal cap than the postacrosomal region and that the binding of oviductin to the latter plasma membrane domain was enhanced during capacitation. Binding of oviductin to the postacrosomal region, however, was attenuated after acrosome reaction. Immunolabeling for oviductin was found to be the weakest over the equatorial segment regardless of the experimental conditions. The binding of hamster oviductin to specific membrane domains of the homologous sperm and the changes in its distribution during capacitation and acrosome reaction may be important for the function of hamster oviductin preceding and during fertilization.

Abstract
The oviduct is a dynamic organ which facilitates gamete function, fertilization and embryo development. Secretions of the oviduct, recovered by tissue culture or cannulation techniques have been used to define the composition of the oviduct milieu, as well as functions associated with stage of the reproductive cycle or region of the oviduct. Several oviduct proteins have been shown to associate with the gametes and embryos. Ongoing studies are directed at identifying oviduct proteins and determining their function. Oviduct-specific glycoproteins (OSG) have been purified from the oviduct and shown in vitro to have positive affects on sperm capacitation, sperm-ovum binding, ovum penetration and embryo development. Osteopontin, another oviduct secretion, also has been shown to stimulate fertilization and embryo development. The picture emerging is that some components of the oviduct milieu have overlapping functions to collectively provide a failsafe system to ensure fertility in vivo so that success is not dependent on a single component.

Abstract
In the bovine, as in many mammalian species, sperm are temporarily stored in the oviduct before fertilization by binding to the oviduct epithelial cell apical plasma membranes. As the oviduct is able to maintain motility and viability of sperm and modulate capacitation, we propose that proteins present on the apical plasma membrane of oviduct epithelial cells contribute to these effects. To verify this hypothesis, the motility of frozen-thawed sperm was determined after incubation for 6 h with purified apical plasma membranes from fresh or cultured oviduct epithelial cells or from bovine mammary gland cells as a control. Analysis of intracellular calcium levels was performed by flow cytometry on sperm incubated with fresh membranes using Indo-1 to assess the membrane effect on intracellular calcium concentration. The coculture of sperm with fresh and cultured apical membranes maintained initial motility for 6 h (65% and 84%, respectively). This effect was significantly different from control sperm incubated without oviduct epithelial cell apical membranes (23%), with mammary gland cell apical membranes (23%), or with boiled epithelial cell apical membranes (21%). Apical membranes from oviduct epithelial cells diminished the percentage of sperm that reached a lethal calcium concentration over a 4-h period (18.7%) compared with the control (53.8%) and maintained lower intracellular calcium levels in viable sperm. These results show that the apical plasma membrane of bovine oviduct epithelial cells contains anchored proteinic factors that contribute to maintaining motility and viability and possibly to modulating capacitation of bovine sperm.

Abstract
Cryopreservation extends the availability of sperm for fertilization; however, the fertilizing potential of the frozen-thawed sperm is compromised because of alterations in the structure and physiology of the sperm cell. These alterations, characteristics of sperm capacitation, are present in the motile population and decrease sperm life-span, ability to interact with female tract, and fertilizing ability. The etiology of such alterations may represent a combination of factors, such as inherited fragility of the sperm cell to withstand the cryopreservation process and the semen dilution. Although the former is difficult to address, approaches that make-up for the dilution of seminal fluid may be sought. The aim of this work is to review aspects of sperm cryopreservation paralleled by events of capacitation and evaluate the possible roles of sperm membrane cholesterol, reactive oxygen species, and seminal plasma as mediators of cryopreservation effects on sperm function.

Abstract
There is scant information about the storage of spermatozoa within the reproductive tract of the bitch. In several species the uterine tube plays a significant role in sperm storage. The present study was performed to investigate the interaction between spermatozoa and the epithelium of the uterine tube, in particular how this interaction might influence the flagellar activity of spermatozoa in relation to the stage of the estrous cycle. Epithelium was harvested from uterine tubes of 24 bitches at various stages of the estrous cycle (estrus, luteal phase or anestrus), and cultured with pooled spermatozoa collected from 6 dogs. Spermatozoa rapidly bound to the epithelial surface by their heads and the majority of attached spermatozoa were motile. The intimate association between spermatozoa and the uterine tube epithelium maintained motility in a manner that was related to the stage of the estrous cycle. Flagellar activity was significantly greater for spermatozoa bound to estrous epithelium than epithelium from the luteal phase or anestrus. On average, approximately 10% of spermatozoa that were attached to the uterine tube epithelium of estrous bitches retained their flagellar activity for 48 h after innoculation. There was no apparent influence of the region of the uterine tube on this effect. These findings suggest that the uterine tube may form a functional spermatozoal reservoir in the bitch.

Abstract
L-HGP is a highly glycosylated protein from Bufo arenarum egg-jelly coat that diffuses into the surrounding medium when the strings of oocytes are incubated in saline solutions. L-HGP was purified from egg water and the estimated percentage of L-HGP/total protein in egg water was estimated in 30%. In the present study we examine, by indirect immunofluorescence, the effect of L-HGP on acrosome status of homologous spermatozoa. A high percentage (77%) of sperm lost the acrosome when incubated in 10% Ringer solution buffered with 10 mM Tris-HCl, pH 7.6, during 60 min, a condition that resembles egg-jelly osmolarity. The addition of purified L-HGP to the incubation medium prevents acrosome breakdown. The acrosome integrity is maintained for at least 1 hr. This effect is specific for L-HGP at concentration ranging from 0.01 to 0.1 mg/ml since neither BSA nor fetuin seems to have similar activity at similar concentrations. The same effect was observed when spermatozoa were incubated in egg water. Preliminary results suggest that L-HGP binds to B. arenarum spermatozoan membranes.

Abstract
Previously, we identified a 26-kDa fertility-associated protein in bull seminal plasma as lipocalin-type prostaglandin D synthase. The objective of the present study was to immunohistochemically localize this enzyme to the various cell types within the bull testis and seven subsegments of the epididymis, and on ejaculated sperm in order to gain further insight into its potential function in male reproduction. In the testis, immunoperoxidase staining was localized within the elongating spermatids and Sertoli cells of the seminiferous tubules, varying with the stage of the spermatogenic cycle. The highest level of staining occurred during stages III-VII. The cuboidal epithelial cells of the rete testis and efferent ducts were also immunoreactive. Expression of lipocalin-type prostaglandin D synthase was not uniform in the seven epididymal subsegments, suggesting a possible role in sperm maturation. In all epididymal regions, expression was limited to the epithelial principal cells; no immunoreactivity was apparent in other cell types. Lipocalin-type prostaglandin D synthase was strikingly localized in the caput epididymidis, while moderate to weak staining was observed in the remainder of the epididymis. Droplets of reaction product observed within the lumen increased progressively from the caput to cauda. Using fluorescence microscopy, we also localized lipocalin-type prostaglandin D synthase to the apical ridge of the acrosome on ejaculated sperm.

Abstract
Ejaculated sperm collected from 12 beagle dogs were incubated in canine capacitation medium (CCM), supplemented with 5 microg/ml chondroitin sulfate A (CS), 5 microg/ml hyaluronic acid (HA), or 5 microg/ml heparin (HP) for 7 hr at 38 degrees C in a 5% CO2 in air atmosphere to investigate the effects of glycosaminoglycans (GAGs) on dog sperm capacitation. The percentages of motile sperm, hyperactivated sperm (%HY), and acrosome-reacted sperm (%AR) in all media were examined after 4 hr and 7 hr of incubation. The oviducts and uteri of 9 anestrous and 18 estrous beagle bitches were removed under halothane inhalation anesthesia to measure the total GAG amounts in oviductal and uterine fluids. The lumens of the ampulla of the oviducts, isthmus of the oviducts, and the uterine horns were each flushed with 1 ml HEPES-EDTA fluid. Total GAG amounts in the flush fluids obtained were measured with a spectrophotometer. Sperm motility (51-59%), %HY (79-86%), and %AR (31-36%) in CCM supplemented with CS, HA, or HP were significantly higher after 7 hr of incubation than when incubated in CCM without GAGs (P<0.01 or 0.05). The mean total GAG amounts in the fluids from the ampulla and isthmus of the oviducts and the uterine horns in the estrous bitches were higher than in the anestrous bitches. These results indicate that GAGs in the oviductal and uterine fluids in estrous bitches are associated with in vivo sperm capacitation.

Abstract
The effects of bovine oviductal proteins on bull sperm viability, acrosome reaction and motility were studied. Motile frozen/thawed spermatozoa from Percoll gradients were incubated with 1.0 mg/mL oviductal proteins (>8 kDa) extracted by ammonium sulphate precipitation from oviductal extract (OE) or serum-free oviductal epithelial cell-conditioned media (CM), treated in the presence (CM+) or absence (CM-) of 1 microg/mL 17beta-estradiol. Inclusion of oviductal proteins had a significant beneficial effect on sperm viability (76.3 to 80.6%+/-5.3) compared with the control (without oviductal proteins; 57.8%+/-5.3) immediately after the commencement of incubation. After 5 h, viability was significantly higher for CM- and OE treatments than for the control, although no differences were observed at 24 h. Acrosomal status only differed among treatments after 24 h, when higher percentages of acrosome- reacted spermatozoa were found in the control (46.0%+/-2.5) than in the oviductal protein treatments (33.1 to 38.2%+/-2.5). No differences in percentages of motile spermatozoa occurred within the first hour of incubation, although inclusion of CM proteins decreased sperm velocities, beat cross frequency, linearity, and straightness but increased values for mean angular displacement. These findings suggest that proteins secreted by oviductal epithelium promote viability, delay the acrosome reaction and suppress the motion of spermatozoa.

Abstract
The objective of this study was to define the complement of ampullary and isthmic oviductal fluid proteins that associate with the sperm membrane during the non-luteal and luteal stages of the oestrous cycle. Oviductal fluid was obtained from three dairy cows via indwelling cannulae in the ampulla and isthmus of the same oviduct. Daily samples of oviductal fluid were combined by region and stage of the cycle to create pools consisting of non-luteal isthmic, luteal isthmic, non-luteal ampullary, and luteal ampullary oviductal fluid. An aliquot from each oviductal fluid pool was biotinylated by incubation in biotin reagent. Spermatozoa from three fertile bulls were pooled, washed and incubated for 4 h in each of the four pools of biotinylated oviductal fluid. After incubation, sperm membrane proteins were solubilized, and proteins subjected to one-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis and western blotting. The biotinylated oviductal fluid proteins that associated with the sperm membranes were detected by avidin-horseradish peroxidase and diaminobenzidine substrate. Eight oviductal fluid proteins with apparent molecular weights of 97, 75, 66, 55, 48, 34, 28 and 24 kDa were consistently detected to associate with the sperm membrane. Differences in ampullar and isthmic fluid proteins that associated with sperm during the luteal and non-luteal stage of the oestrous cycle were not detected.

Abstract
A bovine oviductal fluid catalase (OFC) which preferentially binds to the acrosome surface of some mammalian spermatozoa has recently been purified. The objectives of this study were to clone the OFC, obtain the full-length cDNA and protein sequence and determine which characteristics of the proteins are associated with the binding of the enzyme to sperm surface. Northern blot analysis revealed low levels of catalase mRNA in bovine oviducts and uterus compared to the liver and kidney. Screening of a cDNA library from the cow oviduct permit to obtain a full-length cDNA of 2282 bp, with an open reading frame of 1581 bp coding for a deduced protein of 526 amino acids (59,789 Da). The deduced protein contained four potential N-glycosylation sites and many potential O-glycosylation sites. The OFC protein exhibited high identity with catalase from other bovine tissues, likewise with catalases from human fibroblast and kidney, and with rat liver catalase. The homology of amino acid sequence of OFC with bovine liver catalase was about 99%. However the OFC possess an extended carboxyl terminus of 20 amino acids not present on the liver catalase. This result is supported by a lower mobility of the OFC compared to the liver catalase when both proteins are submitted on SDS-PAGE.

Abstract
In this communication we approach the events leading to fertilization in mammals by examining the triangle of egg, sperm and oviductal cell taking account of the local physiology and focussing on auto/paracrine interactions. The expression of growth factors and extra-cellular matrix (ECM)-components in bovine ovarian granulosa- and theca-cells, the oocyte-cumulus complex (OOC) and oviductal epithelium, as well as some of the corresponding secreted proteins can be detected through the estrous cycle. Components of the insulin-like (IGF), fibroblast (FGF) and transforming (TGF) growth factor systems, and also metalloproteinase 1 (MMP1) and urokinase (uPA) are found to be modulated in these cells prior to fertilization. Different expression levels between the cell types are found, each representative of a specific reaction window within that particular stage of the cycle. Our findings support the concept that most of the observed tissue in the reproductive tract is dependent upon on the effects of gonadotropins or steroids, but that the fine-regulation is conveyed by, for example, growth factors and ECM-components. We suggest a sophisticated, auto/paracrine and species-specific crosstalk of growth factors and ECM components between the different cell types involved, enabling fertilization and development of the embryo at the right time and in the right location.

Abstract
The only known and measurable difference between X- and Y-chromosome bearing spermatozoa is the small difference in their DNA content. The X sperm in the human carry 2.8% more DNA than the Y sperm, while in domestic livestock this difference ranges from 3.0 to 4.2%. The only successful sperm separation method, flow cytometric sorting, is based on this difference in DNA content. Using this technique, X and Y sperm populations with purities greater than 90% can be obtained. The number of spermatozoa that can be sorted in a given time period, however, is too low for application of this technique in routine artificial insemination. Therefore, the search for a marker other than DNA to differentiate between X and Y sperm remains of interest in order to develop a method for large scale X and Y sperm separation. The aim of the present study was to investigate whether porcine X and Y sperm contain some difference in their plasma membrane proteins. The flow cytometric sorting of sperm enabled a direct comparison of the proteins of the X and Y sperm populations. High resolution two-dimensional (2-D) electrophoresis was used; however, adaptations were needed to enable its use for analysis of proteins of flow cytometrically sorted sperm, both in the sorting procedure, membrane protein solubilization, and in the 2-D electrophoresis. Up to 1000 protein spots per gel could be detected and quantified. Comparison of the 2-D protein patterns revealed differences in protein spots between sperm of two individual boars. However, no differences in protein spots between the X and Y sperm fractions were found. These results provide additional support for the view that X- and Y-chromosome bearing spermatozoa are phenotypically identical, and cast doubt on the likelihood that a surface marker can provide a base for X and Y sperm separation.

Abstract
Changes in the plasma membrane of bovine sperm during heparin-induced capcitation were detected by the binding of fluorescent labeled lectins to unfixed sperm. Of the seven lectins evaluated, only binding of wheat germ agglutinin (WGA) changed with capacitation. Sperm were classified into one of 5 patterns (p1-p5) based on staining with WGA, presence or absence of propidium iodide (PI) staining (dead or alive), and acrosomal integrity (acrosome intact or reacted). The major changes associated with capacitation occurred in p1 and p2. Sperm in p1 exhibited diffuse WGA binding over the anterior sperm head, were alive, and had intact acrosomes. In p2, sperm were also acrosome intact and alive, but lacked WGA binding. When sperm were incubated under capacitating conditions with heparin, there was a decrease over time in the percentage of sperm classified in p1 (p < 0.05) and an increase in the percentage of sperm in p2 (p < 0.05). When capacitation by heparin was delayed by the inclusion of glucose in the culture medium, the same heparin-dependent changes in the percentage of sperm in p1 and p2 were delayed (p < 0.05). When capacitation by heparin was inhibited by including protamine in the culture medium, the percentage of sperm in p1 or p2 was not different from sperm incubated without heparin. Heparin-induced capacitation was associated with a loss of WGA binding to the bovine sperm head.

Abstract
Our laboratory has recently shown that in vitro-cultured oviductal cells secrete sperm motility maintaining factor(s). Since the binding of oviductal proteins to spermatozoa (SPZ) has been demonstrated in many species, the motility factor was postulated to bind the membranes of SPZ. Therefore, the current study was performed to evaluate which proteins from in vivo oviductal secretions bind to sperm membranes, to characterize binding conditions, and to evaluate the effect of this binding on sperm survival. Bovine oviducts were dissected, and oviductal cells and fluid were collected by pressing the oviductal tube with a glass slide. This mixture was incubated in Tris-EDTA buffer at 37 degrees C for 30 min, and the cells were washed twice by centrifugation. The supernatant containing oviductal fluid proteins (OFP) was reserved, filtered, frozen (for later motility tests), or lyophilized and labeled with 125I. Frozen-thawed SPZ were incubated either immediately, following capacitation, ionophore-induced acrosome reaction, death by heating, or flagellar removal with labeled OFP for 30 min. The resulting pellet after three washes was dissolved in SDS and submitted to 10% SDS-PAGE. An autoradiogram showed that 72, 66, 39, 38, and 36 kDa proteins bind strongly to the five types of SPZ used, and that this binding is very specific, since unlabeled OFP inhibited binding while serum proteins did not. Furthermore, for 39, 38, and 36 kDa proteins, the presence of calcium in the incubation medium was essential for dose-dependent binding, whereas magnesium was not. Preincubation of SPZ for 30 min at 37 degrees C with oviductal fluid, followed by one wash and 6 hr of incubation in control media, showed that the percentage of motile SPZ is significantly higher (52 +/- 6%) compared with SPZ not preincubated with oviductal fluid (24 +/- 6%; P < 0.01). In summary, a limited number of proteins from oviductal secretions bind to the surface of bovine SPZ only in the presence of calcium, and this binding appears to be important for subsequent sperm viability.

Data from our laboratory have shown that an estrogen (E2)-dependent M(r) 90,000-92,000 protein and its mRNA are synthesized and expressed in abundant amounts at estrus from the fimbria and ampulla, not isthmus, oviduct of the sheep. Immunocytochemical studies have shown that the M(r) 90,000-92,000 protein is contained in apical secretory granules of oviduct epithelial cells. The objective of this study was to determine whether the mRNA for the E2-dependent oviduct protein was localized and compartmentalized in similar manner. Fimbria, ampulla, and isthmus oviducts obtained from estrous ewes were flash frozen in liquid nitrogen, cryosectioned, fixed in 4% paraformaldehyde, hybridized with digoxigenin (DIG)-labeled oviduct-specific riboprobes, incubated in anti-DIG antibodies conjugated with alkaline phosphatase, and developed in color substrate. Oviduct protein-specific transcripts were localized to basal perinuclear compartments and, surprisingly, at sites distant from the nucleus in the apical cytoplasm of epithelial cells in the fimbria and ampulla. No specific reaction product was observed in the underlying mucosa or smooth muscle layers. Oviduct protein mRNA was contained predominantly in the apical cytoplasm of epithelial cells at the free margins of mucosal folds and in the basal regions of cells located at the crypts of longitudinal folds. No reaction product was present when sections of the fimbria and ampulla oviduct of estrous ewes were incubated in sense riboprobe to the oviduct protein. In addition, when sections of the isthmus oviduct obtained from estrous ewes or fimbira and ampulla oviducts from long-term ovariectomized ewes were hybridized with antisense riboprobes no specific reaction product was detected. Electron microscopy of oviduct protein mRNA containing areas revealed the presence of secretory granules, rough endoplasmic reticulum (RER) and Golgi in the apical cytoplasm, and RER in the basal regions of epithelial cells. These data show that the mRNA encoding an E2-dependent oviduct-specific protein is distributed in epithelial cells at perinuclear foci and at sites distant from the nucleus, which are also the sites of protein localization and protein synthesizing organelles, implying translation at unique cytoplasmic foci.

Abstract
In the cow, a specific glycoprotein--bovine oviduct-specific glycoprotein (BOGP)--is secreted by the epithelial cells of the oviduct at the follicular stage of the estrous cycle. In this study, we examined the effects of purified BOGP on the viability and motility of bovine spermatozoa in culture in vitro. Frozen-thawed bovine spermatozoa were incubated in modified Tyrode's solution (TALP) that contained purified BOGP (TALP-BOGP). In TALP-BOGP, both the viability and motility of bovine spermatozoa were more effectively maintained than in the control medium without any added protein. The increases in both the viability and motility of spermatozoa were dose-dependent. Spermatozoa were also incubated in TALP medium supplemented with bovine serum albumin, egg albumin, lactalbumin, or gastric mucin, and their viability and motility in these media were compared with that in TALP-BOGP. Both the viability and motility of spermatozoa were more effectively maintained in TALP-BOGP throughout a 12-hr incubation than in other media tested. An immunolabeling study demonstrated that a monoclonal antibody specific for BOGP reacted with the posterior region of the head, the middle portion, and the tail of spermatozoa that had been incubated with TALP-BOGP, suggesting that BOGP becomes specifically associated with particular regions of the spermatozoon. These results suggest that BOGP is a potent factor for maintenance of the viability and motility of sperm. On the basis of the present results, we also propose that BOGP may play an important role in sperm functions during the reproductive process.

Abstract
Studies on embryonic development in vitro as well as observations in vivo, suggested that two aspects of oviduct physiology are important for early development. On one side has to be considered the oviduct "environment": temperature, pH, osmotic pressure, nutrients, oxygen tension, free radical scavengers, etc. On the other, the oviduct "active components": stimulatory and/or regulatory molecules, supposed to finely regulate the fertilisation process and the first differentiative steps. While the physical environment of the oviduct has been under investigation for some decades, studies on oviduct-specific molecules and their functions have only been developed much more recently. The amount of information on this topic, however, has rapidly reached the size that demands a summary. In this review the descriptive literature on oviduct specific proteins will be examined as a basis for illustrating the possible functions of these molecules. In particular their role in fertilisation and early embryonic cleavages will be analysed in some details. Finally a section is devoted to the presence and physiological significance of growth factors in oviduct fluid.

Abstract
The major objective of this study was to examine the hormonal regulation of a human oviduct-specific glycoprotein (huOGP) throughout the menstrual cycle and in all regions of the human oviduct. Regulation of synthesis and secretion was examined at both the protein (Western immunoblots and immunocytochemistry) and mRNA (Northern and slot blots) levels and correlated with changes in the morphological features of the oviductal epithelial cells throughout the cycle. Immunoblot analysis of oviductal fluid and explant culture media from all regions of the oviduct demonstrated that huOGP is primarily found during the follicular stage of the cycle and is not present in serum, follicular fluid, or uterine endometrium. Moreover, two-dimensional (2-D) immunoblots showed that all major isoelectric variants of huOGP observed on 2-D fluorographs are immunologically related. Light microscopic immunocytochemistry localized huOGP to oviductal secretory cells in both ampulla and isthmic regions, with the most intense immunoperoxidase staining seen in midcycle samples. Using an indirect immunogold technique at the electron microscopic level, huOGP was specifically localized to secretory granules of the ampullary and isthmic nonciliated epithelial cells. The ultrastructural characteristics of these secretory cells during the mid to late follicular phase of the cycle suggested elevated protein synthetic activity. In addition, mRNA expression for huOGP was elevated in all regions of the oviduct in midcycle specimens. Collectively, these data indicate that huOGP is a major tissue-specific, stage-specific secretory product of the human oviduct during the periovulatory stage of the cycle and support the hypothesis that huOGP synthesis and secretion may be regulated by fluctuations in the levels of estrogen and progesterone.

Abstract
Cultured cells from the bovine endosalpinx were used to evaluate effects of estradiol-17 beta, progesterone, epidermal growth factor, and insulinlike growth factors I and II on [3H]thymidine incorporation. Cells were treated with hormones and growth factors when approximately 50% confluent. After 24 h, DNA synthesis was quantified by pulsing cells with [3H]thymidine for 12 h and determining uptake into DNA. Cells prepared by mechanical dispersal incorporated more [3H]thymidine than cells dispersed with collagenase. However, hormonal responses were the same for both types of cells. As compared to plastic, cells on a Matrigel substratum exhibited lower incorporation of [3H]thymidine and were unresponsive to hormones. Estradiol-17 beta increased [3H]thymidine incorporation slightly at 10(-10) mol/liter and higher. Epidermal growth factor, insulinlike growth factor-I, and insulinlike growth factor-II also stimulated [3H]thymidine incorporation. Effects of insulinlike growth factor-I were greater for cells treated with estradiol-17 beta. In the absence of estradiol, progesterone inhibited [3H]thymidine incorporation at 1, 10, and 100 ng/ml. When estradiol-17 beta was present, progesterone stimulated [3H]thymidine incorporation at 1 ng/ml and reduced incorporation at 100 ng/ml. In conclusion, [3H]thymidine incorporation by cultured oviductal endosalpingeal cells can be regulated by ovarian steroids and growth factors. These molecules may represent signals through which the ovary, embryo, and oviduct regulate oviductal growth.

Abstract
The present study was designed to investigate the possibility that the goat oviduct produces specific substance(s) similar to the oviductal glycoprotein (BOGP) of the bovine oviduct. Oviductal flushings obtained from goats at the follicular and luteal phases of the estrous cycle were examined by immunoblotting for the presence of material that cross-reacted with monoclonal antibodies (MAbs) specific for BOGP. The MAbs immunoreacted with a broad band with a molecular mass of protein of about 97 kDa in the flushings of goat oviducts after fractionation of proteins by electrophoresis under reducing conditions. The antigen was present in flushings obtained from the ampullar segments of oviducts from goats at the follicular stage, but this antigen could hardly be detected in the flushings from the ampulla at the luteal phase and or the flushings from the isthmus at either the follicular or the luteal phase. This antigen was not detected in uterine flushings, follicular fluid, or serum. An immunohistochemical study demonstrated that the MAbs reacted specifically with the epithelial cells of the goat oviduct. Intense labeling was observed in the ampullar and fimbrial epithelia of goat oviducts at the follicular phase, but the immunohistochemical reaction was very weak at the luteal phase. In the isthmus, the reaction was faint during both the follicular and the luteal phase. No specific immunohistochemical reactivity with the MAbs was observed with other tissues from the reproductive tract or with nonreproductive tissues. Immunofluorescent staining showed that the antigen was associated with the zona pellucida of goat ovarian eggs that had been incubated with ampullar flushings from goats at the follicular stage.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A bovine oviduct-specific glycoprotein (BOGP) that sustained the viability of bovine spermatozoa in vitro was purified from an extract of bovine oviducts. The amino-terminal amino acid sequence of BOGP was found to be a homologous with that of oviductin, a protein from hamster that was recently characterized by Mallete and Bleau (1993: Biochem. J. 295, 437-445). Purified BOGP was characterized as a sialo-glycoprotein containing N-linked and O-linked sialo-oligosaccharides side chains with galactose, mannose, N-acetyl-D-galactosamine, N-acetyl-D-glucosamine, fucose and sialic acids in its core protein (57 kDa). Intact BOGP has a wide range of isoelectric points (pIs) from 6.5 to 3.0 but a narrow range of molecular masses around 95 kDa. On isoelectric focusing of neuraminidase-treated BOGP (AS-BOGP), a narrow band with a pI of 9.3 was observed, and the ability of AS-BOGP to maintain sperm viability was negligible. We propose that BOGP is a mucin-type sialo-glycoprotein with a molecular mass of 72 kDa that contains one N-linked and approx. 15 O-linked sialo-oligosaccharide chains. These side chains appear to be important for the maintenance of sperm viability.

Abstract
The objective of this study was to determine if human oviduct specific glycoprotein (huOGP) would associate with hamster ovarian oocytes and human sperm during in vitro incubation. The huOGP used in these studies was partially purified from human hydrosalpinx fluid. Hamster ovarian oocytes and human sperm samples were incubated in culture medium with and without huOGP. Association of huOGP was assessed by indirect immunofluorescence assay using a polyclonal antibody prepared against huOGP. Intense fluorescence of the zona pellucida, and bright but uneven fluorescence of the perivitelline space, were observed in hamster ovarian oocytes following incubation in the presence of huOGP. A similar but more uniform pattern of fluorescence was observed when hamster oviductal oocytes (positive controls) were incubated in culture medium alone. Fluorescence was absent when oocytes were assayed with preimmune serum. The association of huOGP with the zona pellucida and perivitelline space appeared to be specific since thyroglobulin, a large molecular weight glycoprotein, and human serum albumin, the major protein in oviduct fluid, did not associate with the hamster oocytes nor inhibit huOGP association when included in the culture medium. Fluorescence was absent when human sperm incubated with huOGP were assayed with antiserum to huOGP. However, human sperm fluoresced when incubated with a uterine glycoprotein, CUPED, which had previously been shown to bind to cat sperm during in vitro incubation. Sperm also fluoresced brightly when human sperm antibody was used as a positive control. Solubilization of sperm membrane proteins postincubation and analysis of these proteins by 1-D SDS-PAGE followed by immunoblotting also failed to show an association of huOGP with human sperm. Electron microscopy of sperm both pre- and postsolubilization confirmed that the sperm membranes were removed by this process. In conclusion, the association of huOGP with hamster oocytes in vitro suggests that huOGP may associate with human oocytes in vivo, whereas that may not be true for human sperm in vivo. The association of huOGP with oocytes may serve to facilitate the process of fertilization and early embryonic development within the oviduct.
