AbstractThe oviduct is a key organ responsible for ultimate oocytes maturation, transport of gametes, sperm capacitation, fertilization, as well as early embryo development. Its innermost layer, oviductal epithelium, represents a highly dynamic structure which undergoes changes in response to different physiological and pathological processes. Previously, the expression profile of genes involved in several important processes in porcine oviductal epithelial cells (OECs) during long-term primary in vitro culture. The present study further characterizes the porcine OECs model using Affymetrix microarray assay and it analyzes gene expression changes observed on the 7th, 15th and 30th day of culture. 25 genes belonging to “coenzyme metabolic process”, “cofactor biosynthetic process” and “cofactor metabolic process” GO BP terms were differentially expressed in culture. The most up-regulated genes were ALDH1L2, P2RX7, PANK1, ACSS2, SCD, AASS and PDK3. In contrast, several genes appeared to be significantly down-regulated, e.g. ACSL4 and HAAO. Considering the biological roles of the most regulated genes, it can be concluded that these changes may indicate the increased metabolic and proliferation activity of studied cells in primary in vitro culture.Running title: Cofactor and coenzyme metabolism in porcine oviductal epithelial cells

Reproductive Events

Oviductal epithelial cells (OECs) actively produce stimulating and protecting factors, favoring survival and viability of gametes and early embryos. The oviduct participates in the initial reproductive events, which strongly depends on adhesion. The analysis of differential gene expression in OECs, during long-term in vitro culture, enables recognition of new molecular markers regulating several processes, including “biological adhesion”. Porcine oviducts were stained with hematoxylin and eosin, as well as with antibodies against epithelial markers. Then, OECs were long-term in vitro cultured and after 24 h, 7, 15, and 30 days of culture were subjected to transcriptomic and proteomic assays. Microarrays were employed to evaluate gene expression, with Matrix-assisted laser desorption/ionization-time of light (MALDI-TOF) mass spectrometry applied to determine the proteome. The results revealed proper morphology of the oviducts and typical epithelial structure of OECs during the culture. From the set of differentially expressed genes (DEGs), we have selected the 130 that encoded proteins detected by MALDI-TOF MS analysis. From this gene pool, 18 significantly enriched gene ontology biological processes (GO BP) terms were extracted. Among them we focused on genes belonging to “biological adhesion” GO BP. It is suggested that increased expression of studied genes can be attributed to the process of intensive secretion of substances that exhibit favorable influence on oviductal environment, which prime gametes adhesion and viability, fertilization, and early embryo journey.

Early Embryo Development

AbstractAn oviduct is an essential organ for gamete transport, oocyte maturation, fertilization, spermatozoon capacitation and early embryo development. The epithelium plays an important role in oviduct functioning. The products of secretory cells provide an optimal environment and influence gamete activities and embryonic development. The oviduct physiology changes during the female cycle, thus, the ratio of the secreted molecules in the oviduct fluid differs between phases. In this study, a differential gene expression in porcine oviduct epithelial cells was examined during the long-term primary in vitro culture. The microarray expression analysis revealed 2552 genes, 1537 of which were upregulated and 995 were downregulated after 7 days of culture, with subsequent changes in expression during 30 day-long culture. The obtained genes were classified into 8 GO BP terms, connected with angiogenesis and circulatory system development, extracted by DAVID software. Among all genes, 10 most up-regulated and 10 most down-regulated genes were selected for further investigation. Interactions between genes were indicated by STRING software and REACTOME FIViz application to the Cytoscape 3.6.0 software. Most of the genes belonged to more than one ontology group. Although studied genes are mostly responsible for angiogenesis and circulatory system development, they can also be found to be expressed in processes connected with fertilization and early embryo development. The latter function is focused on more, considering the fact that these genes were expressed in epithelial cells of the fallopian tube which is largely responsible for reproductive processes.

Abstract The process of reproduction requires several factors, leading to successful fertilization of an oocyte by a single spermatozoon. One of them is the complete maturity of an oocyte, which is acquired during long stages of folliculogenesis and oogenesis. Additionally, the oviduct, composed of oviductal epithelial cells (OECs), has a prominent influence on this event through sperm modification and supporting oocyte’s movement towards uterus. OECs were isolated from porcine oviducts. Cells were kept in primary in vitro culture for 30 days. After 24h and on days 7, 15 and 30 cells were harvested, and RNA was isolated. Transcript changes were analyzed using microarrays. Fatty acids biosynthetic process and fatty acids transport ontology groups were selected for analysis and described. Results of this study indicated that majority of genes in both ontology groups were up-regulated on day 7, 15 and 30 of primary in vitro culture. We analyzed genes involved in fatty acids biosynthetic process, including: GGT1, PTGES, INSIG1, SCD, ACSL3, FADS2, FADS1, ACSS2, ALOX5AP, ACADL, SYK, ACACA, HSD17B8, FADS3, OXSM, and transport, including: ABCC2, ACSL4, FABP3, PLA2G3, PPARA, SYK, PPARD, ACACA and P2RX7. Elevated levels of fatty acids in bovine and human oviducts are known to reduce proliferation capacity of OECs and promote inflammatory responses in their microenvironment. Most of measured genes could not be connected to reproductive events. However, the alterations in cellular proliferation, differentiation and genes expression during in vitro long-term culture were significant. Thus, we can treat them as putative markers of changes in OECs physiology.

AbstractThe oviduct is a part of female reproductive tract that is essential for successful fertilization and early embryo development. It is lined with epithelium consisting of two types of cells: ciliated and secretory. The primary function of ciliated oviductal epithelial cells (OECs) is to support the transport of gametes and embryos through the ovary, whereas secretory OECs produce components of the oviductal fluid. Undoubtedly, the oviductal epithelium plays a major part in the early aspects of pregnancy development, from providing an optimal environment for gametes and embryos to supporting fertilization. Therefore, our aim was to gain a better insight into the genetic changes underlying function of these cells. We have harvested OECs from crossbred gilts (n=45), at the age of about nine months and which displayed two regular estrous cycles, and established long-term primary culture of porcine OECs. Microarray analysis was utilized to determine differentially expressed genes during day 1, 7, 15 and 30 of cultivation, with our results revealing54 differentially expressed genes belonging to three ontology groups: „maintenance of location”, „maintenance of protein location” and „maintenance of protein location in cell”. Since the biochemistry and morphology of epithelial cells may change during long term cultivation, we conclude that our results are a reflection of these changes and help to shed a light on porcine OECs properties in in vitro environment.Running title: Maintenance of cellular protein location in porcine epithelial oviductal cells

Next-generation sequencing (RNAseq) analysis of gene expression changes during the long-term in vitro culture and osteogenic differentiation of ASCs remains to be important, as the analysis provides important clues toward employing stem cells as a therapeutic intervention. In this study, the cells were isolated from adipose tissue obtained during routine surgical procedures and subjected to 14-day in vitro culture and differentiation. The mRNA transcript levels were evaluated using the Illumina platform, resulting in the detection of 19,856 gene transcripts. The most differentially expressed genes (fold change >|2|, adjusted p value < 0.05), between day 1, day 14 and differentiated cell cultures were extracted and subjected to bioinformatical analysis based on the R programming language. The results of this study provide molecular insight into the processes that occur during long-term in vitro culture and osteogenic differentiation of ASCs, allowing the re-evaluation of the roles of some genes in MSC progression towards a range of lineages. The results improve the knowledge of the molecular mechanisms associated with long-term in vitro culture and differentiation of ASCs, as well as providing a point of reference for potential in vivo and clinical studies regarding these cells’ application in regenerative medicine.
