Abstract
The molecular complexity of host-pathogen interactions remains poorly understood in many infectious diseases, particularly in humans due to the limited availability of reliable and specific experimental models. To bridge the gap between classical two-dimensional culture systems, which often involve transformed cell lines that may not have all the physiologic properties of primary cells, and in vivo animal studies, researchers have developed the organoid model system. Organoids are complex three-dimensional structures that are generated in vitro from primary cells and can recapitulate key in vivo properties of an organ such as structural organization, multicellularity, and function. In this review, we discuss how organoids have been deployed in exploring Salmonella infection in mice and humans. In addition, we summarize the recent advancements that hold promise to elevate our understanding of the interactions and crosstalk between multiple cell types and the microbiota with Salmonella. These models have the potential for improving clinical outcomes and future prophylactic and therapeutic intervention strategies.

Abstract
Significant progress has been made in the development of CFTR modulator therapy; however, current CFTR modulator therapies are only available for a minority of the CF-patient population. Additionally, heterogeneity in in vivo modulator response has been reported among individuals carrying homozygous F508del-CFTR, adding to the desire for an optimal prediction of response-to-therapy on an individual level. In the last decade, a lot of progress has been made in the development of primary cell cultures into 3D patient-derived disease models. The advantage of these models is that the endogenous CFTR function is affected by the patient's mutation as well as other genetic or environmental factors. In this review we focus on intestinal organoids as in vitro model for CF, enabling for CF disease classification, drug development and treatment optimization in a personalized manner, taking into account rare CFTR mutations and clinical heterogeneity among individuals with CF.

Osteogenic Potential of Human Umbilical Cord Mesenchymal Stem Cells on Coralline Hydroxyapatite/Calcium Carbonate Microparticles. Stem Cells Int 2018; 2018:4258613.

Abstract
Coralline hydroxyapatite/calcium carbonate (CHACC) is a biodegradable and osteoconductive bone graft material with promising clinical performance. CHACC has been shown to support proliferation and osteogenic differentiation of human bone marrow mesenchymal stem cells (MSCs) in vitro and demonstrated to work as a functional scaffold for bone formation in vivo. Umbilical cord matrix is a more accessible and abundant tissue source of MSCs, but its osteogenic capacity in comparison to human bone marrow when cultured on CHACC has not yet been demonstrated. In this study, we assessed the osteogenic differentiation capacity of human MSCs, isolated from bone marrow and umbilical cord matrix and characterised by flow cytometry, when cultured on 200–300 μm CHACC granules. The 3D cultures were characterised by brightfield and scanning electron microscopy (SEM). Osteogenic potential was assessed by immunocytochemistry and qPCR for key markers of bone differentiation (alkaline phosphatase, runx2, type I collagen, and osteocalcin). By day 1, the MSCs had enveloped the surface of the CHACC granules to form organoids, and by day 7, cells had proliferated to bridge nearby organoids. Extracellular matrix deposition and osteogenic differentiation were demonstrated by MSCs from both tissue sources at day 21. However, MSCs from bone marrow demonstrated superior osteogenic differentiation capability compared to those from umbilical cord matrix. In conclusion, it is possible to culture and induce osteogenic differentiation of umbilical cord matrix MSCs on CHACC. Further research is required to optimise the osteogenicity of umbilical cord matrix MSCs to release their full potential as a readily available, accessible, and abundant tissue source for bone tissue engineering.

Abstract
Intestinal resection and malformations in adult and pediatric patients result in devastating consequences. Unfortunately, allogeneic transplantation of intestinal tissue into patients has not been met with the same measure of success as the transplantation of other organs. Attempts to engineer intestinal tissue in vitro include disaggregation of adult rat intestine into subunits called organoids, harvesting native adult stem cells from mouse intestine and spontaneous generation of intestinal tissue from embryoid bodies. Recently, by utilizing principles gained from the study of developmental biology, human pluripotent stem cells have been demonstrated to be capable of directed differentiation into intestinal tissue in vitro. Pluripotent stem cells offer a unique and promising means to generate intestinal tissue for the purposes of modeling intestinal disease, understanding embryonic development and providing a source of material for therapeutic transplantation.

Abstract
The characterization of metabolic activity of intestinal cells in culture may be of particular interest for the study of the effects of food additives and contaminants which, ingested through the diet, are absorbed primarily by the gut mucosa. IEC-17 cell line is derived from the intestine of newborn rat and has been shown to be competent for the metabolism of xenobiotics (Quaroni and Isselbacher, 1981), and to keep some degree of differentiation also in in vitro conditions. Our studies indicate that the xenobiotic metabolic activity of this cell line, as shown by measurement of 7-ethoxycoumarin (7-EC), can be induced by beta-naphthoflavone (NF) and not by phenobarbital (PB) and only at late subculturing stages, suggesting these cells undergo some kind of maturation in vitro. Induction of xenobiotic metabolism by beta-naphthoflavone seems also to elicit the toxicity of 9,10-dimethyl-1,2-benzathracene (DBA) but not that one of cyclophosphamide (CPA).

Abstract
An intestinal epithelial cell line from neonatal rat duodenum (IEC-17) was used as a model for investigating metal toxicity. In this paper, we have further characterised toxic effects on IEC-17 cells following exposure to two physiological metals, zinc (Zn2+) and copper (Cu2+) and one non-physiological metal, cadmium (Cd2+). Time-effect experiments showed that the duration of the exposure affected the extent of cell damage only when Cu2+ and Cd2+ were used. During the first 48 hours of Zn2+ exposure, the cells were seriously affected, but subsequently were able to recover. On the other hand, a colony forming ability test and morphological observations showed a special sensitivity of this cell line to Cu2+. A possible explanation is suggested in relation to extracellular matrix formation.

Abstract
An intestinal epithelial cell line (IEC-17), undergoing a process of progressive morphological differentiation, was analysed for expression and synthesis of the extracellular matrix glycoproteins, fibronectin (FN) and laminin (LM). FN and LM cell surface expression was detected by immunoelectron microscopy, while intracytoplasmic accumulation was shown by immunofluorescence. 35S-methionine metabolic labelling was also performed to demonstrate FN and LM synthesis by IEC-17. We have compared two different maturation stages of the cell culture and have found that either early epithelial monolayer cells or later multistratified organoid structure cells expressed and produced large amounts of both proteins. These results indicate that FN and LM are constantly present during the process of IEC-17 organoid maturation: we can hypothesize that the two proteins act as mediators of cell to cell and cell to substrate adhesion interactions and, probably, have an active regulatory role in the process of intestinal epithelial cell differentiation.

Abstract
The culture of animal cells and tissues is a widely used technique in the field of cellular and molecular biology; one of the most interesting aspect being linked to the study of the mechanisms of cell differentiation. In the specific case of intestinal epithelial cells, various tissue culture technologies have proved to be important tools for the study of precise facets related to intestinal function, pathology and differentiation. Concerning this latter aspect, organ culture experiments have brought about interesting data on the hormonal or nutritional control of intestinal maturation. Nevertheless, the study of the precise mechanisms underlying epithelial proliferation and/or differentiation at the cellular level needs more adequate cell culture model systems. One of them has been described for two cell lines derived from human colonic adenocarcinomas, in which the cells can be induced to achieve enterocytic-like differentiation. Up to date, none of the continuous cell lines starting from normal undifferentiated cells have allowed generation of morphological or functional enterocytic polarity. In contrast, primary cell cultures which allow maintenance of a more physiological environment for the epithelial cells like contacts with their in vivo counterparts, mesenchymal cells or extracellular matrix molecules, have proved to be promising approaches.
