Intestinal organoid cultures are a powerful tool to study epithelial cells , as they are able to proliferate and differentiate into all cell lineages observed . Co-culturing organoids with distinct genetic backgrounds provides an excellent approach to study contact dependent and independent interactions between healthy and mutant epithelial intestinal cells. Here, we provide 2D and 3D approaches to mouse organoid co-cultures using fluorescently labeled organoids and demonstrate the analysis of these co-cultures using flow cytometry and microscopy-based approaches. For complete details on the use and execution of this profile, please refer to van Neerven et al., 2021.

Organoid technology, as an innovative approach in biomedicine, exhibits promising prospects in disease modeling, pharmaceutical screening, regenerative medicine, and oncology research. However, the use of tumor-derived Matrigel as the primary method for culturing organoids has significantly impeded the clinical translation of organoid technology due to concerns about potential risks, batch-to-batch instability, and high costs. To address these challenges, this study innovatively introduced a photo-crosslinkable hydrogel made from a porcine small intestinal submucosa decellularized matrix (SIS), fish collagen (FC), and methacrylate gelatin (GelMA).

Some strains of can cause spondylitis and bacterial osteomyelitis. Translocation and bacteremia are pivotal to the pathogenesis and clinical disease. Virulence typing to distinguish extra-intestinal disease of lesion from cloacal strains remains difficult.

Limiting animal experiments is essential for ethical issues and also because scientific evidence highlights the discrepancies between human and animal metabolism. This review aims to provide a critical discussion of the strengths and limitations of the most appropriate intestine model to answer complex research questions in pharmaceutical and nutraceutical fields. This review describes the components contributing to the definition of the gut barrier structure, from the outer mucus layer to the inner part of lamina propria, including endothelial and neuronal networks.

The intestines are an important organ with a variety of functions. For drug discovery research, experimental animals and Caco-2 cells derived from a human colon carcinoma may be used to evaluate the absorption and safety of orally administered drugs. These systems have issues, such as species differences with humans in experimental animals, variations in gene expression patterns, very low drug-metabolizing activities in Caco-2 cells, and the recent trend toward reduced animal testing.

Here, we aimed to provide a better understanding to the function of PROX1+ cells in CRC, investigating their progeny and their role in therapy resistance. PROX1+ cells in intestinal adenomas of ApcMin/+ mice expressed intestinal epithelial and CRC stem cell markers, and cells with high PROX1 expression could both self-renew tumor stem/progenitor cells and contribute to differentiated tumor cells.
