Adult intestinal stem cells are grown into closed 3D structures with protruding buds and a luminal compartment. These 3D structures are produced from the stem cells present in the base of crypts isolated from rectal mucosa samples that can be collected by suction or forceps biopsy. The crypts are

Zebrafish-based platforms have recently emerged as a useful tool for toxicity testing as they combine the advantages of in vitro and in vivo methodologies. Nevertheless, the capacity to metabolically convert xenobiotics by zebrafish eleuthero embryos is supposedly low. To circumvent this concern, a

The spatiotemporal distribution of fluorescent compounds was examined during 48 h after immersion (10 µM) or microinjection (2 mg/kg) in the pericardial cavity (PC), intraperitoneally (IP) and yolk sac (IY) of 3 dpf zebrafsh eleuthero-embryos. By modelling the fluorescence of whole-body contours

Immersion treatment: zebrafish embryos at the two-cell stage were immersed in Danieau’s medium containing the compound. A compound concentration of 10 µM and DMSO concentration of 0.1% (v/v) in a volume of 5 mL was used per well (6-well-plates). At 72 h, the zebrafish medium containing the compound

The method is an approach to systematically study the impact of the nutrient microenvironment on the metabolism of effector CD8+ T cells, based on performing stable 13C isotope labeling measurements on in vitro-differentiated murine effector CD8+ T cells. Naive CD8+ T cells are isolated from mouse

Metabolomics and 13C tracer analysis are state-of-the-art techniques that allow determining the concentration of metabolites and the activity of metabolic pathways, respectively. Three dimensional (3D) cultures of cancer cells constitute an enriched in vitro environment that can be used to assay

Generally, our research group aims to study the influence of food parameters (food design, food processing, food composition) on the digestive kinetics of diverse nutrients throughout the upper gastrointestinal tract. For this, we use in vitro digestion protocols. The current method is a semi

Human Intestinal Organoids (HIOs) are in vitro 3D cell cultures arranged in a crypt-villus structure that incorporate many physiological features of the intestinal epithelium, including the presence of different cell populations (enterocytes, goblet cells, enteroendocrine and Paneth cells). HIOs can

Intestinal organoids are cultured from intestinal biopsies obtained during routine endoscopy. The stem cell containing crypts are isolated and cultured in a 3D ECM (Matrigel) in the presence of the desired growth factors. The present stem cells will expand and give rise to all epithelial cells of
