Abstract
Organoids are complex three-dimensional structures, which contain different cell types and help to overcome many limitations of conventional 2D cell culture techniques. Here, we present a protocol for the cultivation of murine matched-pairs of small intestinal and colonic epithelial organoids, and colonic tumor organoids derived from the chemical colorectal cancer (CRC) AOM/DSS mouse model. Therefore, intestinal crypts or tumor tissue containing stem cells are isolated from the same donor mouse and cultivated in Matrigel®. The culture medium is supplemented with different growth factors to model the intestinal stem cell niche, allowing their self-renewal and differentiation. Matched-pair organoids enable the analysis of pharmacological effects and the tumor selectivity of drugs.

Schematic overview of colonic matched pair organoid preparation, generated from the chemical AOM/DSS colorectal cancer mouse model. Please note that normal colon-derived organoids (green) differ in their morphology from tumor-derived organoids (red). Normal colonic-derived organoids display a thicker and crypt-like epithelial layer, whereas tumor-derived organoids are round with a thin epithelial layer.
Background
Organoids are three dimensional structures, which are derived from pluripotent stem cells or organ restricted stem cells. They have the ability for self-organization and differentiation, mirroring key functional and structural properties of the respective organ (Clevers, 2016). Over the past decades, organoid culture became an important model in the fields of personalized and targeted therapies as well as for the prediction of drug responses (Lancaster and Knoblich, 2014; Clevers, 2016). Hence, organoids have become indispensable for many fields of biomedical and translational research (Wallach and Bayrer, 2017; Fair et al., 2018; Almeqdadi et al., 2019).
In the context of colorectal cancer (CRC), we provide a protocol to generate murine matched-pair organoids, to evaluate the cytotoxicity and tumor selectivity of certain cancer drugs.
Intestinal organoids were first established by Sato et al. (2009) from small intestinal stem cells for long-term culture in a collagen matrix. The technique was then further developed by the same research group, enabling organoid cultures from normal epithelium and tumor tissue from the colon (Sato et al., 2011).
Based on previously published protocols for intestinal organoids (O’Rourke et al., 2016; https://www.stemcell.com/technical-resources/intestinal-epithelial-organoid-culture-with-intesticult-organoid-growth-medium-mouse-lp.htmL), we summarize our modified step-by-step protocol for the generation of murine matched pair organoids. In contrast to previous protocols, we used three different cell lines to generate Wnt3a, Noggin, and Rspondin-1 conditioned medium. These components are essential for proper self-renewal and proliferation of the stem cell pool. Furthermore, we provide detailed protocols for further analysis of drug-treated organoids, such as RNA and protein isolation, morphological quantification, membrane permeability staining using propidium iodide/ Hoechst 33342, and an ATP-based cell viability assay (CellTiter-Glo® 3D).
