What Our Scientist Says
Organoids have truly expanded the limits of what's possible for in vitro studies of the intestinal epithelium. By providing optimized culture media and robust, approachable protocols, we are making these technologies more accessible to researchers.
Ryan ConderAssociate Director, Gastrointestinal Biology
Model key characteristics of the adult intestinal epithelium using intestinal organoids established and maintained with this complete medium formulation and optimized protocol. Using the easy-to-follow and robust protocol, you can derive organoids from human intestinal crypts in one week; organoid growth across donor samples, including those that are otherwise difficult to grow, is enabled by an enriched stem cell population.
Organoids grown in IntestiCult™ Organoid Growth Medium (Human) incorporate a functional lumen enclosed by a polarized intestinal epithelial cell layer and, for versatile modeling applications, can be further differentiated in 3D or in 2D as submerged monolayers or air-liquid interface (ALI) cultures using IntestiCult™ Organoid Differentiation Medium (Human; Catalog #100-0214).
Applications of intestinal organoid cultures include studying the development and function of intestinal epithelium, modeling intestinal diseases, and screening molecules for both efficacy and toxicity in an intestinal model. Intestinal organoid cultures can also be used for investigation of adult stem cell properties and for regenerative therapy approaches.

Organoid cultures are imaged at the end of passage 4. All four extracellular matrices supported robust growth of human intestinal organoids. Scale bars = 250 μm.

(C) Immunofluorescence staining of the colon organoid tubule confirms an adult tissue phenotype with the presence of goblet cells (Muc2), enterocytes (Occludin), and stem cells (Sox9). The 3D-lumenized structure provides apical (Ezrin) and basolateral (Integrin-β4) access to the polarized epithelium. Additionally, the organoid tubules show polarized and modulatable activity of expression of P-glycoprotein (Pgp).
(D) The OrganoReady® Colon Organoid platform supports toxicity testing, as demonstrated by dose-dependent measurements of TEER, LDH, and ATP following exposure to Afatinib (n = 4, N = 2). After 72 hrs of exposure, a dose dependent decrease in TEER, cytotoxicity, and cell viability was observed. For more information, please visit mimetas.com/en/organoready-organoid/.

In vivo development of immune tissue in human intestinal organoids transplanted into humanized mice. C. Bouffi et al. Nature biotechnology 2023 6
Abstract
Human intestinal organoids (HIOs) derived from pluripotent stem cells provide a valuable model for investigating human intestinal organogenesis and physiology, but they lack the immune components required to fully recapitulate the complexity of human intestinal biology and diseases. To address this issue and to begin to decipher human intestinal-immune crosstalk during development, we generated HIOs containing immune cells by transplanting HIOs under the kidney capsule of mice with a humanized immune system. We found that human immune cells temporally migrate to the mucosa and form cellular aggregates that resemble human intestinal lymphoid follicles. Moreover, after microbial exposure, epithelial microfold cells are increased in number, leading to immune cell activation determined by the secretion of IgA antibodies in the HIO lumen. This in vivo HIO system with human immune cells provides a framework for future studies on infection- or allergen-driven intestinal diseases.
Catechol-O-Methyltransferase Loss Drives Cell-Specific Nociceptive Signaling via the Enteric Catechol-O-Methyltransferase/microRNA-155/Tumor Necrosis Factor ? Axis Q. Zhou et al. Gastroenterology 2023 4
Abstract
BACKGROUND & AIMS The etiology of abdominal pain in postinfectious, diarrhea-predominant irritable bowel syndrome (PI-IBS-D) is unknown, and few treatment options exist. Catechol-O-methyltransferase (COMT), an enzyme that inactivates and degrades biologically active catecholamines, plays an important role in numerous physiologic processes, including modulation of pain perception. Our objective was to determine the mechanism(s) of how decreased colonic COMT in PI-IBS-D patients contributes to the chronic abdominal pain phenotype after enteric infections. METHODS Colon neurons, epithelial cells, and macrophages were procured with laser capture microdissection from PI-IBS-D patients to evaluate cell-specific colonic COMT, microRNA-155 (miR-155), and tumor necrosis factor (TNF) ? expression levels compared to recovered patients (infection cleared: did not develop PI-IBS-D) and control individuals. COMT-/-, colon-specific COMT-/-, and miR-155-/- mice and human colonoids were used to model phenotypic expression of COMT in PI-IBS-D patients and to investigate signaling pathways linking abdominal pain. Citrobacter rodentium and trinitrobenzene sulfonic acid animal models were used to model postinflammatory changes seen in PI-IBS-D patients. RESULTS Colonic COMT levels were significantly decreased and correlated with increased visual analog scale abdominal pain ratings in PI-IBS-D patients compared to recovered patients and control individuals. Colonic miR-155 and TNF-? were increased in PI-IBS-D patients with diminished colonic COMT. COMT-/- mice had significantly increased expression of miR-155 and TNF-? in both colon tissues and dorsal root ganglia. Introduction of cV1q antibody (anti-TNF-?) into mice reversed visceral hypersensitivity after C rodentium and trinitrobenzene sulfonic acid. CONCLUSIONS Decreased colonic COMT in PI-IBS-D patients drives abdominal pain phenotypes via the COMT/miR-155/TNF-? axis. These important findings will allow new treatment paradigms and more targeted and personalized medicine approaches for gastrointestinal disorders after enteric infections.
3D bioprinted colorectal cancer models based on hyaluronic acid and signalling glycans. F. Cadamuro et al. Carbohydrate polymers 2023 2
Abstract
In cancer microenvironment, aberrant glycosylation events of ECM proteins and cell surface receptors occur. We developed a protocol to generate 3D bioprinted models of colorectal cancer (CRC) crosslinking hyaluronic acid and gelatin functionalized with three signalling glycans characterized in CRC, 3'-Sialylgalactose, 6'-Sialylgalactose and 2'-Fucosylgalactose. The crosslinking, performed exploiting azide functionalized gelatin and hyaluronic acid and 4arm-PEG-dibenzocyclooctyne, resulted in biocompatible hydrogels that were 3D bioprinted with commercial CRC cells HT-29 and patient derived CRC tumoroids. The glycosylated hydrogels showed good 3D printability, biocompatibility and stability over the time. SEM and synchrotron radiation SAXS/WAXS analysis revealed the influence of glycosylation in the construct morphology, whereas MALDI-MS imaging showed that protein profiles of tumoroid cells vary with glycosylation, indicating that sialylation and fucosylation of ECM proteins induce diverse alterations to the proteome of the tumoroid and surrounding cells.
