  • Organoid derivation and orthotopic xenotransplantation for studying human intestinal stem cell dynamics

    Sugimoto S., Fujii M., Sato T., Methods in Molecular Biology, 2020

    　View Summary

    Intestinal stem cells continuously self-renew throughout life to maintain gut homeostasis. With the advent of the organoid culture system, we are now able to indefinitely expand healthy and diseased tissue-derived human intestinal stem cells in vitro and use them for various applications. Nonetheless, investigating the behavior of human intestinal stem cells in vivo still remains challenging. We recently developed an orthotopic xenotransplantation system that realizes in vivo reconstruction of human intestinal epithelial tissue with preserved stem cell hierarchy by engrafting human normal colon organoids onto the mouse colon surface. We also introduced new growth factors, namely, insulin-like growth factor-1 (IGF-1) and fibroblast growth factor-2 (FGF-2), into the culture condition for human intestinal organoids that significantly increase scalability and transfectability of the organoids. By integrating these recent advances, we organized a tissue-oriented platform encompassing derivation of patient-derived intestinal organoids and their orthotopic xenotransplantation. The research platform based on orthotopic xenotransplantation of human intestinal organoids provides a powerful tool for studying human intestinal stem cell biology in native tissue-relevant contexts as well as for establishing novel disease modeling systems.

  • Establishment of 3D intestinal organoid cultures from intestinal stem cells

    Sugimoto S., Sato T., Methods in Molecular Biology, 2017

    　View Summary

    The intestinal epithelium is the most rapidly renewed tissue in adult mammals, and its renewal is strictly controlled by intestinal stem cells. Extensive studies using genetic models of intestinal epithelium have revealed the mechanisms underlying the self-renewal of intestinal stem cells. Exploiting this knowledge, we developed a novel 3D culture system that enables the outgrowth of intestinal Lgr5+ stem cells derived from mouse and human tissues into ever-expanding crypt–villus mini-guts, known as intestinal epithelial organoids. These organoids are maintained by the self-renewal of stem cells and give rise to all differentiated cell types of the intestinal epithelium. Once established, organoids can be cryopreserved and thawed when needed. This culture system has been widely used for studying stem cell behavior and gene function and for disease modeling.

  • Evaluation of drug-induced lymphocyte stimulation test in mesalazine-associated allergic drug reaction

    　View Summary

    Background: 5-Aminosalicylic acid (5-ASA) is a fundamental drug for UC management; however, adverse reactions can lead to poor clinical outcomes and increased health care costs. No objective tests currently exist to predict adverse reactions. This study thus investigated 5-ASA across 4 formulations and addressed a key issue in the treatment of mild to moderate ulcerative colitis (UC). Objective: We aimed to examine the utility of the drug-induced lymphocyte stimulation test (DLST) in predicting successful rotation from mesalazine to sulfasalazine (SASP) in patients with UC. Methods: We retrospectively analyzed the largest cohort to date of patients with UC who were suspected of 5-ASA–associated adverse reactions and underwent DLST. We evaluated the DLST positivity rate for the suspected formulation, cross-reactivity to nonsuspected formulations, and clinical outcomes after rotation from mesalazine to SASP. Results: Mesalazine formulations exhibited a DLST positivity rate of 22.0% (18/82), with 45.1% (37/82) of patients testing positive for at least one 5-ASA formulation. Cross-reactivity between mesalazine and SASP was lower at 12.2% (10/82), likely because of structural differences. Adverse reactions typically developed within 2 weeks of initiating 5-ASA and commonly included fever, diarrhea, and bloody stool. Among patients with mesalazine-associated adverse reactions with DLST-negative test result for SASP, 8 of 12 tolerated the rotation. Rotation failure was mainly associated with a positive or borderline DLST result for mesalazine. Conclusions: DLST serves as a useful diagnostic tool for guiding treatment in patients with UC and suspected 5-ASA–associated hypersensitivity reactions. Prospective multicenter studies are needed to validate its clinical utility.

    　View Summary

    Short bowel syndrome (SBS) is a life-threatening condition in which outcomes often critically depend on ileal function, the only intestinal segment specialized for bile acid uptake and efficient fat absorption. However, whether restoring ileal epithelium-specific nutrient absorption can ameliorate SBS has remained unknown. Here, we demonstrate a niche-preserving transplantation strategy enabling highly efficient engraftment of intestinal organoids into the rat small intestine. Clearing luminal mucus with N-acetylcysteine facilitates ethylenediaminetetraacetic acid (EDTA)-based epithelial detachment, enabling removal of Lgr5<sup>+</sup> stem cells while preserving the stromal niche. This preconditioning increased the engrafted area and enabled the generation of an ilealized jejunum that improved body-weight trajectories and survival in rat SBS. Furthermore, the engrafted epithelia endowed the jejunum with bile acid absorption capacity. These findings provide in vivo evidence for stem cell niche theory, showing that the niche is essential to accommodate donor stem cells, and establish ilealized jejunum as a path toward autologous, region-targeted therapy for SBS.
