    Abstract

    IL-38 Regulates Intestinal Stem Cell Homeostasis by Inducing WNT Signaling and Beneficial IL-1β Secretion

    Cultures of intestinal organoids revealed that IL-38 functioned as a growth factor by increasing organoid size via inducing WNT3a. In contrast, organoids from IL-38-deficient mice developed more slowly.
