Epithelial organoid culture system. Crypts cultured in Matrigel with EGF, Noggin, and R-spondin-1 form intestinal organoid structures, and organoid growth was used as a model of intestinal regeneration. A) Sorted RORyt-GFP+ ILC3s cultured with an IL-23 cytokine cocktail increase SI organoid size, which is blocked by anti- IL-22 neutralizing antibody. B) rhlL-22 increases the size of human (Hu) duodenal organoids cultured in standard expansion medium (EM), C) ISC elimination by culturing Lgr5-DTR organoids with diptheria toxin (DT) eliminates IL-22-dependent growth. D) Stat3 deficiency induced by culturing Stat3m crypts with adenoviral-Cre prevents organoid growth and response to IL-22, *p<.05, ***p<.001.
