Experimental details: Immunoprecipitation was performed on HEK293T cells overexpressing LGR5. Antigen-antibody complexes were formed by incubating the sample with 2 µg of LGR5 monoclonal antibody (Product # MA5-25644) antibody and 0.1 mg of goat anti-mouse conjugated magnetic beads overnight. The sample was washed extensively and probed with rabbit anti-DDK polyclonal antibody.

Experimental details: FIGURE 2 Epithelium cell proliferation and Lgr5 + stem cell maintenance were preserved during the early 3 days of DSS colitis. (A) Immunofluorescence staining for Ki67 in colon tissue from mice treated with DSS at 0, 3, 5, and 7 days (red: Ki67, blue: DAPI). (B) Quantification of Ki67-positive cells per crypt ( n = 5). (C) Immunofluorescence staining for Lgr5 in colon tissue from mice treated with DSS at 0, 3, 5, and 7 days (green: Lgr5, blue: DAPI). (D) Quantification of Lgr5-positive cells per crypt ( n = 5). Data represent mean +- SD with three independent experiments. One-way ANOVA and Bonferroni test for multiple testing was applied in all cases. ** p < 0.01, *** p < 0.001. Scale bar = 25 mum.

Experimental details: Fig. 3. LGR5 is highly expressed in nasal organoids. The stem cell marker Lgr5 mRNA expression levels in organoids and monolayer cultures, GAPDH was used as a housekeeping gene and data were normalised to GAPDH. The values are shown as means+-s.e.m., n =5, ** P =0.001 (A). Representative immunofluorescence of 10-12-day-old organoid showing expression of MUC2 (mucus secreting cell, red) and Lgr5 (stem cell marker, green). DAPI stains nuclei blue (B), Scale bar: 20 um and 20x objective.
