Supplementary Figure 1: iILC2 cells are induced in several sites of mice by IL-25 treatment.

Wild-type B6 mice were treated i.p. with PBS or IL-25 daily for 3 days and leukocytes form various tissues were isolated and analyzed by flow cytometry for ST2, KLRG1 and lineage markers expression. Cells were gated from Lin–. Data are representative of two independent experiments (n=3 mice for each group in each experiment).
