Depletion of CD90+ ILCs was performed as previously described, with some modifications (36 (link)). Two hundred and fifty micrograms of a mAb to CD90.2 or an isotype control rat IgG2b (BioXCell, West Lebanon, NH) was given by means of intra-peritoneal injection a total of three times at 3-day intervals. Intestinal ECs and LP cells were collected 2 days after the final injection.
