| Treatment protocol |
Mice were sacraficed and organs were harvested. For polyp-ridden APC mice, small intestine polyps were microdisected from health surrounding tissue; both parts were used as a source of mononuclear cells. Mononuclear cells from small intestine tissue were isolated by collengenase IV digestion and precoll gradient centrifugation. Cells from spleen and mesenteric lymph nodes were isolated by gentlely teasing between frosted glass slides. Spleen cells were subjected to red blood cell lysis. Negative selection with T-cell negative selection kit (Dynal beads; Invitrogen) was used to pre-purify cells. Cells were Pc blocked and then stained with CD4 antibody. PI was used to exclude dead cells during FACS sorting. Cells were then double sorted on a MoFlo sorter. A doublet exclusion gate was included. Cells were then gated on PI negative, CD4+ cells. Two populations were then collected directly into Trizol: CD4+Foxpe-GFP- and CD4+Foxp3-GFP+. Cell isolation and sorting were performed according to immgen.org SOP.

| Data processing |
The datasets were pre-filtered to keep only those probesets for which a gene symbol could be found in the affymetrix annotation. CEL files were normalized using Affymetrix Power tools on the predefined probeset ID list mentioned above, and using the standard RMA workflow (background adjustment, quantiile normalization, median polish probeset summarization).
