IL11 and digestive system cancer: Of note, EGFP+ cells only appeared in the colon tumors of ApcMin/+;Il11-Egfp reporter mice, but not ApcMin/+ mice (Supplementary Fig. 3a), indicating that EGFP signals in ApcMin/+;Il11-Egfp reporter mice did not likely reflect the autofluorescence, but represented specific signals of IL-11.
