Evaluation of enhanced green fluorescent protein (EGFP) fluorescence in the colon of IL-10wt/wt/NF-κBEGFP and IL-10−/−/NF-κBEGFP mice fed control or 1% curcumin-supplemented diet. Germ-free mice were colonized with SPF flora and euthanized 28 days postcolonization. A: colon and cecum were resected and EGFP fluorescence was imaged as described in materials and methods. B: confocal imaging of colonic mucosa immediately after dissection was performed as described in materials and methods, with predominantly interstitial cells being EGFP positive and thus likely representing LPL mononuclear cells.
