Representative quantitative histology images. Images from colonic sections of 3% or 1% DSS-treated, wild-type mice collected on days 0, 7, and 14. (A) Sections were stained for Ki-67 (red) and DAPI (blue) and imaged with a 63x oil objective. (B) Sections were stained with PAS for goblet cells and imaged with a 20x dry objective. (C) Sections were TUNEL-stained (green) for apoptotic cells, counterstained for DAPI (blue), and imaged with a 63x oil objective. All scale bars = 50 μm.
