Here we describe a simple method for the isolation of spatially distinct murine colonic epithelial surface cells from the underlying crypt-base cells.

Systematic scoring of intestinal inflammation using a free computer-assisted system is a powerful tool to quantitatively compare histopathological changes in colitis models characterized by the presence of ulcers and inflammatory changes. Histological colitis score evaluation strengthens clinical observations and facilitates data interpretation.

Generation of Murine Primary Colon Epithelial Monolayers from Intestinal Crypts

Chithra K Muraleedharan¹, Jay Mierzwiak¹, Darius Feier¹, Asma Nusrat¹, Miguel Quiros¹

¹Department of Pathology, School of Medicine, University of Michigan

In this protocol, we describe how to generate murine primary epithelial colon monolayers directly from intestinal crypts. We provide experimental approaches to generate confluent monolayers on permeable filters, confluent monolayers for scratch wound healing and biochemical studies, and sparse and confluent monolayers for immunofluorescence analysis.
