Enteroids are emerging as a novel model in the study of human disease. The protocol describes how to simulate an enteroid model of human necrotizing enterocolitis using lipopolysaccharide (LPS) treatment of enteroids generated from neonatal tissue. Collected enteroids demonstrate inflammatory changes akin to those seen in human necrotizing enterocolitis.

The present protocol outlines a method that utilizes lucifer yellow in an apical-out enteroid model to determine intestinal permeability. This method can be used to determine paracellular permeability in enteroids that model inflammatory bowel diseases such as necrotizing enterocolitis.
