between gut microbes, intestinal epithelial cells and the immune system, but so far it has been impossible to determine how each of these factors contribute to the development of intestinal bowel disease,» said Hyun Jung Kim, Ph.D., former Wyss Technology Development Fellow and first author on the study, speaking about the limitations of conventional in vitro and animal models of bacterial overgrowth and inflammation of the intestines.
