CloneticsTM InEpC's are truly primary cells representing both villi (enterocytes, goblet, and enteroendocrine cells) and crypts structures.  In combination with human intestinal myofibroblasts (InMyoFib), InEpC are able to form very tight cell monolayer, representing a unique in vitro system to model human intestinal homeostasis. Human intestinal epithelial cells (InEpC) are of pivotal importance in the digestion and absorption of nutrients and the protection of the organism from bacteria and toxins found in the intestine. The intestinal epithelium is a highly organized cellular system maintained in a dynamic steady state by cells in proliferation and differentiation, which die and exfoliate into the lumen. Intestinal cells are often difficult to isolate due to contamination issues and usually have to be cultured and used for assays immediately after isolation from tissue.
