Cross Section of An Injury in the Large Intestine (image) Technical University of Munich (TUM) Share Print E-Mail Caption This is a cross section of an injury in the large intestine with the intestinal epithelium shown in red. The healing process is characterized by rapid cell division in the wound region (green areas). Where there is a high concentration of the CHOP protein, the epithelium is slower to heal (region with red outline). Credit N.
