  • a CD designations indicate patients with Chron's disease, UC designations indicate patients with ulcerative colitis, and H designations indicate healthy controls.

  • b A DNA clone library was obtained from each of the tissues according to the procedure detailed in Materials and Methods. Bold type indicates inflamed tissue. Italic type indicates tissue with patchy inflammation, where biopsy samples were taken from both healthy and inflamed sections.
