Urinary bladder-Ulcerative chronic interstitial cystitis patients vs. Urinary bladder-Normal controls

Microarray gene expression analysis of urinary bladder tissues from interstitial cystitis (IC) patients. From each  IC patient, two bladder biopsies were analyzed, one from an ulcer area (n=5, and one from a non-ulcer area (n=5). Patients samples were analyzed and compared with normal control urinary bladder biopsies. IC patients were evaluated according to the NIDDK criteria.
