  • Patent number: 6232289
    Abstract: Interstitial cystitis (IC) is a chronic bladder disease for which the exact etiology is unknown and for which there is no reliably effective treatment. However, it is known that the bladder epithelium is often abnormal in IC. We discovered that human bladder epithelial cells from both normal controls and IC patients are inhibited from proliferating by an anti-proliferative factor (APF) present in IC urine specimens. Inhibited proliferation may cause epithelial abnormalities characteristic of IC such as ulcerations and multiple tears in the bladder epithelium.
