Human bladder carcinoma: characterization of two new tumor cell lines and search for tumor viruses.
Two newly established human bladder carcinoma cell lines, designated HT-1197 and HT-1376, were characterized. Cells of both cultures exhibited fine structural microvilli and tonofibrils indicative of their epithelial origin. In addition, desmosomes were also present in HT-1197. Marker chromosomes present in HT-1197 and HT-1376 distinguished these from each other and from other known human tumor cell lines. Both cultures grew in soft agar, induced fibrinolytic activity, and were tumorigenic in mice and hamsters. No type C or other virus expression was detected in these cell lines nor in other human urothelial tumors tested.
