Abstract
OBJECTIVE: For in vitro tissue engineering in urology, stem cells are commonly isolated from tissue specimens obtained during open or endoscopic surgery. Within the context of the present study our aim was to isolate cells from human urine by an alternative and safe technique rather than using the indicated method. MATERIAL AND METHODS: After human urine samples had been collected from young and healthy donors via urethral catheterization, cells were precipitated by centrifugation and cultured. Following this isolation procedure, cells were characterized by immunocytochemical method using specific antibodies. RESULTS: When these cells were characterized by immunocytochemical methods using specific antibodies some of them were positive for mesenchymal stem cell marker CD90 while the others were labelled with urothelial marker cytokeratin 7. When all these results were taken into consideration, urothelial cells together with stem cells were observed in the urine- derived cell population. CONCLUSION: According to the results obtained from this study human urine may be preferred as an alternative stem cell and urothelial cell source in that this method is and easily reproducible non-invasive method.
