title: [In vitro stratified urothelium and its relevance in reconstructive urology].
abstract: There are two main objectives regarding tissue engineering in reconstructive urology: (1) to provide the surgeon with autologous tissue for urogenital reconstructive purposes and (2) to create the framework for experimental investigations to better understand the structure and function of the tissues involved. In the last years urothelial cell culture has become a routine laboratory technique. There is sufficient cellular output after isolation and propagation to seed cells as single cell suspensions on biodegradable matrices for the construction of cell-matrix implants. In recent publications attention was directed toward using established primary cell cultures for in vitro stratification of multilayered urothelial sheets. Urothelial sheets have been used quite successfully for covering acellular matrices for bladder augmentation in dog and minipig models. However, up to now there has been no clinical application in humans of urothelial sheets generated in vitro. Here we review facts about the different strategies for generating multilayered urothelial sheets.
