Abstract:
Bladder tissue engineering includes three components, namely cell scaffold, seeding cells and message factor. Seeding cells is essential to construct tissue engineering organs and is the native material of organ reconstruction. It is important to find a seeding cell which can not only provide excellent biocompatibility, but also can generate enough cells in work of organ reconstruction. At present, there are some commonly used seeding cells, for example, urinary bladder transitional epithelial cells,smooth muscle cells, coculture of smooth muscle cells and transitional epithelial cells, mesenchymal stem cells. Among the total,coculture of smooth muscle cells and transitional epithelial cells and mesenchymal stern cells are better than the others. The current problems of seeding cells are as follows: ①The mature cells that have been completely differentiated are limited in source and immunological rejection. ② The mature cells that have been completely differentiated during the differentiated only can generate in the limited passage culture procedure and they will age and die out of the passage maximum; in addition, the dedifferentiation also exists; ③further analysis should focus on the coculture of smooth muscle cells and transitional epithelial cells and mesenchymal stem cells into normal bladder.
