Extracellular matrix protein coatings for facilitation of urothelial cell attachment.
2007
Synthetic urothelium is an important goal for the tissue-engineering field that would have great utility for treating diseases and congenital defects affecting the urinary tract. A key step in the development of synthetic tissue is optimizing the conditions for coating biomaterials with cells of interest. Initial cell attachment is an important consideration when designing tissue-engineering scaffolds. The scaffold environment must also be conducive to cell proliferation and differentiation. The most popular materials for tissue-engineering scaffold often have suboptimal properties when analyzed for cell attachment and growth. It would then be of interest to know, for urinary tract tissue-engineering applications, which extracellular matrix protein coatings can facilitate urothelial cell attachment and encourage growth. Cells grown on 96-well cycloolefin plates coated with type IV or type I collagen exhibited improved initial attachment over plates coated with fibronectin or laminin. After 20 h, deoxyribo...
