Tissue engineering entails the in vitro construction of bioartificial tissues as well as the in vivo manipulation of cell growth and function using cells isolated from donor tissue and biocompatible scaffold materials. To facilitate effective cell adhesion, migration, and deposition of endogenous extracellular matrix components by the cells, biomaterials for tissue engineering must have regulated surface chemistry, porosity, and biodegradability. To provide a large cell mass that can perform certain differentiated roles required for the tissue build, strategies to switch cells between growth and differentiation, which are mutually exclusive, are applied. The strength of adhesion between cells and substrate, as well as among the many cell types present in the tissue construct, allows combinations of cells and materials to reorganise themselves. Tissue engineering is not frequently used in the care or treatment of patients. Tissue engineering has been employed in skin transplants, cartilage repair, minor artery repair, and bladder repair in a few cases.
