Summary

Many different novel approaches to tissue replacement or tissue regeneration can now be categorized as “tissue engineering.”This includes the use of cultured autologous cells, e.g., keratinocytes or chondrocytes to replace missing tissue. At the other extreme, the decellularization of tissue allografts produces matrices that stimulate regeneration while avoiding immunological rejection responses. Combining both cells and matrices, and conditioning the constructs in bioreactors, takes the technology a stage further. This chapter explores how these methods are being applied to improve the performance of current tissue grafts.
