TISSUE ENGINEERING What is tissue engineering? Production of tissue in vitro by growing cells in porous, absorbable scaffolds(matrices). Why is tissue engineering necessary Most tissues cannot regenerate when injured or diseased. Even tissues that can regenerate spontaneously may not completely do so in large defects(eg, bone). Replacement of tissue with permanent implants is greatly limited.TISSUE ENGINEERING TISSUE ENGINEERING What is tissue engineering?
