TISSUE ENGINEERING, based on the use of synthetic biodegradable polymer cell delivery vehicles (scaffolds), was introduced in 1988 by Vacanti et al¹ as an alternate treatment modality for replacing missing cartilage. By virtue of the ability to maintain their original 3-dimensional shape, homopolymers of polyglycolic acid were configured into branching networks of thin fibers, coated with a solvent-based poly-L-lactic acid suspension, molded into the shape of a human ear, impregnated with a large population of bovine-derived articular chondrocytes, and implanted subcutaneously on the dorsum of athymic mice. These cell-polymer constructs reportedly generated cartilage analogues, which approximated the biochemical and biomechanical properties of articular cartilage in 6 to 12 weeks of in vivo time, respectively. Other more recent animal-based in vivo and in vitro studies using 3-dimensional cell culture paradigms^2-3 predict that tailor-made cartilage substitutes for craniofacial augmentation, joint resurfacing, and tracheal replacement are not too far from clinical realization.
