Abstract
One approach to tissue-engineering combines isolated cells with polymer scaffolds for the purpose of generating new tissue or tissue equivalents. It has met with much success when applied to the formation of new cartilage (neo-cartilage). In this review, we will examine the development of polyglycolic acid fiber meshes and calcium alginate gels that when combined with chondrocytes generate new cartilage. Animal models designed to mimic clinical problems will also be discussed. Using the chondrocyte–polymer systems as paradigms, we will attempt to extract some principles of tissue engineering.
