Abstract

One of the main topics of regenerative medicine and tissue engineering is to address the problem of lesions involving articular cartilage. In fact, these lesions do not heal spontaneously and often lead to osteoarthritis, which causes chronic pain and worsens quality of life. Moreover, the only available treatment for osteoarthritis is symptomatic therapy and prosthetic replacement, with far from satisfactory results. A more conservative approach that restores the articular surface and function with a biologic tissue is desirable. Several strategies for regenerating articular cartilage have been proposed and applied in clinical practice but a gold standard has not yet been identified. Biphasic composites are the latest products of tissue engineering applied to articular cartilage and they seem to permit a more efficient integration of the engineered neo-tissue with the host. We present an in vitro tissue engineered model for osteochondral repair based on a composite of chondrocytes-fibrin glue gel and a calciumphosphate scaffold. This composite showed a gross integration of the two components and a cartilage-like quality of the newly formed matrix. Further studies are planned to quantify the adherence between the scaffold and the cellular fibrin glue.
