Bone morphogenetic protein 7 (BMP-7) regulates cellular metabolism in embryonic and adult tissues. Signal transduction occurs through the activation of intracellular Smad proteins. In this paper, using a yeast two-hybrid screen, Smad1 was found to interact with the cytoplasmic domain of CD44, a receptor for the extracellular matrix macromolecule hyaluronan.(More)
Articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration potential. The scarcity of treatment modalities for large chondral defects has motivated attempts to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. Cartilage tissue engineering requires three components: cells,(More)
Hyaluronan-cell interactions are initiated co-ordinately with mesenchymal condensation during chondrogenic differentiation in the limb bud. Hyaluronan is responsible for the retention and organization of proteoglycan within the cartilage matrix. Hyaluronan-CD44 binding also retains proteoglycan aggregates to the chondrocyte plasma membrane. A sequence for(More)
