Cell/Extracellular Matrix Interactions During Embryonic Development: Our lab is currently investigating the role of the matrix chondroitin sulfate proteoglycan, versican, during formation of the skeletal template and synovial joints in the embryonic limb. Using a variety of constructs to knock down expression or over-express specific domains and isoforms of versican we hope to ascertain its function during early development of the appendicular skeleton.
