Abstract Tonia Vincent's group has previously shown that the cartilage matrix releases sequestered growth factors, including FGF2 and latent TGFbeta, in response to mechanical injury. Latent TGFbeta requires the cell surface receptor, betaglycan, also known as TGFbetaR3 in order to become activated. Repair of the cartilage in vivo is dependent on FGF2 as mice deficient in this growth factor are unable to fill a cartilage defect compared with a control strain of mouse. Whilst examining the effect of FGF2 on mesenchymal stem cell (MSC) behavior in vitro her group found that FGF2 dramatically increased mobility of MSCs in the monolayer scratch assay but inhibited differentiation to the chondrocyte lineage in a 21 day chondrogenesis assay. The hypothesis that we would like to test is that FGF2 released upon articular cartilage injury primes MSCs for subsequent activation of latent TGFbeta by regulation of TGFbetaR3. (AU) | |
