By examining the phenotypic plasticity of cartilage and tendon cells, researchers found that oxidative stress and P13K signaling pathways are key modulators of the phenotype of musculoskeletal cells. Using monolayer and three-dimensional cultures, the experiments confirmed that dedifferentiation occurs via reductions in expression of genes for cartilage (Col2a1, Agcn) and tendon (Tnmd, Serpinf1)…
