Background: In the setting of fibrogenic lesions, TGF-β1 drives cells to the myofibroblast phenotype and thereby causes excessive extracellular matrix (ECM) deposition. In the liver – as well as in other organs–BMP-7 has been described as an antifibrotic ligand abrogating profibrogenic TGF-β1 responses [1]. However, the exact molecular details of this antagonism have not been elucidated so far. To do so we employed a model system – L6E9 myoblasts – which transit into a myofibroblastic phenotype upon treatment with TGF-β1 [2]. In addition, we have already shown that in L6E9- myoblasts TGF-β1 responses are counter…
