Summary
Jessica Krieger et al. clarify the role of TGF-β1 signaling in skeletal muscle myogenesis, and the specific roles of fibroblasts and myofibroblasts in myogenesis. In this study, they grow 2D and 3D monocultures and co-cultures with and without TGF-β1, and monitor changes in gene expression, cell phenotype, and elastic moduli of the tissues. The study finds 3D co-cultures of myoblasts and myofibroblasts treated with TGF-β1 are most effective at driving myogenesis and myotube formation to form the most stable, organized tissues. The results pertaining to the impacts of TGF-β1 are consistent with similar studies, though Krieger et al. acknowledge myofibroblasts are superior to fibroblasts in driving myotube formation. Furthermore, Krieger et al. show the use of a hydrogel-based system for helping to scale-up this process. The study offers an attainable cell culture model for cultured meat production, highlighting that TGF-β1 treatment and co-culturing with myofibroblasts enhances myogenesis.
