Cultured meat (CM) is derived from the in vitro myogenesis of muscle satellite (stem) cells (MSCs) and offers a promising alternative protein source. However, the development of a cost-effective media formulation that promotes cell growth has yet to be achieved. In this study, laxogenin (LAX) and 5-alpha-hydroxy-laxogenin (5HLAX) were computationally screened against myostatin (MSTN), a negative regulator of muscle mass, because of their antioxidant properties and dual roles as MSTN inhibitors and enhancers of myogenesis regulatory factors. In silico analysis showed LXG and 5HLXG bound to MSTN with binding free energies of −7.90 and −8.50 kcal/mol, respectively. At a concentration of 10 nM, LAX and 5HLAX effectively inhibited the mRNA and protein expressions of MSTN, promoted myogenesis, and enhanced myotube formation and maturation. In addition, by acting as agonists of ROS downregulating factors, they exhibited antioxidative effects. This study shows that supplementation with LAX or 5HLAX at 10 nM in CM production improves texture, quality, and nutritional value. We believe this study fills a research gap on media development for myotube formation and maturation, which are important factors for large-scale in vitro CM production that improve product quality, nutritional value, and efficacy.
