These stages can be manipulated by exogenous factors including signaling molecules, mechanical cues, and nutrient supplementation. Supplementation with bioactives, such as tomatidine, can improve aspects of skeletal muscle health when evaluated using in vitro and in vivo models. In this study, a phenotypic characterization of the effects of tomatidine supplementation during proliferation, early maturation and differentiation, was undertaken in C2C12 muscle cells, cultured in growth medium, or alternatively induced to differentiate in medium supplemented with 10\u2009\u00b5M tomatidine, for up to 4 days. Real\u2010time impedance assays indicated tomatidine slowed C2C12 proliferation after 3 days of supplementation. Tomatidine supplementation from the onset of differentiation induced myotube hypertrophy within the first 48 h of maturation. Tomatidine\u2010induced hypertrophy was driven by increased myonuclei fusion in developing myotubes with a concomitant increase in protein synthesis. Taken together, tomatidine's growth promoting effects on skeletal muscle cells identify its therapeutic potential for enhancing muscle regeneration and repair, by mechanisms that improve myofiber maturation and function.<\/jats:p>","DOI":"10.1002\/cbin.70224","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T13:16:47Z","timestamp":1791465407000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tomatidine Exposure During Early Myogenesis Promotes Hypertrophy of C2C12 Muscle Cells Through Increased Nuclei Accretion"],"prefix":"10.1002","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4447-9020","authenticated-orcid":false,"given":"Marissa K.","family":"Caldow","sequence":"first","affiliation":[{"name":"Centre for Muscle Research, Department of Anatomy and Physiology School of Biomedical Sciences, Faculty of Medicine, Dentistry and Health Sciences, The University of Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2509-4619","authenticated-orcid":false,"given":"Kristy","family":"Swiderski","sequence":"additional","affiliation":[{"name":"Centre for Muscle Research, Department of Anatomy and Physiology School of Biomedical Sciences, Faculty of Medicine, Dentistry and Health Sciences, The University of Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6654-386X","authenticated-orcid":false,"given":"John H.
