ObjectivesMyoblast transfer therapy (MTT) is a technique to replace muscle satellite cells with genetically repaired or healthy myoblasts, to treat muscular dystrophies. However, clinical trials with human myoblasts were ineffective, showing almost no benefit with MTT. One important obstacle is the rapid senescence of human myoblasts. The main purpose of our study was to compare the various methods for scalable generation of proliferative human myoblasts.MethodsWe compared the immortalization of primary myoblasts with hTERT, cyclin D1 and CDK4R24C, two chemically defined methods for deriving myoblasts from pluripotent human embryonic stem cells (hESCs), and introduction of viral MyoD into hESC‐myoblasts.ResultsOur results show that, while all the strategies above are suboptimal at generating bona fide human myoblasts that can both proliferate and differentiate robustly, chemically defined hESC‐monolayer‐myoblasts show the most promise in differentiation potential.ConclusionsFurther efforts to optimize the chemically defined differentiation of hESC‐monolayer‐myoblasts would be the most promising strategy for the scalable generation of human myoblasts, for applications in MTT and high‐throughput drug screening.
