Large-Scale Expansion of Human iPSC-Derived Skeletal Muscle Cells for Disease Modeling and Cell-Based Therapeutic Strategies

Abstract: SummaryAlthough skeletal muscle cells can be generated from human induced pluripotent stem cells (iPSCs), transgene-free protocols include only limited options for their purification and expansion. In this study, we found that fluorescence-activated cell sorting-purified myogenic progenitors generated from healthy controls and Pompe disease iPSCs can be robustly expanded as much as 5 × 1011-fold. At all steps during expansion, cells could be cryopreserved or differentiated into myotubes with a high fusion inde… Show more

“…Given these findings we propose that the ESM model may represent a versatile tool to (1) further dissect satellite cell biology, (2) establish skeletal muscle disease models in vitro for drug development, and (3) provide potential therapeutic satellite cells for cellbased skeletal muscle repair. The availability of human pluripotent stem cells and methods for their directed myoblast differentiation 58,59 will facilitate the translation of the reported rat to a human model. In fact, alternative models of engineered human skeletal muscle using the forced expression of Pax7 60 or directed multi-lineage differentiation in induced pluripotent stem cells 61 have recently been reported.…”

“…hiPSCs can be generated from the patient's somatic cells, and transplantation of hiPSC-derived cells do not induce immune rejection in the patient as in heterologous transplantation [155]. Furthermore, gene mutation can be corrected by genome editing technology in patient-derived iPSCs [159], and gene-corrected iPSC-derived cells may be ideal cell sources for regenerative therapy. In DMD, innovation is still necessary to develop the method to deliver the cells to whole body.…”

“…34,35 Correction of mutations in DMD cells could be achieved by CT followed by differentiation to muscle cells and their injection in the muscles, an option that has been used by several researchers in muscle pathology. 27,33,[36][37][38] The only needed additional step to the protocol used herein is the inactivation, before retro-MMCT fusion, of the HPRT gene on the endogenous X chromosome by CRISPR technology, allowing the use of HAT selection after retro-MMCT. We have recently shown the feasibility of this step by correcting the genetic defect in iPSCs from a mouse model of the X-linked CGD.…”
