Transcriptomic profile of hiPSC-derived myoblasts and myotubes coated on distinct substrates

ABSTRACT: Driving efficient and pure skeletal muscle cell differentiation from pluripotent stem cells has been challenging. Here, we report an optimized protocol that generates skeletal muscle progenitor cells with high efficiency and purity, in a short period of time. Human induced pluripotent stem cells (hiPSC) and mouse embryonic stem cells (mESC) were specified into the mesodermal myogenic fate using distinct and species-specific protocols. We used a specific Maturation Medium to promote terminal differentiation of both human and mouse myoblast populations, and generated myotubes associated with a large pool of cell cycle-arrested PAX7+ cells. We further show that myotube maturation is modulated by the dish coating properties, cell density and percentage of myogenic progenitor cells. Given the high efficiency in the generation of myogenic progenitors and differentiated myofibers, this protocol provides an attractive strategy for tissue engineering, modeling of muscle dystrophies and evaluation of new therapeutic approaches in vitro.

Highly contractile 3D tissue engineered skeletal muscles from human iPSCs reveal similarities with primary myoblast-derived tissues

Project description:Skeletal muscle research is transitioning towards 3D tissue engineered in vitro models reproducing muscle’s native architecture and supporting measurement of functionality. Human induced pluripotent stem cells (hiPSCs) offer high yields of cells for differentiation. It has been difficult to differentiate high quality, pure 3D muscle tissues from hiPSCs that show contractile properties comparable to primary myoblast-derived tissues. Here, we present a transgene-free method for the generation of purified, expandable myogenic progenitors (MPs) from hiPSCs grown under feeder-free conditions. We defined a protocol with optimal hydrogel and medium conditions that allowed production of highly contractile 3D tissue engineered skeletal muscles with forces similar to primary myoblast-derived tissues. Gene expression and proteomic analysis between hiPSC-derived and primary myoblast-derived 3D tissues revealed a similar expression profile of proteins involved in myogenic differentiation and sarcomere function. The protocol should be generally applicable for the study of personalized human skeletal muscle tissue in health and disease.

Extracellular vesicle-derived miRNAs improve stem cell-based therapeutic approaches in muscle wasting conditions.

Project description:Skeletal muscle holds an intrinsic capability of growth and regeneration both in physiological conditions and in case of injury. Chronic muscle illnesses, generally caused by genetic and acquired factors, lead to deconditioning of the skeletal muscle structure and function, and are associated with a significant loss in muscle mass. At the same time, progressive muscle wasting is a hallmark of aging. Given the paracrine properties of myogenic stem cells, extracellular vesicle-derived signals have been studied for their potential implication in both the pathogenesis of degenerative neuromuscular diseases and as a possible therapeutic target. In this study, we screened the content of extracellular vesicles from animal models of muscle hypertrophy and muscle wasting associated with chronic disease and aging. Analysis of the transcriptome, protein cargo and microRNAs (miRNAs) allowed us to identify a hypertrophic miRNA signature amenable for targeting muscle wasting, consisting of miR-1 and miR-208a. We tested this signature among others in vitro on mesoangioblasts (MABs), vessel-associated adult stem cells, and we observed an increase in the efficiency of myogenic differentiation. Furthermore, injections of miRNA-treated MABs in aged mice resulted in an improvement in skeletal muscle features, such as muscle weight, strength and cross-sectional area compared to controls. Overall, we provide evidence that the extracellular vesicle-derived miRNA signature we identified enhances the myogenic potential of myogenic stem cells.

Defining the skeletal myogenic lineage in human pluripotent stem cell-derived teratomas

Project description:Skeletal muscle stem cells are essential to muscle homeostasis and regeneration after injury. An attractive approach to obtain these cells is via differentiation of pluripotent stem cells (PSCs). We have recently reported that teratomas derived from mouse PSCs are a rich source of skeletal muscle stem cells. Here, we showed that the teratoma formation method is also capable of producing skeletal myogenic progenitors from human PSCs. Using single-cell transcriptomics, we discovered multiple lineages in human PSC-derived teratomas. Interestingly, we observed several distinct skeletal myogenic subpopulations. Trajectory analysis revealed that these subpopulations represented progressive stages of skeletal myogenic development. We further discovered that ERBB3 and CD82 are effective surface markers for prospective isolation of the skeletal myogenic lineage in human PSC-derived teratomas. Therefore, teratoma formation provides an accessible model for obtaining human skeletal myogenic progenitors from PSCs.

Cellular and transcriptomic changes by the supplementation of aged rat serum in human pluripotent stem cell-derived myogenic progenitors

Project description:Introduction: The changing composition of non-cell autonomous circulating factors in blood as humans age is believed to play a role in muscle mass and strength loss. The mechanisms through which these circulating factors act in age-related skeletal muscle changes is not fully understood. In this study, we used human myogenic progenitors derived from human pluripotent stem cells to study non-cell autonomous roles of circulating factors during the process of myogenic differentiation. Methods: Myogenic progenitors from human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) were supplemented with serum samples from aged or young Fischer 344 × Brown Norway F1-hybrid rats. The effect of aged or young serum supplementation on myogenic progenitor proliferation, myotube formation capacity, differentiation, and early transcriptomic profiles were analyzed. Results: We found that aged rat serum supplementation significantly reduced cell proliferation and increased cell death in both ESC- and iPSC-derived myogenic progenitors. Next, we found that the supplementation of aged rat serum inhibited myotube formation and maturation during terminal differentiation from progenitors to skeletal myocytes when compared to the cells treated with young adult rat serum. Lastly, we identified that gene expression profiles were affected following serum supplementation in culture. Discussion: Together, aged serum supplementation caused cellular and transcriptomic changes in human myogenic progenitors. The current data from our in vitro model possibly simulate non-cell autonomous contributions of blood composition to age-related processes in human skeletal muscle.

Comparative analysis of the proteome and transcriptome transition in goat skeletal muscle stem cells, myoblast and myotube

Project description:Enhancing the proliferation and myogenic commitment of progenitor cells during fetal development enhances muscle growth and lean production in offspring. During the early development, a pool of skeletal stem cells (SSCs) proliferates and then diverge into either myoblast. Myoblast further fusion and develop into myotube. However, the landscape from muscle stem cells to myotubes in goats is not yet clear. This study aims to characterize the changes in the expression profile of skeletal muscle stem cells that differentiate into myoblasts, then migrate and fuse to form myotubes.

Single Cell RNA-Sequencing of Human Limb Skeletal Muscle across Development and Myogenic Culture from Pluripotent Stem Cells

Project description:The developmental trajectory of human skeletal myogenesis and the transition between progenitor and stem cell states are unclear. To address this, we employed single cell RNA-sequencing to profile human skeletal muscle tissues from embryonic, fetal and postnatal stages. In silico, we identified myogenic as well as other cell types and constructed a “roadmap” of human skeletal muscle ontogeny across development. In a similar fashion, we also profiled the heterogeneous cell cultures generated from multiple human pluripotent stem cell (hPSC) myogenic differentiation protocols, and mapped hPSC-derived myogenic progenitors to an embryonic-to-fetal transition period. Additionally, we found differentially enriched biological processes and discovered co-regulated gene networks and transcription factors present at distinct myogenic stages. In summary, this work serves as a resource for advancing our knowledge of human myogenesis. It also provides a tool for better characterization and understanding of hPSC-derived myogenic progenitors for translational applications in skeletal muscle based regenerative medicine.

Combinatorial small molecule treatment enhances the in vitro maturation of pluripotent stem cell-derived myotubes

Project description:Targeted differentiation of pluripotent stem (PS) cells into myotubes enables in vitro disease modeling of skeletal muscle diseases. Although various protocols achieve myogenic differentiation in vitro, resulting myotubes invariably display an embryonic identity. This is a major hurdle for accurately recapitulating disease phenotypes in vitro, as disease typically does not manifest in the embryonic muscle, but at more mature stages. To address this problem, we identified four factors from a small molecule screen whose combinatorial treatment resulted in myotubes with enhanced maturation, as shown by increased expression of fetal, neonatal and adult myosin heavy-chain isoforms. These molecular changes were confirmed by global chromatin accessibility and transcriptome studies. Importantly, we also observed this maturation in three-dimensional muscle bundles, which displayed improved in vitro contractile force generation in response to electrical stimulus. Thus, we established a model for in vitro muscle maturation from PS cells.

Human engineered skeletal muscle of hypaxial origin from pluripotent stem cells with advanced function and regenerative capacity

Project description:Human pluripotent stem cell derived muscle models show great potential for translational research. Here, we describe novel developmentally inspired methods for the derivation of skeletal muscle cells and their utility in three-dimensional skeletal muscle organoid formation as well as skeletal muscle tissue engineering. Three-dimensional organoid and tissue engineered models exhibit organotypic maturation and function and regenerative responses, recapitulating canonical properties of bona fide skeletal muscle in vivo. Key steps include the directed differentiation of human pluripotent stem cells to embryonic muscle progenitors of hypaxial origin followed by primary and secondary fetal myogenesis with development of a satellite cell pool and evidence for innervation in vitro. Regenerative competency was demonstrated in a cardiotoxin injury model with evidence for satellite cell activation as underlying mechanism.

Differentiation protocol assay on Mouse ES cell lines E14 129P2/OlaHsd

Project description:Stem cell-derived tissues have wide potential for modelling developmental and pathological processes as well as cell-based therapy. However, it has proven difficult to generate several key cell types in vitro, including skeletal muscle. In vertebrates, skeletal muscles derive during embryogenesis from the presomitic mesoderm (PSM). Treatment of mouse ES cells with a combination of the secreted Wnt activator R-Spondin3 and the BMP inhibitor Noggin generated cells expressing the early PSM marker Mesogenin1 (Msgn1) with high efficiency. To confirm their identity, we mapped gene expression profiles at successive stages of PSM differentiation in vivo and showed that the differentiated ES cells closely corresponded to the posterior PSM domain that expresses Msgn1 and then with time in culture matured to acquire the profile of the anterior Pax3 domain. When grafted into injured adult muscle in vivo these Pax3-expressing-cells generated large numbers of muscle fibers. Our system therefore efficiently produces myogenic precursors in vitro by recapitulating stepwise early myogenic differentiation in vivo. These findings should advance the development of cellular therapies for muscle degenerative diseases. ES cellline E14 129P2/OlaHsd with DMSO, Rspo, and Noggin at Days 3 and 4
