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

ABSTRACT: 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.

Gene expression profiling of CHIR99021-induced skeletal myogenesis in human pluripotent stem cells

Project description:Human pluripotent stem cell- (hPSC)-derived skeletal muscle progenitors (SMP)—defined as PAX7-expressing cells with myogenic potential—can provide an abundant source of donor material for muscle stem cell therapy owing to the near-infinite replication potential of PSCs. As in vitro myogenesis is decoupled from in vivo timing and the 3D-embryo structure, it remains difficult to definitively characterize what stage or type of muscle is modeled in culture. Here, gene expression profiling is analyzed in hPSCs over a 50 day skeletal myogenesis protocol and compared to gene expression datasets of other hPSC-derived skeletal muscle and adult murine satellite cells. Furthermore, day 2 cultures differentiated with high or lower concentrations of CHIR99021 were contrasted. Expression profiling of the 50 day time course identified successively expressed gene subsets involved in mesoderm/paraxial mesoderm induction, somitogenesis, and skeletal muscle commitment/formation which could be regulative by a putative cascade of transcription factors. Initiating differentiation with higher CHIR99021 concentrations resulted in significantly higher expression of MSGN1 and TGFB-superfamily genes, notably NODAL, resulting in enhanced paraxial mesoderm and reduced ectoderm/neuronal gene expression. Comparison to adult satellite cells revealed that genes expressed in day 50 cultures correlated better with those expressed by quiescent or early activated satellite cells, which have a greater therapeutic potential than late activated satellite cells. Day 50 cultures were similar to other hPSC-derived skeletal muscle and both expressed known and novel SMP surface proteins.

ERBB3 and NGFR mark distinct skeletal muscle progenitor cells in human development enabling enrichment and maturation of hPSC muscle

Project description:Abstract: Human pluripotent stem cells (hPSCs) can be directed to differentiate into skeletal muscle progenitor cells (SMPCs). However, the myogenic potential of hPSC-SMPCs compared to human fetal or adult satellite cells (Scs) remains unclear. This study demonstrates hPSC-SMPCs derived by commonly used protocols are functionally less mature than freshly-isolated human fetal or adult Scs. We utilized RNA-SEQ of human fetal Scs to identify differentially expressed genes including NGFR, ERBB3, which enriched for MYOD+ or PAX7+ cells. Furthermore, inhibition of TGFβ (TGFβi) improved hPSC-muscle maturation in three independent lines as measured by TEM and expression of myosins. Engraftment of CRISPR/Cas9-corrected Duchenne Muscular Dystrophy (DMD) hiPSC-SMPC subpopulations treated with TGFβi in vivo, increased dystrophin-positive fibers to levels of engrafted cultured fetal Scs in mdx mouse models of DMD. This work provides the first characterization of the developmental status of hPSC-SMPCs and identifies candidates to enable robust myogenic activity in vitro and in vivo.

Zeb2 regulates myogenic differentiation in pluripotent stem cells

Project description:Zinc finger E-box-binding homeobox 2 (ZEB2, also known as SMAD interacting protein 1 or Zfhx1b) protein is a transcription factor involved in the transforming growth factor β (TGFβ) and bone morphogenetic proteins (BMPs) signaling pathways. ZEB2 is a two-handed zinc-finger closely related to ZEB1 (ZFHX1a/δEF1) and it is present in many tissues including cardiac and skeletal muscles. Skeletal muscle development and adult myogenesis are regulated by helix-loop-helix proteins, including MyoD, Myf5, myogenin and MRF-4. It has been shown that ZEB1 (ZFHX1a/δEF1) competes with the myogenic regulatory factors for their consensus sequences on some target genes during muscle differentiation, however the role of ZEB2 in myogenesis is still unknown. In the present study, we evaluated the myogenic potential of Zeb2-null and R26_Zeb2 mouse embryonic stem cells by single-cell RNA-sequencing and tested muscle engraftment capability of the respective myogenic progenitors. Our results support the implication of Zeb2 in promoting myogenesis in pluripotent stem cells and myogenic progenitors by modulating specific genes encoding components of the TGFβ/BMP signaling system.

Transcriptional landscape of human myogenesis reavels a key role of TWIST1 in maintenance of skeletal muscle progenitors

Project description:Derivation of human skeletal muscle in vitro with human pluripotent stem cells (hPSCs) opens new avenues for deciphering essential, but poorly understood aspects of transcriptional regulation in myogenic specification and relevance to rare genetic diseases. We characterized the transcriptional landscape of distinct human myogenic stages, including OCT4::EGFP+ PSCs, MSGN1::EGFP+ presomites, PAX7::EGFP+ skeletal muscle progenitors, MYOG::EGFP+ myoblasts, and multinucleated myotubes. We defined signature gene expression profiles from each population with unbiased clustering analysis, which provided unique insights into the transcriptional dynamics of human myogenesis from undifferentiated hPSCs to fully differentiated myotubes. Using knock-out strategy, we identified TWIST1 as a critical factor in maintenance of human PAX7::EGFP+ putative skeletal muscle progenitors, providing an explanation for the musculoskeletal symptoms of a rare genetic disease, Saethre-Chotzen syndrome. We have established a foundation for future studies to identify regulators of human myogenic ontogeny.

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.

lnc-mg is a long non-coding RNA that promotes myogenesis [lncRNA]

Project description:Recent studies have indicated important roles for long noncoding RNAs (lncRNAs) as potential essential regulators of myogenesis and adult skeletal muscle regeneration. However, in vivo, the role and mechanism of lncRNAs in myogenic differentiation of adult skeletal muscle stem cells (MuSCs) and myogenesis are still largely unknown. Here, we identified a skeletal muscle specific-enriched lncRNA (myogenesis-associated lncRNA, short for lnc-mg). In vivo, skeletal muscle conditional knockout of lnc-mg resulted in muscle atrophy and the loss of muscular endurance during exercise. Alternatively, skeletal muscle-specific overexpression of lnc-mg promoted muscle hypertrophy in mice. In vitro analyses of primary skeletal muscle cells isolated from mice showed that expression of lnc-mg was increased gradually during myogenic differentiation and overexpressed lnc-mg improved cell differentiation. Mechanistically, lnc-mg promoted myogenesis, by functioning as a competing endogenous RNA (ceRNA) for miR-125b to control protein abundance of Igf2. These findings identify lnc-mg as a novel and important noncoding regulator for muscle cell differentiation and skeletal muscle development. In order to identify functional lncRNAs correlating with myogenesis, microarrays were performed to detect the lncRNAs expression profile in undifferentiated MuSCs (GM, growth media/GM) ) and differentiated MuSCs (DM, differentiation media/DM).

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.

Single Cell sequencing of mononuclear cells from regenerating skeletal muscle

Project description:Skeletal muscle stem cells, or satellite cells (SCs), are essential to regenerate and maintain muscle. Quiescent SCs reside in an asymmetric niche between the basal lamina and myofiber membrane. To repair muscle, SCs activate, proliferate, and differentiate, fusing to repair myofibers or reacquiring quiescence to replenish the SC niche. Little is known about when SCs reacquire quiescence during regeneration or the cellular processes that direct SC fate decisions and progression through myogenesis. Single cell sequencing of myogenic cells in regenerating muscle identifies SCs reacquiring quiescence and reveals that non-cell autonomous signaling networks influence SC fate decisions during regeneration. Single cell RNA-sequencing of regenerating skeletal muscle reveals that RBP expression, including numerous neuromuscular disease-associated RBPs, is temporally regulated in skeletal muscle stem cells and correlates to stages of myogenic differentiation. By combining machine learning with RBP engagement scoring, we discover that the neuromuscular disease associated RBP Hnrnpa2b1 is a differentiation-specifying regulator of myogenesis controlling myogenic cell fate transitions during terminal differentiation.

A Unique Twist-Dependent Progenitor Cell Contributes to Adult Skeletal Muscle [Tw2 overexpression]

Project description:Skeletal muscle possesses remarkable regenerative potential due to satellite cells, a stem cell population located beneath the muscle basal lamina. By lineage tracing of progenitor cells expressing the Twist2 (Tw2) transcription factor in mice, we discovered a unique myogenic lineage that resides outside the basal lamina of adult muscle and contributes specifically to type IIb/x myofibers during adulthood and muscle regeneration. Tw2+ progenitors are molecularly and anatomically distinct from satellite cells, are highly myogenic in vitro and can fuse with satellite cells. Transplantation of Tw2+ progenitors into adult mice is sufficient to reconstitute new myofibers, and genetic ablation of endogenous Tw2+ progenitors causes wasting of type IIb myofibers. We show that Tw2 expression maintains progenitor cells in an undifferentiated state that is poised to initiate myogenesis in response to appropriate cues that suppress Tw2 expression. Tw2-expressing progenitors represent a previously unrecognized, fiber-type specific progenitor cell involved in muscle growth and regeneration.
