Single-nucleus RNA-seq on undifferentiated human KD3 myoblasts and differentiated myotubes and mononucleated cells.

ABSTRACT: We report the application of single-nucleus-based sequencing technology for high-throughput profiling of transcriptome in immortazalized human myoblast KD3. By obtaining over sixty billion bases of sequence from mRNA, we generated comprehensive transcriptome profiles from KD3 undifferentiated myoblast and differentiated multi-nucleated myotube and mono-nucleated cells. We find that the data from single-nucleus RNA-seq is consistent with the transcriptome from single-cell RNA-seq. The pri-mRNA expression characterized by single-nucleus RNA-seq can reflect the actual miRNA level in the whole cell.

Expression profiling FSHD vs. control myoblasts and myotubes

Project description:The gene expression pathways leading to muscle pathology in facioscapulohumeral dystrophy (FSHD) remain to be elucidated. This muscular dystrophy is caused by a contraction of an array of tandem 3.3-kb repeats (D4Z4) at 4q35.2. We compared expression of control and FSHD myoblasts and myotubes (three preparations each) on exon microarrays (Affymetrix Human Exon 1.0 ST) and validated FSHD-specific differences for representative genes by qRT-PCR on additional myoblast cell strains. The FSHD and control myoblasts used for these experiments were shown to grow and differentiate into myotubes equally efficiently as control myoblasts. There were no significant FSHD-control differences in RNA levels for MYOD1 and MYOG at the myoblast and myotube stages and for MYF5 and MYF6 at the myoblast stage. In contrast, 295 other genes were dysregulated at least 2-fold in FSHD vs. control myoblasts (p <0.01, adjusted for multiple comparisons). Remarkably, only 10% of the FSHD-associated gene dysregulation at the myoblast stage was downregulation. At the myotube stage, about ten times as many genes exhibited FSHD-associated downregulated as at the myoblast stage and twice as many genes displayed FSHD-associated upregulation. The FSHD-related changes in RNA levels appear to be due to posttranscriptional as well as transcriptional alterations. Among the prominently dysregulated pathways were signaling and oxidative stress pathways. By comparing expression profiles of control myoblasts and myotubes to each other and to 19 non-muscle cell types profiled identically, our study also revealed many new myogenesis associations for genes not previously annotated as muscle-specific.

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

Project description: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.

Expression data from untreated vs. BMP4-treated cultured wild-type and MuSK null muscle cells (myoblasts and myotubes)

Project description:Bone morphogenic proteins (BMPs) function in virtually all tissues with cell-type specific outcomes. Since there are a relatively small number of BMP receptors this exquisite signaling specificity requires additional molecules to regulate the output of this pathway. We demonstrated that the receptor tyrosine kinase MuSK that is selectively expressed in muscle and plays a critical role in synapse formation and maintenance binds to BMP4 and related BMPs. Since BMPs regulate the transcription of a set of genes, we performed microarrays for wild-type and MuSK null muscle cells to test if MuSK regulates BMP responses in muscle cells. We shought to determine if MuSK regulates BMP responses in muscle cells and if the cell context made any difference in MuSK regulation of BMP pathway. To test this, expression profiles of untreated vs. BMP4-treated undifferentiated myoblast and differentiated myotube cultures were generated for both wild-type and MuSK-null genotypes. All conditions were done in triplicates. In total 24 arrays were analyzed.

Expression data from C2C12 myotubes infected with adenovirus expressing Gli1

Project description:We sought to determine the effects of over-expression of Gli1 on gene expression in C2C12 myotube cultures. C2C12 myoblasts were induced to differentiate for 4 days. At that time, when >80% of nuclei were incorporated into multi-nucleated syncitial myotubes, we infected the cultures with recombinant adenovirus expressing GFP alone or GFP and a full length human Gli1. Media was changed 12 hours later. Cultures were lysed 60 hours after the initial infection. Gli1 over-expression induces de-differentiation of myotubes and proliferation of myoblasts.

Transcriptome changes during the differentiation of myoblasts into myotubes

Project description:This study aimed to interrogate the interrelationship between 3D genome organization and global gene expression during muscle development using a mouse C2C12 cell line as an in vitro model. The C2C12 cell line is a well-established and extensively studied in vitro model derived from serial passage of myoblasts cultured from the thigh muscle of C3H mice after a crush injury. C2C12 cells divide when mitogens are present in the culture medium and spontaneously differentiate into muscle-like multinucleated (myotubes) cells if the medium is depleted of mitogens (i.e. serum; (Bischoff 1986)). C2C12 cells were either harvested as: 1) proliferating myoblasts (Myoblasts); 2) myotubes that were not treated with AraC (as such these myotubes contained myoblasts) - Myotubes(Day3); or 3) myotubes which were treated with AraC (myoblasts were largely depleted from these myotube cultures; Myotubes(Day7+AraC).
