This review explores skeletal muscle development, detailing molecular regulators and cellular heterogeneity. Advances in single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) reveal conserved and species-specific mechanisms for cell fate regulation.
Area of Science:
- Developmental Biology
- Molecular Biology
- Cell Biology
Background:
- Skeletal muscle development is a complex, highly regulated biological process.
- Understanding cellular and molecular events is crucial for muscle development research.
- Recent technological advancements offer new insights into muscle dynamics.
Purpose of the Study:
- To review existing evidence on molecular components of skeletal muscle cellular heterogeneity.
- To elucidate the synergistic stabilization of transcription factor networks, epigenetic regulation, and metabolic reprogramming in cell fate.
- To compare conserved and species-specific regulatory features across different species.
Main Methods:
- Systematic review of evidence on skeletal muscle development.
- Analysis of single-cell RNA sequencing (scRNA-seq) data.
- Integration of spatial transcriptomics (ST) and multimodal data for microenvironment analysis.
Main Results:
- Identification of key molecular components driving cellular heterogeneity in skeletal muscle development.
- Elucidation of conserved and species-specific mechanisms in skeletal muscle development across humans, mice, pigs, and chickens.
- Understanding the microenvironment's role (niche composition, intercellular communication, mechanical cues) in regulating muscle stem cell (MuSC) behavior.
Conclusions:
- Discoveries elucidate fundamental principles of skeletal muscle development.
- Provides a theoretical basis for therapeutic strategies against muscle-related diseases.
- Offers insights for improving economically important traits in livestock breeding.
