Unveiling Key Genes and Crucial Pathways in Goose Muscle Satellite Cell Biology Through Integrated Transcriptomic and...

Area of Science:

• Muscle stem cell biology
• Comparative genomics
• Metabolomics

Background:

• Skeletal muscle satellite cells (SMSCs) are vital for muscle repair and growth.
• Understanding goose SMSC differentiation is crucial but underexplored.
• This study investigates goose SMSCs across key differentiation stages.

Purpose of the Study:

• To elucidate the molecular and metabolic mechanisms of goose SMSC differentiation.
• To identify stage-specific signatures and regulatory networks.
• To provide insights into muscle development and regeneration in geese.

Main Methods:

• Morphological, transcriptomic, and metabolomic analyses of goose SMSCs.
• Principal component analysis of gene expression and metabolite profiles.
• Identification of key signaling pathways and gene expression patterns.

Main Results:

• Distinct molecular and metabolic profiles were observed across quiescent, differentiation, and late differentiation stages.
• The PPAR signaling pathway was identified as a key regulator.
• Specific genes (e.g., PPARG, IGF1) and metabolites showed dynamic expression and correlations.

Conclusions:

• Goose SMSC differentiation involves significant metabolic reprogramming, particularly in lipid metabolism.
• PPAR signaling plays a critical role in regulating goose myogenesis.
• Findings offer foundational knowledge for agricultural and biomedical applications in muscle biology.
