Isolation and Biophysical Characterization of Extracellular Vesicles Released by Myocytes

Area of Science:

• Cell Biology
• Biochemistry
• Biotechnology

Background:

• Extracellular vesicles (EVs) are crucial mediators of intercellular communication, released by various cell types.
• Skeletal muscle acts as an endocrine organ, producing EVs that influence cellular processes.
• The C2C12 myocyte cell line is a valuable in vitro model for muscle research.

Purpose of the Study:

• To establish a robust protocol for isolating high-purity EVs from differentiated C2C12 myocytes.
• To provide a standardized workflow for characterizing muscle-derived EVs.
• To enable downstream applications for studying EV composition and function.

Main Methods:

• Isolation of EVs from differentiated C2C12 myocytes using sequential ultracentrifugation and size-exclusion chromatography.
• Characterization and validation of isolated EVs via western blotting.
• Transmission electron microscopy (TEM) and dynamic light scattering (DLS) analysis.

Main Results:

• A standardized protocol yielding high-purity extracellular vesicles from C2C12 myocytes was successfully developed.
• The isolated EVs were thoroughly validated using established biochemical and imaging techniques.
• The protocol generates EV samples suitable for diverse downstream analyses.

Conclusions:

• This workflow offers a reliable platform for investigating muscle-derived EVs.
• It facilitates comparative studies on EV composition and function under various conditions.
• This method supports research into the role of muscle EVs in health and disease.
