[Development of Mesenchymal Stem Cell-derived Extracellular Vesicle Preparations for Practical Application].

Area of Science:

• Regenerative Medicine
• Cell Biology
• Biotechnology

Background:

• Mesenchymal stem cells (MSCs) are key in regenerative medicine due to multipotency and immunomodulation.
• MSC-derived extracellular vesicles (EVs) are emerging as a cell-free therapeutic alternative, mimicking parent cell effects.
• EVs offer a cell-free therapeutic modality with potential in various diseases.

Purpose of the Study:

• To review the current status and future prospects of MSC-derived EVs.
• To focus on therapeutic mechanisms, standardization, and regulatory trends.
• To discuss challenges and strategies for developing EV-based therapeutics.

Main Methods:

• Literature review of MSC-derived EV research.
• Analysis of therapeutic mechanisms and biological effects.
• Examination of standardization, manufacturing, quality control, and regulatory aspects.

Main Results:

• MSC-EVs show therapeutic potential similar to MSCs but as a cell-free product.
• Key challenges include scalable manufacturing, quality control, and viral safety.
• Quality by Design (QbD) and single-particle analytics are crucial for consistency.

Conclusions:

• MSC-EVs hold significant potential for treating refractory diseases.
• Harmonization of scientific, technical, and regulatory frameworks is essential for clinical translation.
• This review provides a comprehensive overview of the translational pathway for MSC-EV therapeutics.
