Purpose of the Study:

• To critically evaluate the utility of IONPs in enhancing the detection and therapeutic applications of mesenchymal stem cells.
• To provide a comprehensive overview of IONP-based MSC labeling strategies for regenerative medicine and clinical practice.
• To collate and analyze existing studies on IONP-labeled MSCs across various sources and applications.

Main Methods:

• Systematic review and critical evaluation of in-vitro, animal, and clinical studies involving IONP-labeled MSCs.
• Analysis of IONP-induced intracellular alterations and their impact on MSCs.
• Compilation of studies utilizing various IONP combinations with biomaterials, elements, and therapeutic agents.

Main Results:

• IONP labeling effectively enhances MSC detection and tracking, showing promise in various preclinical and clinical settings.
• Diverse IONP labeling strategies, including combinations with carbohydrates, polymers, and other elements, have been explored.
• IONP-labeled MSC exosomes also demonstrate potential for therapeutic applications.

Conclusions:

• IONPs are a valuable tool for improving the clinical translation of MSC-based therapies by enabling reliable cell tracking and potentially enhancing therapeutic outcomes.
