Mitochondria Transfer in Mesenchymal Stem Cells: Unraveling the Mechanism and Therapeutic Potential

Mesenchymal stem cells (MSCs) hold transformative potential in translational medicine due to their versatile differentiation abilities and regenerative properties. Notably, MSCs can transfer mitochondria to unrelated cells through intercellular mitochondrial transfer, offering a groundbreaking approach to halting the progression of mitochondrial diseases and restoring function to cells compromised by mitochondrial dysfunction. Although MSC mitochondrial transfer has demonstrated significant therapeutic promise across a range of diseases, its application in clinical settings remains largely unexplored. This review delves into the novel mechanisms by which MSCs execute mitochondrial transfer, highlighting its profound impact on cellular metabolism, immune modulation, and tissue regeneration. We provide an in-depth analysis of the therapeutic potential of MSC mitochondrial transfer, particularly in treating mitochondrial dysfunction-related diseases and advancing tissue repair strategies. Additionally, we propose innovative considerations for optimizing MSC mitochondrial transfer in clinical trials, emphasizing its potential to reshape the landscape of regenerative medicine and therapeutic interventions.
