mitochondria + MSC-derived exosomes

Mitochondria + MSC-derived exosomes is a combination therapy in which mitochondria or mitochondrial components are loaded into or co-delivered with mesenchymal stem cell (MSC)-derived exosomes. Exosomes are small extracellular vesicles secreted by cells, including MSCs, and serve as carriers for proteins, lipids, nucleic acids (including miRNAs), and organelles such as mitochondria. This combination leverages the natural intercellular communication and cargo delivery properties of exosomes to transfer functional mitochondria or their components to recipient cells. The mechanism of action involves the internalization of these engineered exosomes by target cells—such as macrophages—via endocytosis. Once inside the recipient cell, the delivered mitochondrial material can integrate with endogenous mitochondria, improving cellular bioenergetics (e.g., oxidative phosphorylation), reducing oxidative stress, modulating immune responses (e.g., promoting anti-inflammatory M2 macrophage polarization), and enhancing tissue repair processes. This approach has shown promise in preclinical models for conditions such as acute lung injury and cardiovascular diseases by restoring mitochondrial function in damaged tissues[2][3][1].
