What was done
This review synthesized current literature on intercellular mitochondrial transfer mechanisms, focusing on tunneling nanotube-mediated direct contact and extracellular vesicle-mediated indirect transport. The authors categorized four donor-recipient pairing modes and proposed a framework of five determinants governing transfer efficiency and functional outcomes: donor mitochondrial quality, donor transfer capacity, recipient metabolic demand, recipient integration capacity, and donor-recipient compatibility.
What was found
The abstract reports no numerical data or quantitative effect sizes. It describes qualitative functional diversity in metabolic support, tissue repair, and stress responses, noting that mitochondrial transfer can support tissue regeneration and functional recovery or, in certain microenvironments, drive pathological reprogramming.
Why it matters
Intercellular mitochondrial transfer is increasingly studied for regenerative medicine, aging interventions, and cancer therapies. This paper provides a conceptual donor-recipient framework to explain context-dependent beneficial versus detrimental outcomes.
Limits
As a narrative review, it presents no new experimental or human clinical data. The abstract does not define quantitative thresholds for compatibility or transfer efficiency, and translational applications remain conceptual.
