95: Mitochondria transfer: biotech strategies and clinical hurdles

Kubat GB et al., Nature Communications - This Perspective surveys recent biotechnological advances that enhance mitochondria transfer and transplantation (MTT) — including surface functionalization, extracellular and engineered vesicles, hydrogels and nanomotors — and evaluates their therapeutic promise and limitations across cardiac, neural and other models. Key terms: mitochondrial transplantation, nanotechnology, extracellular vesicles, delivery systems, therapeutic potential. Study Highlights:The article reviews delivery strategies (CPPs, TPP/dextran coatings, EVs, liposomes, hydrogels, nanomotors) that increase mitochondrial protection, cellular uptake and tissue targeting in preclinical models. Encapsulation in EVs or lipid bilayers preserves mitochondrial integrity under Ca2+ and oxidative stress and improves functional rescue compared with naked mitochondria. Key translational barriers include immune activation, short post-isolation mitochondrial lifespan, low targeting efficiency across barriers like the BBB, and scalability and regulatory challenges. Conclusion:Biotechnology-enabled delivery systems substantially improve MTT efficacy in preclinical settings, but immune, mechanistic, scalability and safety issues must be resolved before routine clinical use.
