They received 38,879 citations and an average of 45.69 citations per publication. Annual output increased markedly after 2018 and peaked in 2025. China and the USA were the leading contributors. Journal, co-citation, and keyword analyses showed that mitochondria transfer research has expanded from mitochondrial biology, stem cell\u2013mediated repair, and cellular metabolism toward immune regulation, inflammation, tumor microenvironment remodeling, biomaterials, and translational medicine. Major knowledge bases and emerging hotspots included tunneling nanotubes, extracellular vesicles, mitochondrial transplantation, mitochondrial quality control, metabolic homeostasis, macrophages, T cells, B cells, immune evasion, macrophage polarization, and cGAS\/STING-related mechanisms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Mitochondria transfer has developed into an interdisciplinary field connecting cellular mechanisms, immune\u2013inflammatory regulation, disease microenvironment remodeling, and translational therapy.
