In this study, the safety and efficacy of autologous mitochondrial transplantation by intra-arterial injection for renal protection in a swine model of bilateral renal ischemia-reperfusion injury were investigated. Female Yorkshire pigs underwent percutaneous bilateral temporary occlusion of the renal arteries with balloon catheters. Following 60 min of ischemia, the balloon catheters were deflated and animals received either autologous mitochondria suspended in vehicle or vehicle alone, delivered as a single bolus to the renal arteries. The injected mitochondria were rapidly taken up by the kidney and were distributed throughout the tubular epithelium of the cortex and medulla. There were no safety-related issues detected with mitochondrial transplantation. Following 24 h of reperfusion, estimated glomerular filtration rate and urine output were significantly increased while serum creatinine and blood urea nitrogen were significantly decreased in swine that received mitochondria compared with those that received vehicle. Gross anatomy, histopathological analysis, acute tubular necrosis scoring, and transmission electron microscopy showed that the renal cortex of the vehicle-treated group had extensive coagulative necrosis of primarily proximal tubules, while the mitochondrial transplanted kidney showed only patchy mild acute tubular injury. Renal cortex IL-6 expression was significantly increased in vehicle-treated kidneys compared with the kidneys that received mitochondrial transplantation. These results demonstrate that mitochondrial transplantation by intra-arterial injection provides renal protection from ischemia-reperfusion injury, significantly enhancing renal function and reducing renal damage.<\/jats:p>","DOI":"10.1152\/ajprenal.00255.2020","type":"journal-article","created":{"date-parts":[[2020,7,20]],"date-time":"2020-07-20T06:59:10Z","timestamp":1595228350000},"page":"F403-F413","source":"Crossref","is-referenced-by-count":105,"title":["Mitochondrial transplantation by intra-arterial injection for acute kidney injury"],"prefix":"10.1152","volume":"319","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4128-7111","authenticated-orcid":false,"given":"Ilias P.","family":"Doulamis","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alvise","family":"Guariento","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Duignan","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Kido","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arzoo","family":"Orfany","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mossab Y.","family":"Saeed","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viktoria H.","family":"Weixler","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Blitzer","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Borami","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Boston Children\u2019s Hospital, Department of Surgery, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erin R.","family":"Snay","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine and Molecular Imaging, Boston Children\u2019s Hospital, Department of Radiology, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James A.","family":"Inkster","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine and Molecular Imaging, Boston Children\u2019s Hospital, Department of Radiology, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan B.","family":"Packard","sequence":"additional","affiliation":[{"name":"Division of Nuclear Medicine and Molecular Imaging, Boston Children\u2019s Hospital, Department of Radiology, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Zurakowski","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Perioperative and Pain Medicine, Boston Children\u2019s Hospital, Department of Anesthesia, Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Rousselle","sequence":"additional","affiliation":[{"name":"Transplant Research Institute, James D.
