The transfer of mitochondria to cell therapy products before their administration can enhance therapeutic outcomes. However, the low efficiency of previously reported methods limits their clinical application. Here, we developed a droplet microfluidics\u2013based mitochondrial transfer technique that can achieve high-efficiency and high-throughput quantitative mitochondrial transfer to single cells. Because mitochondria are essential for muscles, myoblast cells and a muscle injury model were used as a proof-of-concept model to evaluate the proposed technique. In vitro and in vivo experiments demonstrated that C2C12 cells with 31 transferred mitochondria had significant improvements in cellular functions compared to those with 0, 8, and 14 transferred mitochondria and also had better therapeutic effects on muscle regeneration. The proposed technique can considerably promote the clinical application of mitochondrial transfer, with optimized cell function improvements, for the cell therapy of mitochondria-related diseases.<\/jats:p>","DOI":"10.1126\/sciadv.abp9245","type":"journal-article","created":{"date-parts":[[2022,8,17]],"date-time":"2022-08-17T13:57:37Z","timestamp":1660744657000},"source":"Crossref","is-referenced-by-count":61,"title":["High-efficiency quantitative control of mitochondrial transfer based on droplet microfluidics and its application on muscle regeneration"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9932-5483","authenticated-orcid":true,"given":"Jiayu","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, City University of Hong Kong, Hong Kong, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3329-6090","authenticated-orcid":true,"given":"Hiu Tung Jessica","family":"Lo","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."},{"name":"Li Ka Shing Institute of Health Sciences, The Chinese University of Hong Kong, Shatin, Hong Kong SAR, China."},{"name":"Stem Cells and Regenerative Medicine Laboratory, Lui Che Woo Institute of Innovative Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4733-672X","authenticated-orcid":true,"given":"Lei","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, City University of Hong Kong, Hong Kong, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5272-0067","authenticated-orcid":true,"given":"Tsz Lam","family":"Yiu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."},{"name":"Li Ka Shing Institute of Health Sciences, The Chinese University of Hong Kong, Shatin, Hong Kong SAR, China."},{"name":"Stem Cells and Regenerative Medicine Laboratory, Lui Che Woo Institute of Innovative Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0646-5231","authenticated-orcid":true,"given":"Adnan","family":"Shakoor","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, City University of Hong Kong, Hong Kong, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3981-2239","authenticated-orcid":true,"given":"Gang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."},{"name":"Li Ka Shing Institute of Health Sciences, The Chinese University of Hong Kong, Shatin, Hong Kong SAR, China."},{"name":"Stem Cells and Regenerative Medicine Laboratory, Lui Che Woo Institute of Innovative Medicine, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin, Hong Kong SAR, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0486-360X","authenticated-orcid":true,"given":"Wayne Y.
