However, bone substitutes have only osteoconductive properties and lack osteoinductive potential. Therefore, this phase I study evaluated the potential additive effect on bone regeneration by the addition of freshly isolated, autologous but heterologous stromal vascular fraction (SVF), which is highly enriched with adipose stromal\/stem cells when compared with native adipose tissue. From 10 patients, SVF was procured using automatic processing, seeded on either \u03b2-tricalcium phosphate (n = 5) or biphasic calcium phosphate carriers (n = 5), and used for MSFE in a one-step surgical procedure. Primary objectives were feasibility and safety. The secondary objective was efficacy, evaluated by using biopsies of the augmented area taken 6 months postoperatively, concomitant with dental implant placement. Biopsies were assessed for bone, graft, and osteoid volumes. No adverse effects were reported during the procedure or follow-up (\u22653 years). Bone and osteoid percentages were higher in study biopsies (SVF supplemented) than in control biopsies (ceramic only on contralateral side), in particular in \u03b2-tricalcium phosphate-treated patients. Paired analysis on the six bilaterally treated patients revealed markedly higher bone and osteoid volumes using microcomputed tomography or histomorphometric evaluations, demonstrating an additive effect of SVF supplementation, independent of the bone substitute. This study demonstrated for the first time the feasibility, safety, and potential efficacy of SVF seeded on bone substitutes for MSFE, providing the first step toward a novel treatment concept that might offer broad potential for SVF-based regenerative medicine applications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Significance<\/jats:title><jats:p>This is the first-in-human study using freshly isolated, autologous adipose stem cell preparations (the stromal vascular fraction [SVF] of adipose tissue) applied in a one-step surgical procedure with calcium phosphate ceramics (CaP) to increase maxillary bone height for dental implantations. All 10 patients received CaP plus SVF on one side, whereas bilaterally treated patients (6 of 10) received CaP only on the opposite side. This allowed intrapatient evaluation of the potential added value of SVF supplementation, assessed in biopsies obtained after 6 months. Feasibility, safety, and potential efficacy of SVF for bone regeneration were demonstrated, showing high potential for this novel concept.<\/jats:p><\/jats:sec>","DOI":"10.5966\/sctm.2015-0369","type":"journal-article","created":{"date-parts":[[2016,7,8]],"date-time":"2016-07-08T03:08:59Z","timestamp":1467947339000},"page":"1362-1374","source":"Crossref","is-referenced-by-count":109,"title":["Bone Regeneration Using the Freshly Isolated Autologous Stromal Vascular Fraction of Adipose Tissue in Combination With Calcium Phosphate Ceramics"],"prefix":"10.1093","volume":"5","author":[{"given":"Henk-Jan","family":"Prins","sequence":"first","affiliation":[{"name":"Department of Oral Cell Biology, Academic Centre for Dentistry Amsterdam (ACTA), MOVE Research Institute Amsterdam, VU University Amsterdam, Amsterdam, The Netherlands"},{"name":"Department of Oral and Maxillofacial Surgery, MOVE Research Institute Amsterdam, VU University Medical Center\/ACTA, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Engelbert A.J.M.","family":"Schulten","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, MOVE Research Institute Amsterdam, VU University Medical Center\/ACTA, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christiaan M.","family":"ten Bruggenkate","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, MOVE Research Institute Amsterdam, VU University Medical Center\/ACTA, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenneke","family":"Klein-Nulend","sequence":"additional","affiliation":[{"name":"Department of Oral Cell Biology, Academic Centre for Dentistry Amsterdam (ACTA), MOVE Research Institute Amsterdam, VU University Amsterdam, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco N.","family":"Helder","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, MOVE Research Institute Amsterdam, VU University Medical Center, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2016,7,7]]},"reference":[{"key":"2021122705113284400_R1","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1016\/j.ijom.2011.10.001","article-title":"Maxillary sinus lift with solely autogenous bone compared to a combination of autogenous bone and growth factors or (solely) bone substitutes.
