Polydactyly-derived allogeneic chondrocyte cell-sheet transplantation with high tibial osteotomy as regenerative therapy for knee osteoarthritis.
Allogeneic cell therapies are not fully effective in treating osteoarthritis of the knee (OAK). We recently reported that transplantation of autologous chondrocyte cell-sheets along with open-wedge high tibial osteotomy promoted hyaline cartilage repair in humans. Here we describe our regenerative therapy for OAK using polydactyly-derived allogeneic chondrocyte cell-sheets (PD sheets) and temperature-responsive culture inserts. Ten patients with OAK and cartilage defects categorized arthroscopically as Outerbridge grade III or IV received the therapy. Cartilage viscoelasticity and thickness were assessed before and after transplantation. Arthroscopic biopsies obtained 12 months after transplantation were analyzed histologically. Gene expression was analyzed to evaluate the PD sheets. In this small initial longitudinal series, PD sheet transplantation was effective in treating OAK, as indicated by changes in cartilage properties. Gene marker sets in PD sheets may predict outcomes after therapy and provide markers for the selection of donor cells. This combined surgery may be an ideal regenerative therapy with disease-modifying effects in OAK patients.
期刊介绍：
Regenerative Medicine, an innovative online-only journal, aims to advance research in the field of repairing and regenerating damaged tissues and organs within the human body. As a part of the prestigious Nature Partner Journals series and in partnership with ARMI, this high-quality, open access journal serves as a platform for scientists to explore effective therapies that harness the body's natural regenerative capabilities. With a focus on understanding the fundamental mechanisms of tissue damage and regeneration, npj Regenerative Medicine actively encourages studies that bridge the gap between basic research and clinical tissue repair strategies.
