Cartilage regenerative medicine has been met with much interest due to their ability to inhibit disease progression of osteoarthritis (OA). The use of adipose-derived stem cells has been suggested as a reliable method for OA treatment because of their potential to differentiate into a variety of cell lines and their potent capability to self-renewal and repair. The aim of this study is to assess adipose-derived stem cells in combination with PRP ability in treating a patient with knee OA. A 53-year- old man with osteoarthritis was selected for this treatment. Human abdominal subcutaneous adipose sample was obtained from a patient with knee OA. Stem cells were obtained from adipose tissue of abdominal origin by digesting lipoaspirate tissue with collagenase. ADSCs cultured in DMEM medium supplemented with 10% FBS. Also, ADSCs expanded and characterized by flow cytometry. These stem cells, along with platelet-rich plasma and calcium chloride, were injected into the right knee. Pre-treatment and post-treatment MRI scans, physical therapy, and pain score data were then analyzed. The MRI data for the patient demonstrated significant positive changes. Probable cartilage regeneration was sensible in the patient. Along with MRI evidence, the measured physical therapy outcomes, subjective pain, and functional status all improved. Autologous adipose-derived stem cell injection, in conjunction with platelet-rich plasma is a promising minimally invasive therapy for osteoarthritis of human knees. The present clinical case report demonstrated that a combination of percutaneous injection of autologous ADSCs and PRPmay be able to regenerate cartilage in human knee OA.

Abstract Background Umbilical cord mesenchymal stem cell (HUCMSC)-based therapies were previously utilised for cartilage regeneration because of the chondrogenic potential of MSCs. However, chondrogenic differentiation of HUCMSCs is limited by the administration of growth factors like TGF-β that may cause cartilage hypertrophy. It has been reported that extracellular vesicles (EVs) could modulate the phenotypic expression of stem cells. However, the role of human chondrogenic-derived EVs (C-EVs) in chondrogenic differentiation of HUCMSCs has not been reported. Results We successfully isolated C-EVs from human multi-finger cartilage and found that C-EVs efficiently promoted the proliferation and chondrogenic differentiation of HUCMSCs, evidenced by highly expressed aggrecan (ACAN), COL2A, and SOX-9. Moreover, the expression of the fibrotic marker COL1A and hypertrophic marker COL10 was significantly lower than that induced by TGF-β. In vivo, C-EVs induced HUCMSCs accelerated the repair of the rabbit model of knee cartilage defect. Furthermore, C-EVs led to an increase in autophagosomes during the process of chondrogenic differentiation, indicating that C-EVs promote cartilage regeneration through the activation of autophagy. Conclusions C-EVs play an essential role in fostering chondrogenic differentiation and proliferation of HUCMSCs, which may be beneficial for articular cartilage repair.

Objective This study aimed to compare microfracture and application of adipose-derived stem cells (ADSCs) by local adherent technique enhanced by platelet-rich plasma (PRP) to provide a new approach for the repair of cartilage defect. Design Full-thickness cylindrical defects were created in the medial femoral condyle in 9 New Zealand White rabbits (5 months old, 4.65 ± 0.20 kg). Two groups of rabbits ( n = 3) were either treated with ADSCs (Group 1) or the microfracture technique (Group 2) following intraarticular injection of PRP 3 times in weekly intervals. Rabbits in control group ( n = 3) remained untreated. The outcome was assessed macroscopically, histologically, and immunohistochemically. Results At the end of week 12, Group 1 showed better defect filling compared with Group 2. Specimens treated with the combination of ADSCs and PRP exhibited significant differences from the other groups in all criteria of International Cartilage Repair Society macroscopic scoring system. Conclusions Intraarticular injection of autologous PRP in combination with transplantation of autologous ADSCs by local adherent technique enhances the quality of cartilage defect repair with better results in comparison with microfracture surgery in a rabbit model.

Tissue engineering cell-based therapy using induced pluripotent stem cells and adipose-derived stem cells (ASCs) may be promising tools for therapeutic applications in tissue engineering because of their abundance, relatively easy harvesting, and high proliferation potential. The purpose of this study was to investigate whether ASCs can promote the auricular cartilage regeneration in the rabbit. In order to assess their differentiation ability, ASCs were injected into the midportion of a surgically created auricular cartilage defect in the rabbit. Control group was injected with normal saline. After 1 month, the resected auricles were examined histopathologically and immunohistochemically. The expression of collagen type II and transforming growth factor-β1 (TGF-β1) were analyzed by quantitative polymerase chain reaction. Histopathology showed islands of new cartilage formation at the site of the surgically induced defect in the ASC group. Furthermore, Masson’s trichrome staining and immunohistochemistry for S-100 showed numerous positive chondroblasts. The expression of collagen type II and TGF-β1 were significantly higher in the ASCs than in the control group. In conclusion, ASCs have regenerative effects on the auricular cartilage defect of the rabbit. These effects would be expected to contribute significantly to the regeneration of damaged cartilage tissue in vivo.
