Osteoarthritis (OA) is a chronic degenerative joint disease and is considered to be the fourth leading cause of disability and the second cause of inability to work in men. Recently, adipose-derived mesenchymal stem cells (AD-MSCs) came into focus for regenerative medicine as a promising tool for the treatment of OA. The administration of stem cells into impaired joints results in pain relief and improves quality of life, accompanied by restoration of hyaline articular cartilage. In the present study, nine patients (including two patients with bilateral symptoms) diagnosed with osteoarthritis (International Knee Documentation grade B in 5 and grade D in six knees) were treated using a single injection of AD-MSCs at a concentration of 0.5-1.0 × 107 cells and were followed up for 18 months. During follow-up, all the cases were evaluated clinically by Knee Society score (KSS), Hospital for Special Surgery knee score (HSS-KS), Tegner-Lysholm (T-L) score and visual analogue scale (VAS) o...

The current study explored the efficacy of an intra-articular (IA) injection of allogeneic adipose tissue-derived stem cells (ADSCs) combined with xanthan gum (XG) in a rat osteoarthritis (OA) model. We confirmed that XG significantly inproved proliferation of ADSCs in a dose dependent manner in vitro. The rat OA model was induced by an anterior cruciate ligament transection (ACLT), and at 4 weeks after surgery, rats were divided into four groups: the XG-ADSCs group, the ADSCs group, the XG group and the phosphate-buffered saline (PBS) group. A single dose of 1 × 10(6) allogeneic ADSCs suspended in 1% XG, ADSCs suspended in PBS, 1% XG alone or PBS alone was injected into the OA joint of rats in the respective treatment groups. Rats were sacrificed at 8 weeks after surgery. Treatment outcomes were evaluated by weight-bearing control of the hind limbs, gross morphological analysis, histological analysis and specific staining of articular cartilage, and measurement of inflammatory fact...

Osteoarthritis (OA) of the knee is a debilitating condition that can severely limit an individual’s mobility and quality of life. This study was designed to evaluate the efficacy of bone marrow-derived mesenchymal stem cell (BM-MSC) treatment in cartilage repair using a rat model of monoiodoacetate- (MIA-) induced knee OA. OA was induced in the knee joint of rats by an intracapsular injection of MIA (2 mg/50 μL) on day zero. The rats were divided into three groups ( n = 6 ): a normal control group, an osteoarthritic control group, and an osteoarthritic group receiving a single intra-articular injection of BM-MSCs ( 5 × 10 6 cells/rat). The knee diameter was recorded once per week. By the end of the performed experiment, X-ray imaging and enzyme-linked immunosorbent assay analysis of serum inflammatory cytokines interleukin-1beta (IL-β), IL-6, and tumor necrosis factor-α (TNF-α) and anti-inflammatory cytokines interleukin-10 and transforming growth factor-beta (TGF-β) were carried ou...

Journal of Orthopaedic Science and Research, 2022
Background: Adipose tissue has achieved a great relevance as possible fount of mesenchymal stem cells for the healing of different articular pathologies including Knee Osteoarthritis (KOA). Stem cells derived from the Adipose Tissue (ADSCs) have a possibility to differentiate into chondrocyte, can reduce the immune response and can stimulate a local tissue repair, improving also the intra-articular Methods and Findings: Intra-articular injections of ADSCs with other conservative or surgical treatments can lead to an improving of all clinical and functional postoperative outcomes evaluated in middle-aged patients with KOA or chondral lesions. Moreover, some scores based on Magnetic Resonance Imaging (MRI) demonstrated an incremented quality of repaired cartilage in comparison with the pre-treatment. We observed no serious advent events. Conclusion: The use of ADSCs appeared to be out of danger, effective and it can be supposed an alternative procedure for the healing of chondral lesions and degenerative OA suitable for middle-aged athlete but no specific studies have been focus on this population and no long term follow-up data are available.

Application of mesenchymal stem/stromal cells (MSCs) in treating different disorders, in particular osteo-articular diseases, is currently under investigation. We have already documented the safety of administrating human adipose tissue-derived stromal MSCs (hASCs) in immunodeficient mice. In the present study, we investigated whether the persistence of MSC is affected by the degree of inflammation and related to the therapeutic effect in two inflammatory models of arthritis. We used C57BL/6 or DBA/1 mice to develop collagenase-induced osteoarthritis (CIOA) or collagen-induced arthritis (CIA), respectively. Normal and diseased mice were administered 2.5×105 hASCs in the knee joints (IA) or 106 in the tail vein (IV). For CIA, clinical scores were monitored during the time course of the disease while for CIOA, OA scores were assessed by histology at euthanasia. Thirteen tissues were recovered at different time points and processed for real-time PCR and Alu sequence detection. Immunolo...
Objective: Synovitis is evident in a substantial subpopulation of patients with osteoarthritis (OA) and is associated with development of pathophysiology. Recently we have shown that adipose-derived stem cells (ASC) inhibit joint destruction in collagenase-induced experimental OA (CIOA). In the current study we explored the role of synovitis and alarmins S100A8/A9 in the immunomodulatory capacity of ASCs in experimental OA. Method: CIOA, characterized by synovitis, and surgical DMM (destabilization of medial meniscus) OA were treated locally with ASCs. Synovial activation, cartilage damage and osteophyte size were measured on histological sections. Cytokines in synovial washouts and serum were determined using Luminex or enzyme-linked immunosorbent assay (S100A8/A9), mRNA levels with reverse-transcriptase (RT)-qPCR. Results: Local administration of ASCs at various time-points (days 7 or 14) after DMM induction had no effect on OA pathology. At day 7 of CIOA, already 6 h after ASC in...
Meta-Analysis of Adipose Tissue Derived Cell-Based Therapy for the Treatment of Knee Osteoarthritis
Cells, 2021
Osteoarthritis (OA) is a degenerative disorder associated with cartilage loss and is a leading cause of disability around the world. In old age, the capacity of cartilage to regenerate is diminished. With an aging population, the burden of OA is set to rise. Currently, there is no definitive treatment for OA. However, cell-based therapies derived from adipose tissue are promising. A PRISMA systematic review was conducted employing four databases (MEDLINE, EMBASE, Cochrane, Web of Science) to identify all clinical studies that utilized adipose tissue derived mesenchymal stem cells (AMSCs) or stromal vascular fraction (SVF) for the treatment of knee OA. Eighteen studies were included, which met the inclusion criteria. Meta-analyses were conducted on fourteen of these studies, which all documented WOMAC scores after the administration of AMSCs. Pooled analysis revealed that cell-based treatments definitively improve WOMAC scores, post treatment. These improvements increased with time. ...

Purpose The purpose of this study was to report the clinical and functional results of a series of patients with early knee osteoarthritis (KOA) treated with the intra-articular injection of autologous adipose-derived stem cells (aASCs) plus arthroscopic debridement. The hypothesis was that protocol would significantly improve the clinical and functional outcomes in patients with early KOA. Methods Fifty-two patients with early KOA, who received arthroscopic debridement followed by percutaneous injection of aASCs, were enrolled into the study and retrospectively analyzed with an average follow-up of 15.3 (range, 6 to 24) months. Patients were assessed through the IKS knee and function scores and VAS pain scale. Results The mean IKS knee score improved from 37.4 (range, 14 to 79) points pre-operatively to 62.6 (range, 27 to 95) points at the latest follow-up (p < < 0.01). The mean IKS function score improved from 57.2 (range, 25 to 100) points pre-operatively to 83.0 (range, 35 to 100) points at the latest follow-up (p < < 0.01). The mean VAS score decreased from 8.5 (range, 3 to 10) preoperatively to 5.1 (range, 0 to 8) at the latest follow-up (p < < 0.01). Additionally, patients with a pre-operative VAS score greater than 8 were found to show greater clinical and functional benefits compared with patients with VAS score lower than 8. Conclusions The knee injection of aASCs associated to arthroscopic debridement increased significantly the clinical and functional scores in patients with early KOA at a mid-term follow-up, especially those with higher pre-operative VAS scores.
Are Stem Cells Derived from Synovium and Fat Pad Able to Treat Induced Knee Osteoarthritis in Rats?
International Journal of Rheumatology
Background. Osteoarthritis (OA) is a chronic disease and a significant cause of joint pain, tenderness, and limitation of motion. At present, no specific treatment is available, and mesenchymal stem cells (MSCs) have shown promising potentials in this regard. Herein, we aimed to evaluate the repairing potentials of stem cells derived from the synovium and fat pad in the treatment of OA. Methods. Twenty-eight male rats (220±20 g, aged 10-12 weeks), were randomly divided into four groups (n=7): C1: nontreated group, C2: Hyalgan-treated group, E1: adipose tissue-derived stem cell-treated group, and E2: synovial membrane-based stem cell-treated group. Collagenase type II was injected into the left knee; after eight weeks, OA was developed. Then, stem cells were injected, and rats were followed for three months. Afterward, specimens and radiological images were investigated. p value ≤ 0.05 was set as statistically significant. Results. Compared to the C1 group, the E1 and E2 groups showe...
