[PMID: 32630066 PMCID: PMC7409016 DOI: 10.3390/jcm9072062] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Revised: 06/23/2020] [Accepted: 06/24/2020] [Indexed: 01/06/2023] Open
Abstract
Osteoarthritis (OA) is the most common degenerative joint disorder worldwide and to date no regenerative treatment has been established in clinical practice. This review evaluates the current literature on the clinical translation of mesenchymal stromal cell (MSC)-based therapy in OA management with a focus on safety, outcomes and procedural specifics. PubMed, Cochrane Library and clinicaltrials.gov were searched for clinical studies using MSCs for OA treatment. 290 articles were initially identified and 42 articles of interest, including a total of 1325 patients, remained for further examination. Most of the included studies used adipose tissue-derived MSCs or bone-marrow-derived MSCs to treat patients suffering from knee OA. MSC-based therapy for knee OA appears to be safe and presumably effective in selected parameters. Yet, a direct comparison between studies was difficult due to a pronounced variance regarding methodology, assessed outcomes and evidence levels. Intensive scientific engagement is needed to identify the most effective source and dosage of MSCs for OA treatment in the future. Consent on outcome measures has to be reached and eventually patient sub-populations need to be identified that will profit most from MSC-based treatment for OA.

Abstract
BACKGROUND The mesenchymal stem cell (MSC)-based tissue engineering approach has been developed to improve the treatment of rotator cuff tears. Hypothesis/Purpose: The purpose was to determine the effect of an injection of adipose-derived MSCs loaded in fibrin glue during arthroscopic rotator cuff repair on clinical outcomes and to evaluate its effect on structural integrity using magnetic resonance imaging (MRI). The hypothesis was that the application of adipose-derived MSCs would improve outcomes after the surgical repair of a rotator cuff tear. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Among 182 patients treated with arthroscopic surgery for a rotator cuff tear, 35 patients treated with arthroscopic rotator cuff repair alone (conventional group) were matched with 35 patients who underwent arthroscopic rotator cuff repair with an injection of adipose-derived MSCs loaded in fibrin glue (injection group) based on sex, age, and lesion size. Outcomes were assessed with respect to the visual analog scale (VAS) for pain, range of motion (ROM) (including forward flexion, external rotation at the side, and internal rotation at the back), and functional measures of the Constant score and University of California, Los Angeles (UCLA) shoulder rating scale. Repaired tendon structural integrity was assessed by using MRI at a minimum of 12 months after surgery, and the mean clinical follow-up was 28.8 ± 4.2 months in the conventional group and 28.3 ± 3.8 months in the injection group. RESULTS The mean VAS score at rest and during motion improved significantly in both groups after surgery. However, there were no significant differences between the groups at the final follow-up ( P = .256 and .776, respectively). Compared with preoperative measurements, forward flexion and external rotation at the side significantly improved at the final follow-up in both groups (all P < .05). However, no significant improvements in internal rotation at the back were observed in either group ( P = .625 and .834 for the conventional and injection groups, respectively). There were also no significant differences between the groups at the final follow-up for any of the 3 ROM positions (all P > .05). The mean Constant score and UCLA score improved significantly in both groups after surgery, but there were no significant differences between the groups at the final follow-up ( P = .634 and .302, respectively). MRI indicated a retear rate of 28.5% in the conventional group and 14.3% in the injection group ( P < .001). CONCLUSION This study revealed that an injection of adipose-derived MSCs loaded in fibrin glue during rotator cuff repair could significantly improve structural outcomes in terms of the retear rate. There were, however, no clinical differences in the 28-month period of follow-up. Although still in the early stages of application, MSC augmentation of surgical rotator cuff repair appears useful for providing an adequate biological environment around the repair site.

Arthroscopy 2016; 32:878-89. [PMID: 26993668 DOI: 10.1016/j.arthro.2016.01.020] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2015] [Revised: 10/30/2015] [Accepted: 01/12/2016] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare the clinical and second-look arthroscopic outcomes in patients undergoing arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy for varus ankle osteoarthritis, with or without adipose-derived mesenchymal stem cell (MSC) injection. METHODS In this retrospective comparative study, 49 patients with varus ankle osteoarthritis underwent second-look arthroscopy after arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy between January 2010 and November 2012; 23 ankles underwent marrow stimulation alone (group 1), and 26 underwent marrow stimulation with MSC injection (group 2). The decision whether to receive the MSC injection, which was free of charge, was solely up to the patients. Second-look arthroscopies were performed at a mean of 12.5 months and 12.4 months postoperatively in group 1 and group 2, respectively. Clinical outcome measures included a visual analog scale (VAS) score for pain and the American Orthopaedic Foot & Ankle Society (AOFAS) score. The radiologic outcome variable was the talar tilt angle. On second-look arthroscopy, cartilage regeneration was evaluated using the International Cartilage Repair Society (ICRS) grade. RESULTS The mean VAS score improved significantly from 7.3 ± 0.9 to 3.9 ± 1.2 in group 1 and from 7.4 ± 0.8 to 3.1 ± 1.5 in group 2 at final follow-up (P < .001 for both groups). The mean AOFAS score also improved significantly from 64.4 ± 4.1 to 79.6 ± 7.7 in group 1 and from 63.5 ± 4.2 to 84.2 ± 7.9 in group 2 at final follow-up (P < .001 for both groups). The VAS and AOFAS scores were significantly better in group 2 than in group 1 (P = .040 and P = .047, respectively). ICRS grades were significantly correlated with clinical outcomes in both groups (all P < .05), and there were significant differences in ICRS grades between the groups (P < .05). The mean talar tilt angle improved significantly after lateral sliding calcaneal osteotomy in both groups and was significantly correlated with clinical outcomes and ICRS grade (all P < .05). CONCLUSIONS In patients with varus ankle osteoarthritis who underwent lateral sliding calcaneal osteotomy, significant improvements in VAS and AOFAS scores, as well as better ICRS grades, were achieved at short-term follow-up after marrow stimulation with additional MSC injection compared with after marrow stimulation alone. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
OBJECTIVE Cartilage regenerative procedures using the cell-based tissue engineering approach involving mesenchymal stem cells (MSCs) have been receiving increased interest because of their potential for altering the progression of osteoarthritis (OA) by repairing cartilage lesions. The aim of this study was to investigate the clinical and magnetic resonance imaging (MRI) outcomes of MSC implantation in OA knees and to determine the association between clinical and MRI outcomes. DESIGN Twenty patients (24 knees) who underwent arthroscopic MSC implantation for cartilage lesions in their OA knees were evaluated at 2 years after surgery. Clinical outcomes were evaluated according to the International Knee Documentation Committee (IKDC) score and the Tegner activity scale, and cartilage repair was assessed according to the MRI Osteoarthritis Knee Score (MOAKS) and Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. RESULTS The clinical outcomes significantly improved (P < 0.001 for both). The cartilage lesion grades (as described in MOAKS [grades for size of cartilage-loss area and percentage of full-thickness cartilage loss]) at follow-up MRI were significantly better than the preoperative values (P < 0.001 for both). The clinical outcomes at final follow-up were significantly correlated with the MOAKS and MOCART score at follow-up MRI (P < 0.05 for all). CONCLUSIONS Considering the encouraging clinical and MRI outcomes obtained and the significant correlations noted between the clinical and MRI outcomes, MSC implantation seems to be useful for repairing cartilage lesions in OA knees. However, a larger sample size and long-term studies are needed to confirm our findings.

Abstract
BACKGROUND Cartilage regenerative procedures have been receiving increased interest because of their potential to alter the progression of osteoarthritis (OA). The application of mesenchymal stem cells (MSCs) has been proposed as a new treatment option for OA based on the ability of these cells to differentiate into chondrocytes. PURPOSE To investigate the clinical and second-look arthroscopic outcomes of MSC implantation and to identify prognostic factors associated with this treatment. STUDY DESIGN Case series; Level of evidence, 4. METHODS This study retrospectively evaluated 37 knees examined using second-look arthroscopic surgery after MSC implantation for cartilage lesions in OA knees. Clinical outcomes were evaluated according to the International Knee Documentation Committee (IKDC) score and Tegner activity scale, and cartilage repair was assessed using International Cartilage Repair Society (ICRS) grading. Statistical analyses were performed to identify various prognostic factors associated with the clinical and second-look arthroscopic outcomes. RESULTS The mean patient age was 57.4 years (range, 48-69 years), the mean follow-up period was 26.5 months (range, 24-34 months), the mean body mass index (BMI) was 26.3 kg/m2 (range, 19.8-31.2 kg/m2), and the mean lesion size was 5.4 ± 2.9 cm2 (range, 2.3-8.9 cm2). The mean IKDC and Tegner activity scale scores were significantly improved from 38.0 ± 7.8 to 61.0 ± 11.0 and from 2.5 ± 0.5 to 3.6 ± 0.7, respectively (P < .001 for both). According to the ICRS overall repair grades at second-look arthroscopic surgery, 2 of the 37 lesions (5%) were grade I (normal), 7 (19%) were grade II (near normal), 20 (54%) were grade III (abnormal), and 8 (22%) were grade IV (severely abnormal). In terms of overall patient satisfaction with the operation, 33 (94%) patients reported good to excellent satisfaction. High BMI (≥27.5 kg/m2) and large lesion size (≥5.4 cm2) were found to be significant predictors of poor clinical and arthroscopic outcomes (P < .05 for both). Other prognostic factors, including patient age, sex, cartilage lesion location, and presence of subchondral cysts, did not significantly influence the outcomes (P > .05). CONCLUSION The outcomes of MSC implantation for cartilage repair in OA knees seem encouraging; high BMI and large lesion size are important factors affecting outcomes. Although still in the early stages of application, MSC implantation for cartilage repair may have great potential for the treatment of OA knees. However, second-look arthroscopic findings revealed that 76% had the repair rated as abnormal or severely abnormal by ICRS standards. The development of an advanced surgical procedure with tissue-engineered scaffolds may be needed to treat patients with large cartilage lesions.

Lipocalin-2-mediated upregulation of various antioxidants and growth factors protects bone marrow-derived mesenchymal stem cells against unfavorable microenvironments. Cell Stress Chaperones 2013; 18:785-800.

Abstract
Despite many advantages of mesenchymal stem cells (MSCs) that make them suitable for cell therapy purposes, their therapeutic application has been limited due to their susceptibility to several stresses (e.g., nutrient-poor environment, oxidative stress, and hypoxic and masses of cytotoxic factors) to which they are exposed during their preparation and following transplantation. Hence, reinforcing MSCs against these stresses is a challenge for both basic and clinician scientists. Recently, much attention has been directed toward equipping MSCs with cytoprotective factors to strengthen them against unfavorable microenvironments. Here, we engineered MSCs with lipocalin 2 (Lcn2), a cytoprotective factor that is naturally induced following exposure of cells to stresses imposed by the microenvironment. Lcn2 overexpression not only did not interfere with the multidifferentiation capacity of the MSCs but also granted many protective properties to them. Lcn2 potentiated MSCs to withstand oxidative, hypoxia, and serum deprivation (SD) conditions via antagonizing their induced cytotoxicity and apoptosis. Adhesion rate of MSCs to coated culture plates was also enhanced by Lcn2 overexpression. In addition, Lcn2 induced antioxidants and upregulated some growth factors in MSCs. Our findings suggested a new strategy for prevention of graft cell death in MSC-based cell therapy.

Abstract
Mesenchymal stem cells (MSCs) have been used for cell therapy in various experimental disease models. However, the regenerative potential of MSCs from different tissue sources and the influence of the tissue niche have not been investigated. In this study, we compared the regenerative potential of dental pulp, bone marrow and adipose tissue-derived CD31(-) side population (SP) cells isolated from an individual porcine source. Pulp CD31(-) SP cells expressed the highest levels of angiogenic/neurotrophic factors and had the highest migration activity. Conditioned medium from pulp CD31(-) SP cells produced potent anti-apoptotic activity and neurite outgrowth, compared to those from bone marrow and adipose CD31(-) SP cells. Transplantation of pulp CD31(-) SP cells in a mouse hindlimb ischemia model produced higher blood flow and capillary density than transplantation of bone marrow and adipose CD31(-) SP cells. Motor function recovery and infarct size reduction were greater with pulp CD31(-) SP cells. Pulp CD31(-) SP cells induced maximal angiogenesis, neurogenesis and pulp regeneration in ectopic transplantation models compared to other tissue sources. These results demonstrate that pulp stem cells have higher angiogenic, neurogenic and regenerative potential and may therefore be superior to bone marrow and adipose stem cells for cell therapy.

Abstract
Advancements in rheumatoid arthritis (RA) treatment protocols and introduction of targeted biological therapies have markedly improved patient outcomes, despite this, up to 50% of patients still fail to achieve a significant clinical response. In veterinary medicine, stem cell therapy in the form of autologous stromal vascular fraction (SVF) is an accepted therapeutic modality for degenerative conditions with 80% improvement and no serious treatment associated adverse events reported. Clinical translation of SVF therapy relies on confirmation of veterinary findings in targeted patient populations. Here we describe the rationale and preclinical data supporting the use of autologous SVF in treatment of RA, as well as provide 1, 3, 6, and 13 month safety outcomes in 13 RA patients treated with this approach.
