Background: Several studies have shown the relationship between poorer clinical outcomes of arthroscopic femoroacetabular impingement syndrome surgery and focal chondral defects or global chondromalacia/osteoarthritis. Although recent studies described good outcomes after the conjunctive application of synovial mesenchymal stem cells (MSCs), none demonstrated the application of synovial MSCs for cartilaginous hip injuries. Purpose: To compare the characteristics of MSCs derived from the paralabral synovium and the cotyloid fossa synovium and determine which is the better source. Study Design: Controlled laboratory study. Methods: Synovium was harvested from 2 locations of the hip—paralabral and cotyloid fossa—from 18 donors. The number of cells, colony-forming units, viability, and differentiation capacities of adipose, bone, and cartilage were collected and compared between groups. In addition, real-time polymerase chain reaction was used to assess the differentiation capacity of adipose, bone, and cartilage tissue from both samples. Results: The number of colonies and yield obtained at passage 0 of synovium from the cotyloid fossa was significantly higher than that of the paralabral synovium ( P < .01). In adipogenesis experiments, the frequency of detecting oil red O–positive colonies was significantly higher in the cotyloid fossa than in the paralabral synovium ( P < .05). In osteogenesis experiments, the frequency of von Kossa and alkaline phosphatase positive colonies was higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). In chondrogenic experiments, the chondrogenic pellet culture and the gene expressions of COL2a1 and SOX9 were higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). Conclusion: MSCs from the cotyloid fossa synovium have higher proliferation and differentiation potential than do those from the paralabral synovium and are therefore a better source. Clinical Relevance: Synovial cells from the cotyloid fossa synovium of patients with femoroacetabular impingement syndrome are more robust in vitro, suggesting that MSCs from this source may be strongly considered for stem cell therapy.

Tissue engineering appears promising as an alternative technique for esophageal replacement. Mesenchymal stem cells (MSCs) could be of interest for esophageal regeneration. Evaluation of the ability of an acellular matrix seeded with autologous MSCs to promote tissue remodeling toward an esophageal phenotype after circumferential replacement of the esophagus in a mini pig model. A 3 cm long circumferential replacement of the abdominal esophagus was performed with an MSC-seeded matrix (MSC group, n = 10) versus a matrix alone (control group, n = 10), which has previously been matured into the great omentum. The graft area was covered with an esophageal removable stent. A comparative histological analysis of the graft area after animals were euthanized sequentially is the primary outcome of the study. Histological findings after maturation, overall animal survival, and postoperative morbidity were also compared between groups. At postoperative day 45 (POD 45), a mature squamous epithelium covering the entire surface of the graft area was observed in all the MSC group specimens but in none of the control group before POD 95. Starting at POD 45, desmin positive cells were seen in the graft area in the MSC group but never in the control group. There were no differences between groups in the incidence of surgical complications and postoperative death. In this model, MSCs accelerate the mature re-epitheliazation and early initiation of muscle cell colonization. Further studies will focus on the use of cell tracking tools in order to analyze the becoming of these cells and the mechanisms involved in this tissue regeneration.

Background. In the past decade, mesenchymal stem cells (MSCs) have been widely used for the treatment of osteoarthritis (OA), and noncoding RNAs in exosomes may play a major role. Aim. The present study is aimed at exploring the effect and mechanism of miR-326 in exosomes secreted by bone marrow mesenchymal stem cells (BMSCs) on pyroptosis of cartilage and OA improvement. Methods. Exosomes from BMSCs (BMSC-Exos) were isolated and identified to incubate with OA chondrocytes. Proliferation, migration, specific gene and miR-326 expression, and pyroptosis of chondrocytes were detected. BMSCs or chondrocytes were transfected with miR-326 mimics or inhibitors to investigate the effect of miR-326 in BMSC-Exos on pyroptosis of chondrocytes and the potential mechanism. Finally, a rat OA model was established to verify the effect and mechanism of miR-326 in BMSC-Exos on cartilage of pyroptosis. Results. Incubation with BMSC-Exos could significantly improve the survival rate, migration ability, and chondrocyte-specific genes (COL2A1, SOX9, Agg, and Prg4) and miR-326 expression of OA chondrocytes and significantly inhibit pyroptosis of chondrocytes by downregulation of the levels of inflammatory cytokines, Caspase-1 activity, and pyroptosis-related proteins such as GSDMD, NLRP3, ASC, IL-1β, and IL-18 ( P < 0.01 ). PKH26 labeling confirmed the uptake of BMSC-Exos by chondrocytes. Incubation with exosomes extracted from BMSCs overexpressing miR-326 can significantly repress the pyroptosis of chondrocytes, while knockdown of miR-326 had the opposite effect ( P < 0.01 ). The same result was also demonstrated by direct interference with the expression level of miR-326 in chondrocytes ( P < 0.01 ). In addition, we found that the overexpression of miR-326 significantly inhibited the expression of HDAC3 and NF-κB p65 and significantly promoted the expression of STAT1, acetylated STAT1, and acetylated NF-κB p65 in chondrocytes ( P < 0.01 ). The targeted relationship between miR-326 and HDAC3 was verified by dual-luciferase reporter assay. Animal experiments confirmed the mechanism by which miR-326 delivered by BMSC-Exos inhibits pyroptosis of cartilage by targeting HDAC3 and STAT1/NF-κB p65 signaling pathway. Conclusion. BMSC-Exos can deliver miR-326 to chondrocytes and cartilage and improve OA by targeting HDAC3 and STAT1//NF-κB p65 to inhibit pyroptosis of chondrocytes and cartilage. Our findings provide a new mechanism for BMSC-Exos to treat OA.
