骨折不愈合和延迟愈合仍然是骨科医生面临的挑战。在本研究中,我们将HMGB 1明胶海绵与MSC片结合,以促进大鼠胫骨骨折手术治疗后的骨愈合。HMGB 1明胶海绵支架支持间充质干细胞(MSC)的扩增,并促进MSC和MSC片的成骨分化。然后使用慢病毒载体在MSC中过表达HMGB 1。结果表明,HMGB 1通过STAT 3途径促进MSCs向成骨细胞分化。siRNA和STAT 3抑制剂均下调STAT 3,进一步证实HMGB 1部分通过STAT 3信号通路诱导MSC的成骨分化。在大鼠胫骨截骨模型中,我们证明了HMGB 1明胶海绵支架增加骨形成的能力。MSC片的加入进一步增强了骨折愈合。这些发现支持使用HMGB 1-加载的明胶海绵支架与MSC片组合来增强手术干预后的骨折愈合。
Fracture nonunion and delayed union continue to pose challenges for orthopedic surgeons. In the present study, we combined HMGB1 gelatin sponges with MSC sheets to promote bone healing after surgical treatment of rat tibial fractures. The HMGB1 gelatin sponge scaffolds supported the expansion of mesenchymal stem cells (MSCs) and promoted the osteogenic differentiation of MSCs and MSC sheets. Lentiviral vectors were then used to overexpress HMGB1 in MSCs. The results indicated that HMGB1 promotes the osteogenic differentiation of MSCs through the STAT3 pathway. Both siRNA and a STAT3 inhibitor downregulated STAT3, further confirming that HMGB1 induces the osteogenic differentiation of MSCs partly via the STAT3 signal pathway. In a rat tibial osteotomy model, we demonstrated the ability of HMGB1 gelatin sponge scaffolds to increase bone formation. The addition of MSC sheets further enhanced fracture healing. These findings support the use of HMGB1-loaded gelatin sponge scaffolds combined with MSC sheets to enhance fracture healing after surgical intervention.
