摘要:

目的 探究柚皮素(Nar)对脂多糖(LPS)刺激下的人牙周膜干细胞(hPDLSCs)抗炎、成血管和成骨能力的影响及其机制。 方法 采用细胞计数试剂盒(CCK-8)、划痕试验和Transwell实验研究hPDLSCs的增殖和迁移能力。采用碱性磷酸酶(ALP)染色、茜素红染色、管腔形成实验、酶联免疫吸附实验(ELISA)、实时荧光定量逆转录聚合酶链反应(qRT-PCR)和蛋白印迹实验(Western blot)检测hPDLSCs抗炎、成血管和成骨分化能力。 结果 10 μmol/L Nar可减轻10 μg/mL LPS刺激的hPDLSCs炎症反应,促进其增殖、迁移和成血管分化,0.1 μmol/L Nar可有效恢复10 μg/mL LPS刺激的hPDLSCs成骨能力。加入CXCR4抑制剂AMD3100后,Nar促进抗炎和成骨分化的作用降低,炎性hPDLSCs成血管分化升高。 结论 Nar促进了hPDLSCs抗炎、成血管和成骨分化,该作用与基质细胞衍生因子1/趋化因子受体4信号轴有关。

Abstract:

Objective This study aimed to investigate how naringenin (Nar) affected the anti-inflammatory, vascula-rization, and osteogenesis differentiation of human periodontal ligament stem cells (hPDLSCs) stimulated by lipopolysaccharide (LPS) and to preliminarily explore the underlying mechanism. Methods Cell-counting kit-8 (CCK8), cell scratch test, and Transwell assay were used to investigate the proliferation and migratory capabilities of hPDLSCs. Alkaline phosphatase (ALP) staining, alizarin red staining, lumen-formation assay, enzyme-linked immunosorbent assay, quantitative timed polymerase chain reaction, and Western blot were used to measure the expression of osteopontin (OPN), Runt-related transcription factor 2 (RUNX2), vascular endothlial growth factor (VEGF), basic fibroblast growth factor (bFGF), von Willebrand factor (vWF), tumor necrosis factor-α (TNF-α), and interleukin (IL)-6. Results We observed that 10 μmol/L Nar could attenuate the inflammatory response of hPDLSCs stimulated by 10 μg/mL LPS and promoted their proliferation, migration, and vascularization differentiation. Furthermore, 0.1 μmol/L Nar could effectively restore the osteogenic differentiation of inflammatory hPDLSCs. The effects of Nar’s anti-inflammatory and promotion of osteogenic differentiation significantly decreased and inflammatory vascularization differentiation increased after adding AMD3100 (a specific CXCR4 inhibitor). Conclusion Nar demonstrated the ability to promote the anti-inflammatory, vascularization, and osteogenic effects of hPDLSCs stimulated by LPS, and the ability was associated with the stromal cell-derived factor/C-X-C motif chemokine receptor 4 signaling axis.
