摘要:

文题释义:
柚皮苷:是一种天然来源的双氢黄酮类化合物,主要存在于柑橘类水果的果皮和果肉中,具有促进骨髓间充质干细胞增殖及成骨分化的能力,主要用于补肾强骨、治疗骨质疏松及促进骨折愈合。
β-磷酸三钙:具有良好的生物相容性、降解性及骨传导性,易被新的骨基质取代,通过溶解和吸收过程促进成骨,是一种良好的骨修复材料。

背景:柚皮苷具有促进骨髓间充质干细胞增殖及成骨分化的能力,可用于治疗骨质疏松及促进骨折愈合,然而其生物利用率低,临床应用受限。
目的:制备负载柚皮苷的壳聚糖/β-磷酸三钙支架,表征其生物学性能。
方法:采用冷冻干燥和化学交联法制备壳聚糖/β-磷酸三钙支架,将壳聚糖/β-磷酸三钙支架浸泡于含柚皮苷的无水乙醇溶液中3 h,真空冷冻干燥后得到壳聚糖/β-磷酸三钙/柚皮苷支架,表征支架的孔径、孔隙率、溶胀率、降解率、机械性能及柚皮苷的体外释放能力。将大鼠骨髓间充质干细胞分别接种于壳聚糖/β-磷酸三钙支架与壳聚糖/β-磷酸三钙/柚皮苷支架表面,检测细胞增殖、黏附、活性及成骨诱导分化后的碱性磷酸酶活性。
结果与结论:①扫描电镜下可见壳聚糖/β-磷酸三钙/柚皮苷支架具有多孔网状结构,平均孔径为(106.82±25.22) μm,孔隙率为(76.26±4.81)%,24 h溶胀率为(796.17±31.76)%,4周时体外降解率为7.71%,体外可释放柚皮苷长达9 d,壳聚糖/β-磷酸三钙/柚皮苷支架的平均孔径、孔隙率、24 h溶胀率、4周时体外降解率、压缩强度、压缩模量与壳聚糖/β-磷酸三钙支架比较差异均无显著性意义(P > 0.05);②大鼠骨髓间充质干细胞在两种支架表面黏附良好,并具有良好的活性,相较于壳聚糖/β-磷酸三钙支架,壳聚糖/β-磷酸三钙/柚皮苷支架可促进大鼠骨髓间充质干细胞的增殖(P < 0.05),提高成骨诱导分化后的骨髓间充质干细胞碱性磷酸酶活性(P < 0.05);③结果表明,壳聚糖/β-磷酸三钙/柚皮苷支架具有良好的物理性能,可促进骨髓间充质干细胞的增殖及成骨分化。

Abstract: BACKGROUND: Naringin has been shown to promote the proliferation and osteogenic differentiation of bone marrow derived mesenchymal stem cells, making it a potential candidate for treating osteoporosis andenhancing fracture healing. However, its clinical application is limited by its low bioavailability.
OBJECTIVE: To prepare chitosan/β-tricalcium phosphate scaffolds loaded with naringin and characterize their biological properties.
METHODS: Chitosan/β-tricalcium phosphate scaffolds were prepared by freeze-drying and chemical crosslinking. The chitosan/β-tricalcium phosphate scaffolds were immersed in anhydrous ethanol solution containing naringin for 3 hours. After vacuum cold drying, chitosan/β-tricalcium phosphate/naringin scaffolds were obtained. The pore size, porosity, swelling rate, degradation rate, mechanical properties, and in vitro release capacity of naringin of the scaffolds were characterized. Rat bone marrow mesenchymal stem cells were inoculated on the surface of chitosan/β-tricalcium phosphate scaffolds and chitosan/β-tricalcium phosphate/naringin scaffolds, respectively, and cell proliferation, adhesion, activity and alkaline phosphatase activity after osteogenic differentiation were detected.
RESULTS AND CONCLUSION: (1) The results of scanning electron microscopy showed that the naringin-chitosan/β-tricalcium phosphate composite scaffold had a porous mesh structure. The average pore diameter was (106.82±25.22) μm; the porosity was (76.26±4.81)%; 24-hour swelling rate was (796.17±31.76)%; in vitro degradation rate of 7.71% at 4 weeks, and naringin could be slowly released in vitro for 9 days. There was no significant difference in the average pore size, porosity, 24-hour swelling rate, in vitro degradation rate, compression strength and compression modulus at 4 weeks between the chitosan/β-tricalcium phosphate scaffold and the chitosan/β-tricalcium phosphate scaffold (P > 0.05). (2) Rat bone marrow mesenchymal stem cells adhered well to the surfaces of the two scaffolds and had good activity. Compared with the chitosan/β-tricalcium phosphate scaffold, the chitosan/β-tricalcium phosphate/naringin scaffold promoted the proliferation of rat bone marrow mesenchymal stem cells (P < 0.05), and increased the alkaline phosphatase activity of bone marrow mesenchymal stem cells after osteogenic differentiation (P < 0.05). (3) The results show that the chitosan/β-tricalcium phosphate/naringin scaffolds exhibit favorable physical properties and can effectively promote the adhesion, proliferation, and osteogenic differentiation of bone marrow-derived mesenchymal stem cells.
