Med Sci Monit:将负载锶的相转移溶菌酶涂层应用于钛表面以增强成骨和骨髓免疫调节

2019-05-15 不详 网络

通过新型1步相变溶菌酶(PTL)处理制备锶(Sr)-掺杂的钛(Ti)表面,并研究制备的样品对成骨和骨免疫调节的影响。制备了五组钛样品,包括Ti,PTL,PTL @ 10Sr(PTL涂层含10 mg / mL Sr),PTL@20Sr(PTL涂层含20 mg/mL Sr)和PTL @ 50Sr(PTL涂层含50 mg/ mL Sr)组。通过免疫荧光,MTS测定和Transwell系统检查骨髓间充质干

通过新型1步相变溶菌酶(PTL)处理制备锶(Sr)-掺杂的钛(Ti)表面,并研究制备的样品对成骨和骨免疫调节的影响。

制备了五组钛样品,包括Ti,PTL,PTL @ 10Sr(PTL涂层含10 mg / mL Sr),PTL@20Sr(PTL涂层含20 mg/mL Sr)和PTL @ 50Sr(PTL涂层含50 mg/ mL Sr)组。通过免疫荧光,MTS测定和Transwell系统检查骨髓间充质干细胞(BMSC)在不同表面上的初始附着,扩散,增殖和迁移的行为。然后检测BMSCs的成骨分化。探究免疫应答时,通过实时PCR检测由制备的表面诱导的巨噬细胞的极化,并且根据细胞迁移和成骨分化评估BMSC对巨噬细胞条件培养基的响应。最后,使用大鼠股骨植入物模型进行体内研究,以评估材料的成骨诱导和骨免疫调节的可能性。

体外实验表明,PTL涂层可以改善细胞的扩散和粘附,PTL @ Sr层的稳定Sr释放可以促进细胞迁移和成骨。此外,PTL @ Sr表面可调节巨噬细胞的免疫应答,从而增强BMSCs募集和成骨分化。体内评估显示PTL @ 20Sr组中较少的炎性浸润和改善的骨形成。

总之,该研究结果表明,Sr负载的PTL层具有诱导BMSCs成骨分化的更大潜力,同时Sr负载的PTL层可以调节免疫应答,从而促进体外和体内的成骨。
