The combined effect of mussel-inspired polydopamine (PDA) surface functionalization and topographical cues on the behavior of skeletal myoblasts is described. On PDA-modified nanofibers, myogenic protein expression and the fusion of myoblasts are increased significantly compared with those on unmodified nanofibers. The multinucleate myotubes on the aligned nanofibers are oriented in a direction parallel to the nanofibers.
本文描述了贻贝启发的聚多巴胺(PDA)表面功能化和形貌线索对成肌细胞行为的协同影响。与未修饰的纳米纤维相比,PDA 修饰的纳米纤维上的成肌蛋白表达和肌细胞融合显著增加。在取向纳米纤维上,多核肌管沿纳米纤维平行方向排列。
