The early adhesion, spreading, proliferation and differentiation of MC3T3-E1 cells on different substrates were investigated in vitro by fluorescent staining, CCK8, alkaline phosphatase activity, mineralization and polymerase chain reaction assays, respectively.Results: Results of ultrasonic and scratch assays showed that the stability of TNTs (especially 125 nm) was significantly improved after being patterned with MP structures. In vitro cell assays further demonstrated that the insertion of MP structure into 125 nm TNT coating, which was denoted as MP125, could effectively improve the early adhesion, spreading and proliferation of surface MC3T3-E1 cells without damaging their osteogenic differentiation.Conclusion: We determined that the MP/TNT patterned samples (especially MP125) have excellent stability and osteogenesis properties, and may have better clinical application prospects.Keywords: titanium, micro-patterned structures, coating stability, osteogenic differentiation  Ding XWang YXu LZhang HDeng ZCai LWu ZYao LWu XLiu JShen XDove Medical Pressarticletitaniummicro-patterned structurescoating stabilityosteogenic differentiationMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 4133-4144 (2019)
