In vitro biological activities such as MC3T3-E1 cell attachment, proliferation and osteogenic activity were studied.Results: With the addition of nHA and nanoparticles, the fiber diameter of PCL/BNPs group, PCL/NNPs group and PCL/nHA/NNPs group was significantly increased. Moreover, the hydrophilic hydroxyl group and amino group presented in nHA and nanoparticles had improved the hydrophilicity of the composite fibers. The composite electrospun containing Chi/NNPs can form a double protective barrier which can effectively prolong the release time of NELL-1 growth factor. In addition, the hydroxyapatite/NELL-1 nanoparticles electrospun fibers can promote attachment, proliferation, differentiation of MC3T3-E1 cells and good cytocompatibility, indicating better ability of inducing osteogenic differentiation.Conclusion: A multi-functional PCL/nHA/NNPs composite fiber with long-term bioactivity and osteoinductivity was successfully prepared by electrospinning. This potential composite could be used as scaffolds in bone tissue engineering application after in vivo studies.Keywords: polycaprolactone, nanoscaffold, MC3T3-E1 cells, osteogenic activitySong HZhang YZhang ZXiong SMa XLi YDove Medical Pressarticlepolycaprolactonenanoscaffoldmc3t3-e1 cellsosteogenic activityMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 4321-4332 (2021)
