From: Improving Magnetofection of Magnetic Polyethylenimine Nanoparticles into MG-63 Osteoblasts Using a Novel Uniform Magnetic Field

Fig. 5

Comparison of cytotoxicity effects of the uniform magnetic field and non-uniform magnetic field, PEI-SPIO-NPs/pDNA complexes, PolyMag-200/pDNA complexes and PEI-NPs/pDNA complexes, and different nanoparticles with pDNA and without pDNA on MG-63 osteoblasts. Cytotoxicity is detected by the CCK-8 test kit, the absorbance was measured at a wavelength of 450 nm, which reflects the cell viability, and the high viability is indicative of the low cytotoxicity. The results are expressed as the mean ± SD (n = 5, one-way ANOVA, *P < 0.05, **P < 0.01). a The cytotoxicity effects of PEI-SPIO-NPs/pDNA complexes, PolyMag-200/pDNA complexes and PEI-NPs/pDNA complexes on MG-63 osteoblasts. b The cytotoxicity effects of the uniform magnetic field and non-uniform magnetic field on MG-63 osteoblasts and c the cytotoxicity effects of different nanoparticles with pDNA and without pDNA
