NDI1 can resist the morphological changes and the decrease of cell survival in MPP⁺-induced PD cell culture model. A: Cell morphology was observed with microscope (scale bar: 50 μm). B: Cell viability was determined with trypan blue staining. C: Statistical analysis of cell viability. ns: no significant difference, *: P < 0.05, **: P < 0.01
