Citicoline increases the MMP of HEI-OC-1 cells after neomycin exposure. (A) The three groups of HEI-OC-1 cells were labeled using the TMRE staining kit. (B) Flow cytometry data confirmed the results in (A). (C) Quantification of the flow cytometry results in (B). The TMRE intensity was significantly decreased after neomycin exposure compared to the undamaged controls. In addition, the TMRE intensity was significantly increased in the citicoline treatment group compared to the neomycin-only group. Data are shown as mean ± SD. *p < 0.05, **p < 0.01, ***p < 0.001. Scale bars = 20 μm.
