Cytotoxicity of MitoQ
(A) Chemical structure of MitoQ.
(B) The CCK-8 results of MitoQ (0.125, 0.25, 0.5, 1, and 2 μM). IC50 = 1.094 μM.
(C–E) Toluidine blue staining on chondrocytes exposed to IL-1β and MitoQ (scale bar: 400 μm) (D and E) EdU staining on chondrocytes (scale bar: 200 μm). Data are represented as mean ± SD, ns = not significant, (n = 3).
