Effects of EGCG as well as H₂O₂ on NPCs viability. (A) Chemical structure of EGCG. (B) Findings from CCK-8 indicating NPCs viability after treatment with various concentrations of EGCG and (C) H₂O₂ for 24 h. (D) Cell viabilities of NPCs after 300 μM H₂O₂ treatment at various times (0, 6, 12, as well as 24 h). (E) CCK-8 findings indicating NPCs viability after treatment with 300 µM H₂O₂ and different concentrations of EGCG for 24 h. Data are shown as mean ± SD (n = 3). ^* p < 0.05, ^** p < 0.01.
