Sesamin suppressed SP cells proliferation and enhanced the chemotherapeutic effect of cisplatin (Cis). Sesamin effectively inhibited the viability of SP cells in a dose- and time-dependent manner (A and B). Sesamin manifested its chemo-sensitization effects on SP cells from both SGC-996 and GBC-SD (C). *p < 0.05 vs. control group. #
