Effect of DPSC-CM on carcinoma cell lines. A Cell viability of carcinoma cells in the vehicle (DMEM), N-CM, or H-CM groups after 48 h of incubation. HeLa, n = 5 in each group; SAS, n = 6 in each group. B, C Tumor volume and tumor weight (day 21) in a subcutaneous tumor model (C3H/HeNCrl mice) that mimics head and neck squamous cell carcinoma (SCC). n = 3 in each group. A–C Data are presented as mean ± SEM. *P < 0.05, **P < 0.01
