Cytotoxicity of MSP samples to normal and cancer cell lines. Cytotoxicity of MSP samples to normal and cancer cell lines. (A) Normal cell line 3T3. (B) Cancer cell line SiHa. (C) Cancer cell line Hep G2. From left to right in each column are MTT assays for MSP-0h, MSP-24h, and MSP-72h. In all results, the zero-concentration group with 100% cell viability is set as the control. Six other concentration groups, that is, 25, 50, 100, 200, 400, and 800 μg/ml, are examined and compared with the control group. *P < 0.05 is considered as statistically significant. **P < 0.01, ***P < 0.001. The error bars represent the standard deviation of six independent experiments. Xiaohui Yan et al. Sci.
