Figure 11. The effect of rhein on HK-2 cells viability were tested by MTT assay.
(A)Effect of rhein on HK-2 cells proliferation in normal condition by MTT assay.(B) Effect of rhein on LPS-induced HK-2 cells proliferation by MTT assay. Results are expressed as percentage of viable cells when compared with control groups. Data are expressed as mean ± SD. ##p < 0.01 vs. control group, *p < 0.05 and **p < 0.01 vs. LPS alone.
