Figure 2.

In vitro cell proliferation assay of doxorubicin treated (a) and MMTC treated (b) normal lymphocytes, KG-1A and K562 cell lines. Cells were treated with doxorubicin and MMTC for 24 h at 37°C. Cell viability was measured by the MTT method as described in Section 2. Values are expressed as mean ± SEM of three experiments; ∗ and # indicate significant difference (P < 0.05) compared to the control group.
