Fig. 4. Comparison of proliferative effects of BV and PBV on HDF cells. For starting the experiment, the culture medium of HDF cell was changed to serum free medium and then the cells were treated with either BV or PBV for 72 hr. Cell proliferation was measured using MTT assay. The data shown are the means ± SD of three experiments. Significant difference from control group, *p < 0.05.
