Figure 1

The proliferative effect of four plants extracts on HGF as indicated by the increase in percentage of HGF population following exposure to the extracts. The rate of cell proliferation of NSSE-treated cell was linear at concentrations below 50 µg/mL but slowed down at higher concentrations above 50 µg/mL. The values plotted were the mean of triplicate tests (). values at were indicated by () and at by ().
