Rhazya stricta extract inhibits colony forming ability and wound healing of HepG2 cells in a dose-dependent manner. a Representative images of HepG2 colonies after treatment with increasing concentrations of R. stricta extract. b Percent of area occupied by colonies in treated and non-treated wells (representative of triplicate samples; *P < 0.05, **P < 0.005, ***P < 0.0001) and absorbance of each treated and non-treated wells (representative of 3 biological triplicates, each in triplicate; *P < 0.05, **P < 0.001, ***P < 0.0001). c Representative images and quantification (three regions of three biological triplicates; *P < 0.05, **P < 0.001, ***P < 0.0001) of wound-healing assay results of HepG2 cells treated without or with 20 and 30 μg of R. stricta extract
