Objective: The significant factor contributing to the distant invasion of cancer cells is theability of tumors to produce large numbers of new blood vessels, known as angiogenesis.Many natural products inhibit angiogenesis. Herein, ethanol extract of Salvia officinalis(SO) has been analyzed for its anti-angiogenic, anti-proliferation and anti-migration activities.Materials and Methods: The anti-angiogenic effect of the SO extract was evaluated onchicken chorioallantoic membrane (CAM) neovascularisation model, microscopically. Theinhibitory effect of the extract on human umbilical vein endothelial cells (HUVECs) migrationwas tested on the wound-healing model with an inverted microscope. In addition,SO extract was screened for its possible anti-proliferative effects by separately countingHUVECs, Wehi and K562 cells with cell counter against their control wells.Results: So extract exhibited a significant inhibitory activity in CAM assay in a dose dependentmanner. CAM angiogenesis was gradually prevented to from at 100 μg/ml of SOextract, but completely inhibited to form at 200 μg/ml. After human umbilical vein endothelialcells (HUVECs) were suppressed by dose-dependent SO extract, their migrations weredetected by wound healing model, yet they were unable to show a dose response effecton proliferation of the different cells (50-200 μg/ml). As observing in this study, SOextractcould inhibit proliferation of the different cells at the concentrations above 200 μg/ml withouttoxic effect on the cells in doses ranged from 0-500 μg/ml.Conclusion: These findings indicated that SO extract might be a promising candidate foranti-angiogenic treatment.
