Triterpenoids from the Leaves of Centella asiatica Inhibit Ionizing Radiation-Induced Migration and Invasion of Human Lung Cancer Cells

Figure 2

Effects of compounds 1–3 on IR-induced A549 cell migration: (a) wound-healing assay to examine the effects of the indicated compounds (50 μM) on the IR-induced migration of A549 cells; (b) quantification of the wound width. The relative wound width was calculated as the ratio of the remaining wound width at a given time point to the original wound width created at 0 h Data represent the mean ± SD (n = 3), versus the control (10 Gy IR).
