Combination of compounds promotes cell migration and tube formation in vitro. A Representative images of cell horizontal migration following treatment with Atr I, Atr III, and Pae, both individually and in combination. B Bar graph depicting the quantification of cell horizontal migration (the ratio of migrated area to scratch area). C Representative images of cell transwell migration assays treated with the combination of Atr III and Pae. D Bar graph shows the quantification of cell number. E Representative images of cell tube formation results. F Bar graph depicting the quantification of tube number. Data are expressed as mean ± SD. n = 4 per group. *p < 0.05, **p < 0.01 vs. Control group
