Fig. 3 — Monochromatic light differentially modulates the migration and vessel formation of HUVECs co-cultured with MSCs. a, b Photoimages and quantitation data of scratch assay of HUVECs treated with blue/red light, respectively. Photoimages are representative data on 48 h from three independent experiments. Compiled data of migration rates from three independent experiments is shown. Columns, mean; Bars, ± SD. c, d Photoimages and quantitation data of scratch assay of HUVECs co-cultured with MSCs that were treated with blue/red light, respectively. Photoimages are representative data on 48 h from three independent experiments. Compiled data of migration rates from three independent experiments is shown. Columns, mean; Bars, ± SD, *P < 0.05. e Photoimages of vessel formation of HUVECs under monochromatic blue or red light exposure. Results are representative data from three independent experiments. f Tubular lengths and number of junctions assay of HUVECs under light exposure. Results are presented as means ± SD of three independent experiments. g Photoimages of vessel formation of HUVECs co-cultured with MSCs under monochromatic blue or red light exposure. Results are representative data from three independent experiments. h Tubular lengths and number of junctions assay of HUVECs co-cultured with MSCs under monochromatic blue and red light exposure. Results are presented as means ± SD of three independent experiments. ***P < 0.001; ****P < 0.0001
