In vitro photo/gene synergistic treatment to HUVECs. A) Schematic illustration to show the combined photo/gene therapy of HUVECs. B) The fluorescence study of R‐nanoICG/FITC‐S‐siRNA in HUVECs. C) The PAI of HUVECs under treatment of R‐nanoICG/FITC‐S‐siRNA. D) Thin‐section cell TEM images of HUVECs incubated with R‐nanoICG/siRNA. E) Western blot (a) and relative intensity (b) of the expression of survivin and VEGF under R‐nanoICG/S‐siRNA treatment. F) The HUVEC tube formation images (a) and tube length (b) under R‐nanoICG/S‐siRNA treatment and the untreated control group. G) Cell viability of HUVECs under the treatment of different concentrations. H) HUVEC migration images (a) and relative migration rate (b) under GT, PTT, PTT + GT treatment for 0, 12, and 24 h. *p< 0.01, **p< 0.05.
