Tube formation assay of HUVECs. HUVECs were co-cultured with transfected HEK293 cells (A–C) and RAW26.4 cells (D–F) for different lengths of time. Then, the capacity of tube formation of HUVECs was observed under a microscope (A,D) and analysed by ImageJ software (B,C,E,F). Tube length (B,E). Total branch length (C,F). ER-INP increases the capacity of tube formation of HUVECs. Data represent the mean ± SD from 3 parallel experiments of representative data from multiple independent experiments (B,C,E,F).
