Cell viability assay of EC, astrocytes and pericytes cells incubated with GNR-PEG-Ang2/D1 at different concentrations for 24 h. Live control corresponds to the cells with only their culture medium and the death control corresponds to cells incubated with staurosporine 1 µM (N = 3) **** p < 0.0001, ***p < 0.001 and **p < 0.01
