Immunolabeling of p-VEGFR2 expression in BCAECs cultured on the experimental surfaces. a BCAECs on the NT surface at day 1 of culture; b Ti6Al4V surface with endothelial cells at day 1; c NTs with BCAECs at day 3 of cell growth; d BCAECs on Ti6Al4V flat surface at day 3 of incubation; e NT surface with BCAECs at day 8 of cell seeding; f Ti6Al4V control surface at day 8 of cultivation; and g Graph of the cellular fluorescence intensity used to measure the expression of p-VEGFR2. Values are mean ± SD, N = 5. *Denotes differences between NT surface at day 3 versus day 1 of culture on NTs and Ti6Al4V alloy. **Illustrates significant changes for NTs at day 3 compared to Ti6Al4V at day 3 and for the NTs. ***Represents statistical differences between NTs and Ti6Al4V at day 8 of incubation. $Denotes important divergences after analyzing NTs at day 1 and NTs at day 3 and 8. # Remarkable contrast between Ti6Al4V at day 8 and NTs at day 3
