HUVEC proliferation and survival on surfaces presenting covalently immobilized VR-BP. HUVECs were seeded onto SAM arrays presenting (A) 5% or (B) 0.5% GRGDSP with varied densities of VR-BP including 1%, 0.1%, 0.01% and 0% and allowed to attach for 3 hours. After attachment, HUVECs were stimulated with VEGF concentrations of 0 ng/mL, 10ng/mL, 100 ng/mL. As indicated, 10 μM SU5416 was included during cell seeding and washed out before stimulation with VEGF. Normalized cell number after 72 hours of culture in (C) 5% or (D) 0.5% GRGDSP. (Error bars indicate standard error of the mean. Asterisk indicate significance decrease compared to 0% VR-BP at p < 0.05)
