Shear stress-mediated changes in expression of SEAP and GFP by SC cells. SC cells were transduced with either eNOS-SEAP or eNOS-GFP adenovirus and subjected to low or high shear stress for 24 hours. (A) SEAP concentration in conditioned media was assessed by a chemiluminescent SEAP assay. Cellular GFP expression was measured using (B) flow cytometry and (C) confocal microscopy. Low shear = 0.1–1 dynes/cm2 and high shear = 10–12.5 dynes/cm2. Scale bar–50 µm. *P < 0.05., **P < 0.01.
