Functional response of iMAECs to shear stress. (A) Endothelial cell tube formation; (B) endothelial cell sprouting; and (C) endothelial cell scratch wound migration assay performed using iMAECs exposed to LS or OS for 24 h. Dotted black line in B denotes the periphery of the Matrigel bead for sprouting assay. Black scale bar = 200 μm. Cells under static condition were used a controls. Data shown as means ± standard error; n = 3; * p < 0.05.
