Cell Orientation Relative to Patterning and Flow Direction. Orientation of HUVECs across directional nanowell surface topography under sequential flow conditions. Angle measurements were taken as the long axis of each ellipse-fitted HUVEC relative to the flow direction, or to the horizontal in the case of 48 h static condition.
