The cell attachment strength study. A The micro photos and B the percentage of HUVECs remaining adhered to the channel exposed to increasing shear stress for various time periods. Each shear stress lasted four minutes before further increase. C The micro photos and D number of adhered cells in channels with different shear stress (0.17, 3.9, 8.3, and 16.7 dyn/cm2) for upto 24 h
