Fig. 5From: Challenges of aortic valve tissue culture – maintenance of viability and extracellular matrix in the pulsatile dynamic microphysiological systemPulsatile dynamic culture medium propulsion: The pneumatic pump cycle is illustrated and the flow rates in high flow setup (A) and low flow setup (B) were measured by particle image velocimetry (PIV). Cycle-specific shear forces were computed (filled circle: pneumatic pressure applied, empty circle: vacuum applied; Abscissa: seconds)Back to article page
