Endothelial Response to Increased Shear Stress Frequency

Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress frequency (2 Hz) was then applied. The transcriptomics studies using microarray identified genes that were sensitive to the elevated shear frequency. keywords: adaptation, shear stress, frequency, microarray, gene expression Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress magnitude (2 Hz) was then applied. Gene expression at multiple time points was measured using microarray.
