Stiff Substrates Enhance Endothelial Oxidative Stress in Response to Protein Kinase C Activation
Figure 6
Reticular adherens junction loss was greater in cells on stiffer substrates following PMA. PAEC monolayers on 6, 14, or 29 kPa gels were treated with 1 μM PMA for 15 or 30 minutes, prior to fixation and immunofluorescent labeling of the cell-cell junction protein β-catenin.
