'"Stimulated actin polymerization" has been proposed to be involved in force augmentation, in which prior submaximal activation of vascular smooth muscle increases the force of a subsequent maximal contraction by ~15%. In this study, we altered stimulated actin polymerization by adjusting tissue length and then measured the effect on force ... More
