Abstract

Mechanical forces are key stimuli that dynamically adjust vessel distribution and diameter, but the precise mechanisms of force adaptation are unclear. This study identifies a biphasic response to cyclic stretch, consisting of an initial calcium-driven junctional mechanoresponse followed by mechanoadaptation facilitated by monolayer stiffening.
