Methods In this paper we focus on the direct role of thrombin as a mitogen for smooth muscle cells (SMCs) derived from different vessels from the vascular tree (coronary artery, aorta, carotid artery and …
Webbsence of nifedipine and SKF96365 also showed similar lack of responses in trachea. Interestingly, removal of stored calcium did not affect the carbachol responses (p>0.05). From these observations, we conclude that the role of stored and extracellular calcium in Gq protein activation is not the same across different type of smooth muscle tissues.

Webb6 juli 2015 · Grutzendler and colleagues investigated the role that smooth muscle cells might play in stroke by tying off the middle cerebral artery in transgenic mice for 90 minutes. They found that smooth muscle cells on precapillary arterioles clamped down on vessels in response, blocking the flow of red blood cells to downstream tissues. Webb1 apr. 2001 · Recent evidence suggests an important role for membranous invaginations termed caveolae, and their integral protein components caveolins, in the coordination of extracellular contractile stimuli and intracellular effectors in smooth muscle.
