Although compromise of endothelial integrity occurs through many mechanisms, mechanical removal by balloon catheter is an excellent experimental method to study vascular responsiveness after injury. The interaction of platelets with the vessel wall, as well as proliferation of vascular smooth muscle cells can be assessed in this model. Following platelet attachment to the subendothelium, platelets release materials from their alpha granules. Using an antibody raised against platelet factor 4, a protein stored in alpha granules, we have demonstrated that material released from platelets do enter the vessel wall. A large amount of PF 4 antigen enters the wall shortly after endothelial removal, permeating the wall completely by 30 minutes, but little trace of the antigen can be found four hours after injury. Using infusions of PGI2 to a level of 850 ng/kg/min in rabbits, in vivo platelet adhesion to the exposed subendothelium can be greatly reduced and release of PF4 antigen into the vessel wall markedly diminished. Growth of smooth muscle cells (SMC) after endothelial removal has also been measured by 3H-Thymidine labeling of SMC DNA. As measured by this method as well as direct cell counts, SMC proliferation in the abdominal aorta is significantly greater than the thoracic. Reinjury of only the abdominal aorta by balloon catheter 4 days after the initial total aortic injury causes a proliferative spurt in the thoracic aortic SMC, thus demonstrating that a humoral signal can initiate SMC proliferation. In addition, the response of SMC from 21 month old rats when compared with 3 month old rats is much greater. These studies demonstrate in vivo methods for examining the response of platelets and SMC following endothelial injury. Further, these studies indicate that the response to injury hypothesis of atherosclerosis progression should now be broadened to the concept of a response to signal view of atherogenesis.
