Abstract
Endothelial cell (EC) injury and the response of EC and smooth muscle cells (SMCs) to injury contribute to the pathophysiology in patients with vascular disease and atherosclerosis. Since platelets have been suggested to play an important role in modulating vascular injury, the present study was undertaken to examine the influence and mechanism of action of individual platelet factors on bovine aortic EC and SMC migration using an in vitro wound assay system. Serotonin decreased EC proliferation and reduced EC migration 21 +/- 1% (p less than 0.005), which was attenuated by imipramine. Transforming growth factor-beta reduced EC proliferation and decreased EC migration 52 +/- 3% (p less than 0.005). Norepinephrine increased EC proliferation but decreased EC migration 26 +/- 2% (p less than 0.005), which was abolished by phenoxybenzamine. Histamine increased EC proliferation but reduced EC migration 29 +/- 2% (p less than 0.005), which was attenuated by diphenhydramine. Platelet-derived growth factor decreased EC proliferation and decreased EC migration 40 +/- 2% (p less than 0.005). In contrast, serotonin increased SMC proliferation and increased SMC migration 31 +/- 2% (p less than 0.005), which was abolished by ketanserin. Transforming growth factor-beta increased SMC migration 35 +/- 5% (p less than 0.005). Norepinephrine increased SMC proliferation and increased SMC migration 43 +/- 4% (p less than 0.005), which was abolished by propranolol. Histamine increased SMC proliferation and increased SMC migration 38 +/- 3% (p less than 0.005), which was abolished by cimetidine. Platelet-derived growth factor increased SMC proliferation and increased SMC migration 40 +/- 3% (p less than 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)This publication has 30 references indexed in Scilit:
