Pathophysiological significance of coronary collaterals for preservation of the myocardium during coronary occlusion and reperfusion in anaesthetised dogs.

abstract：OBJECTIVE:Activin-like kinase receptor 1 (ALK1) is a transforming growth factor (TGF)-beta type I receptor expressed in vascular mesenchyme, yet its function in vascular mesenchymal cells (VMC) is unclear. We examined ALK1 expression in human coronary atherosclerotic lesions and bovine and human VMC undergoing cellular...
