The battlefield at arteriovenous crossroads: invading arterial smooth muscle cells occupy the outflow tract of fistulas

There is an ongoing debate about the anatomical origin of the neointimal cells that are responsible for venous stenotic lesions in arteriovenous fistulas. Liang and co-workers show that vascular smooth muscle cells from the feeding artery contribute substantially to venous intimal hyperplasia in a murine AVF model. In addition, they show that increased Notch signaling is the driving force behind FSP-1-mediated migration of these cells to the venous outflow tract.
