Beyond the adventitia: exploring the outer limits of the blood vessel wall.
The anatomy of the arterial wall has traditionally been divided into 3 distinct regions, forming concentric layers surrounding the blood vessel lumen. The intima, consisting of a single layer of endothelial cells in direct contact with the lumen; the media, containing layers of smooth muscle cells and extracellular elastin fibers; and the adventitia, composed largely of collagen and other extra...
متن کاملCXCR3-dependent accumulation and activation of perivascular macrophages is necessary for homeostatic arterial remodeling to hemodynamic stresses
Sustained changes in blood flow modulate the size of conduit arteries through structural alterations of the vessel wall that are dependent on the transient accumulation and activation of perivascular macrophages. The leukocytic infiltrate appears to be confined to the adventitia, is responsible for medial remodeling, and resolves once hemodynamic stresses have normalized without obvious intimal...
متن کاملDelivery site of perivascular endothelial cell matrices determines control of stenosis in a porcine femoral stent model.
PURPOSE Endothelial cells, grown within gelatin matrices and implanted onto the adventitia of injured vessels, inhibit stenosis in experimental models. To determine if this technology could be adapted for minimally invasive procedures, the authors compared the effects of cells in an implantable sponge to that of an injectable formulation and investigated the importance of delivery site in a ste...
متن کاملPrimary perivascular epithelioid cell tumor of the liver not related to hepatic ligaments: hepatic PEComa as an emerging entity.
Primary perivascular epithelioid cell tumor (PEComa) of the liver is a very rare example of an emerging family of hepatic PEC tumors. Only few cases have been described so far. We report the case of a large but benign hepatic PEComa in a 53-year-old man without signs of tuberous sclerosis. In contrast to recently described PEC-derived liver tumors in children and young adults, this neoplasm was...
متن کاملIdentification and Characterization of Novel Perivascular Adventitial Cells in the Whole Mount Mesenteric Branch Artery Using Immunofluorescent Staining and Scanning Confocal Microscopy Imaging
A novel perivascular adventitial cell termed, adventitial neuronal somata (ANNIES) expressing the neural cell adhesion molecule (NCAM) and the vasodilator neuropeptide, calcitonin gene-related peptide (CGRP), exists in the adult rat mesenteric branch artery (MBA) in situ. In addition, we have previously shown that ANNIES coexpress CGRP and NCAM. We now show that ANNIES express the neurite growt...
