Abstract :

V ascular growth and remodeling occur in association with certain physiological and pathological conditions. In addition, vascular regeneration and repair are essential for the survival of blood vessels. These processes involve numerous cell types. We have shown that a population of adventitial neuronal somata (ANNIES) expressing the neural cell adhesion molecule (NCAM) and the vasodilator neuropeptide, calcitonin gene-related peptide (CGRP), possibly of sensory nerve origin, is located in small mesenteric arteries. The vascular adventitia is a complicated tissue, which is found to be the most active layer in terms of cell turnover. Recent research reports suggest that stem or progenitor cells reside in the vessel wall, and specifically shown in ?vasculogenic zone?? within the vascular adventitia. Further, endothelial progenitor cells (EPCs) and hematopoietic stem cells (HSCs) were shown to co-exist within the vascular adventitia. This study suggests a symbiotic association of HSCs and EPCs in the vascular wall as in adult bone marrow. Here, we examined whether the adventitia of the adult rat mesenteric artery expresses HSCs, and mesenchymal stem/progenitor cells, and identified CD45+ and ckit+ cells using fluorescent confocal microscopy. The mesenteric arterial adventitia harboring CD45+ hematopoietic stem cells, ckit+ mesenchymal stem/progenitor cells and CGRP-containing neural cells may participate in vascular and peripheral nerve injury and regeneration
