In the vascular system, Nox1 mRNA has been detected mainly in vascular smooth muscle cells but not in adventitial cells, whereas Nox2 is localized primarily in endothelial and adventitial cells, and Nox4 is abundantly expressed in all of the vessel constituents [55-57].
It is obvious that these elements are the adventitial cells of the capillaries or the pericytes of Zimmermann(21)--a cell type which recently has received much attention and which by some investigators is made responsible for the contractility of the capillaries.
distinguished two populations within the IFP stem cells: the pericytes (CD31-/CD34-/CD45-/CD146+) and adventitial cells (CD31-/CD34+/CD45-/CD146-), corresponding to 3.8% and 21.2% of the isolated cells at the stromal vascular fraction (SVF).
