Krautler and colleagues isolated pure vascular mural cell populations from fat tissue of mice, which were then introduced into collagen sponges.
In blood vessels, matrix scaffold degradation is mediated by activation of MMPs to facilitate endothelial and mural cell migration and invasion.
Different molecules and pathways have been involved in mural cell motility and adhesion.
Cerebral aneurysms are characterized by disruption of the internal elastic lamina (IEL), phenotypic modulation of smooth muscle cells (SMCs), apoptosis of mural cells, and extracellular matrix (ECM) degradation, which are considered as the hallmarks of CA [24].
Interestingly, it has variously been shown that mural cells, such as mesenchymal stem cells (MSCs), or fibroblasts further promote the vascularization process [9, 10, 13, 15].
Furthermore, T[beta]4 was shown to facilitate angiogenic sprouting, by activating SRF target genes via the nuclear translocation of MRTF-A [11], and to foster the attachment of mural cells to endothelial cell tubes, improving the functionality of vessels [12,13].
Recent data from our team and others drew new attention on a discrete population of mesenchymal cells that wraps around vessels, variously called mural cells, perivascular cells or pericytes, as a major source for profibrotic stromal cells generating scar tissue.
On the other hand, it is known that apoptosis can occur in at least four different follicular compartments, theca cells, mural cells, cumulus cells and in the oocyte (12) and that ovarian follicles with identical morphology have different apoptosis levels in mural granulosa and cumulus cells (25).
