2018-03-09 · The functions and capabilities of pericytes are impressive and, as yet, incompletely understood. Molecular mechanisms responsible for pericyte-mediated regulation of vascular stability, angiogenesis and blood flow are well described while their regenerative and immunomodulatory characteristics are still not completely revealed.

2019-06-06 · Pericytes of the blood–brain barrier (BBB) are embedded within basement membrane between brain microvascular endothelial cells (BMECs) and astrocyte end-feet. Despite the direct cell–cell contact observed in vivo, most in vitro BBB models introduce an artificial membrane that separates pericytes from BMECs.

The role of pericytes in blood-brain barrier function and stroke. Central nervous system pericytes have critical and complex inductive, structural, and regulatory roles interacting with other cell types of the neurovascular unit, especially endothelial cells and astrocytes. Se hela listan på frontiersin.org 2016-05-26 · Pericytes are vascular mural cells embedded in the basement membrane of blood microvessels. They extend their processes along capillaries, pre-capillary arterioles and post-capillary venules. CNS Pericytes are perivascular cells that line the abluminal surface of the microvasculature.

Pericytes function

Pericytes are highly heterogeneous cells in terms of phenotype, tissue distribution, origin and functions, and they play an important role in the regulation of vascular morphogenesis and function. Pericytes were shown to be involved in tissue development and homeostasis, as well as in pathological processes, including atherosclerosis. 2019-06-06 · Pericytes of the blood–brain barrier (BBB) are embedded within basement membrane between brain microvascular endothelial cells (BMECs) and astrocyte end-feet. Despite the direct cell–cell contact observed in vivo, most in vitro BBB models introduce an artificial membrane that separates pericytes from BMECs.

Pericytes are embedded in the basement membrane of small blood vessels including capillaries, pre-capillary arterioles and post-capillary venules2. Though the cells themselves were origi-nally described by Charles Rouget, the term “pericytes” was coined by Pericytes are, however, functionally significant; when vessels lose pericytes, they become hemorrhagic and hyperdilated, which leads to conditions such as edema, diabetic retinopathy, and even embryonic lethality.

Migratory function: Pericyte movement to endothelial cells during vascular development is mediated by endothelial-derived PDGF-β and PDGF-β receptors expressed by pericytes. 7 Pericyte-to-endothelial migration is readily demonstrable in cell culture preparations using in vitro capillary-like structures, as shown in Figure 3. 8 After traumatic brain injury, approximately 40% of brain

Pericytes are embedded in the basement membrane . of small blood vessels including capillaries, pre-capillary arterioles Se hela listan på news-medical.net Pericytes and myogenesis. Pericytes contribute to the formation of skeletal muscle. Transplanting pericytes into host muscle causes them to fuse with myoblasts to form myotubes, which helps to regenerate muscle in cases of injury or necrosis. Pericytes can be cultured in vitro, so they can be used to treat muscular dystrophies. As an important component of vascular tubes, pericytes exhibit myriad different functions, such as vessel stabilization, multiple‐lineage differentiation capacity, and angiogenic stimulation (1). These functions, however, are highly variable and diverse in different tissues/organs and developmental stages.

More recently, numerous vascular functions of pericytes have been identified including regulation of cerebral blood flow, maintenance of the blood-brain barrier (BBB), and control of vascular development and angiogenesis. Pericytes can also facilitate neuroinflammatory processes and possess stem cell-like properties.
