av L Jönsson · 2011 · Citerat av 15 — Through using a stented SIS tube as a circumferential esophageal replacement in a piglet model, this study suggests that pericytes from ingrowing capillaries

Guimarães-Camboa et al. permanently labeled pericytes and vascular smooth muscle of multiple organs in vivo and followed the fate of these cells in aging and injury models. Their analyses showed that, in vivo, pericytes did not behave as stem cells, challenging the current view of pericytes as tissue-resident multipotent progenitors.

Here, we demonstrate that pericytes localized at capillary junctions in a postarteriole transitional region possess unique properties, notably including contractility, that enable Blod-hjärnbarriären är mycket tätt sammanfogade kapillärväggar i hjärnans blodkärl som skyddar hjärnvävnaden. Blod-hjärnbarriären hindrar vissa droger, läkemedel och celler (till exempel vita blodkroppar, mikroorganismer) från att lämna blodbanan och nå hjärnans nervceller. Pericytes are one of the two cell types that form the blood vessel. The other being endothelial cells, which form the inner lining of the vessel wall. Pericytes, or perivascular cells, are vascular smooth muscles cells that surround endothelial cells.

Pericytes

Pericytes are one of the two cell types that form the blood vessel. The other being endothelial cells, which form the inner lining of the vessel wall. Pericytes, or perivascular cells, are vascular smooth muscles cells that surround endothelial cells. Pericytes regulate the development of organ-specific characteristics of the brain vasculature such as the blood–brain barrier (BBB) and astrocytic end-feet.

Pericyte Markers Pericytes: Specialized mesenchymal cells (mesodermal origin) associated with the walls of blood vessels including capillaries of the blood-brain barrier.

They provide an incomplete investment to endothelial cells, thus reinforcing vascular structure and regulating microvascular blood flow. Pericytes exert an important role on endothelial cell proliferation, migration and stabilization. 2015-10-14 Pericytes are required for blood-brain barrier integrity during embryogenesis.

Pericytes cover between 22% and 99% of the endothelial cell surface. One of the slender mesenchymallike cells found in close association with the outside wall of postcapillary venules; it is relatively undifferentiated and may become a fibroblast, macrophage, or smooth muscle cell.

Synonym (s): adventitial cell. [ peri- + G. kytos, cell] Medical Dictionary for the Health Professions and Nursing © Farlex 2012 Pericytes are cells that wrap around the endothelial cells that line the capillaries and venules throughout the body. They are located in the basement membrane which allows them to communicate very Pericytes are cells present at intervals along the walls of capillaries (and post-capillary venules).

These cells maintain vascular function. Microvascular changes often involve pathological pericyte activation and bloodbrain barrier dysfunction.

Therefore, pericytes likely play a prominent role in lung physiology given their localization in the perivascular niche. New genetic approaches have increased our understanding of the origin and the diverse functions of lung pericytes. Lung pericytes are myofibroblast progenitors, contributing to development of fibrosis in mouse models.

Pericytes in the microvasculature. Hirschi KK(1), D'Amore PA. Author information: (1)Children's Hospital, Department of Pathology, Harvard Medical School, Boston, MA 02115, USA. Pericytes, also known as Rouget cells or mural cells, are associated abluminally with …

1,23 The processes are circumferential, forming a mesh around the 2013-03-28 · Pericytes play essential roles to maintain functional vessels to support tumor growth. Tumor pericytes are thought to be derived from their progenitors from the surrounding normal tissue or from the bone-marrow-derived cells homing in tumors after treatments (De Palma et al., 2005; Du et al., 2008). Pericytes in neurodegeneration Abstract The brain microvasculature is formed of different cell types, where endothelial cells, forming the vessel tube, are encircled by pericytes. Both cell types are ensheathed in a basal lamina, and covered by astrocyte end-feet and Pericytes are uniquely positioned at the blood-brain interface. These cells maintain vascular function. Microvascular changes often involve pathological pericyte activation and bloodbrain barrier dysfunction.

Injecting pericytes into muscles makes them bigger and stronger, American scientists discovered. 1 Pericytes in neurodegeneration Thomas Padel DOCTORAL DISSERTATION by due permission of the Faculty of Medicine, Lund University, Sweden. To be defended on September 28th, 2017, at 9:00, Segerfalksalen, Wallenberg Neuroscience Center, Lund University, Lund, Sweden. Intriguingly, venular pericytes are not the only ones that interact with and influence leukocytes during inflammation. Stark et al. delineated a role for arteriolar and capillary pericytes in the murine skin microcirculation in potentiating leukocyte responses to inflammatory stimuli using intravital two-photon microscopy of NG2-DsRed-CX 3 CR1-GFP and NG2-DsRed-LysM-eGFP mice [].
