Pericytes regulate the blood-brain barrier - Göteborgs

Current in vitro BBB models fail to replicate this restrictive behavior due to poor integration of the endothelial cells with supporting cells (pericytes and astrocytes) following the correct anatomical organization observed in vivo. We report the coculture of mouse brain microvascular endothelial cells (b.End3), pericytes, with/without C8-D1A astrocytes in layered microfluidic channels forming three-dimensional (3D) bi- and triculture models of the BBB. Here, we provide that the recruitment of pericytes and astrocytes to vascular tube of endothelial cells is closely associated with the formation of tight junction in developing retinal vessels. At P4, endothelial cells of retinal vessels behind the invading front directly contact to pericytes, but not to foot processes of astrocytes, where ZO‐1 was already weakly immunoreactive along retinal endothelial cells. Brain microvascular cells such as brain microvascular endothelial cells (BMEC), pericytes, and astrocytes are major components of the blood–brain barrier (BBB). The BBB regulates substance transport from the blood into the brain and is involved in the progression of many neurological diseases. Most studies have focused on neurons while ignoring the important roles of other cells of the neurovascular unit, such as astrocytes and pericytes.

In this case, investigators used our human brain microvascular pericytes (Cat.#HMP104) and human brain astrocytes (Cat.# HMP202) when looking into the pathogenesis of malaria.

We generated a human iPSC-derived model of the BBB that includes endothelial cells in co-culture with pericytes, astrocytes and neurons. Evaluation of barrier We generated a human iPSC-derived model of the BBB that includes endothelial cells in coculture with pericytes, astrocytes and neurons. Evaluation of barrier The BBB consists of endothelial cells lining the brain vasculature, supported by astrocytes and pericytes, and regulates transport into and out of the central The CNS microvascular pericyte: pericyte-astrocyte crosstalk in the regulation of astrocytes induce endothelial cell and per-icyte differentiation, but pericytes Moreover, an astrocytic inflammatory response, which reduces the survival of pericytes through an IκB kinase–dependent pathway, mediates the low pericyte Astrocytic end-feet are in contact with the basal membrane.

We set up a high-reproducible human-based in vitro BRB model using retinal pericytes, retinal astrocytes, and retinal endothelial cells in order to replicate the human in vivo environment with the same numerical ratio and layer order. In essence, pericytes seem important as structural support in the microcirculation and in BBB function. Pericytes have been considered to be significant in the pathogenesis of tissue damage in hypoxia, hypertension, diabetic retinopathy, trauma, Alzheimer’s disease, multiple sclerosis, and in CNS tumor formation [7, 12 13 14]. Furthermore, pericytes did not increase tightness of EC monolayers, whereas astrocytes did regardless of their seeding location.

The basal lamina provides mechanical support for cell attachment, serves as a substratum for cell migration, separates adjacent tissue, and can act as a barrier to the passage of macromolecules. To address whether astrocyte numbers were impacted in mice lacking Bcl-2 expression in pericytes or astrocytes, retinas from P21 mice were wholemount stained with anti-Pax2 and the numbers of Pax2 2010-09-08 Pericytes and Astrocytes Crosstalk: Understanding Perivascular Synergism at the BBB.

Crosstalk among brain endothelial cells (BECs), pericytes, and astrocytes occurs by way of soluble factors, including cytokines. Here, we studied cytokine secretion from both mouse BEC monocultures and tri-cultured with pericytes and astrocytes. Four cytokines were constitutively secreted by BEC mon … 2016-03-01 · Importantly, the pericytes and astrocytes convey cues that are required for normal function and differentiation of the brain microvascular endothelium [ 6, 7 ], and all three cell types—endothelial cells, pericytes, and astrocytes—are required for maintenance of the normal physiology of the neurovasculature and maintenance of BBB integrity in vivo as well as in vitro [ 5, 8 ]. Here, we provide that the recruitment of pericytes and astrocytes to vascular tube of endothelial cells is closely associated with the formation of tight junction in developing retinal vessels.
