QC on Dual Scale Membrane (lot 1383)_from Bern
We recently received 100 Dual Scale Membrane (lot 1383). As noted in Dan’s post we also had same issues regarding mix up in the labeling. In the gel box, 2 boxes (25 membranes/box) are labeled 0.625% porosity and 2boxes are labeled 1.25% porosity, thus we supposed to have 50 membranes for both porosity. However 1…
Utilizing the μSIM to model brain endothelial barrier changes in Cerebral Amyloid Angiopathy
Introduction Vascular hyperpermeability and hemorrhagic stroke are hallmark symptoms of Cerebral Amyloid Angiopathy (CAA), a cerebrovascular disease characterized by amyloid-β deposition around the brain microvasculature. In CAA pathogenesis, vascular Aβ accumulation contributes to structural alterations and loss of integrity in the neurovascular unit/blood-brain barrier (NVU/BBB) resulting in “leakier” blood vessels, intracerebral hemorrhages, increased risk of…
Fibronectin and Friends: Confirming the Presence of Multiple Vascular Basement Membrane Components in the μSiM-hNVU
Introduction The blood-brain barrier (BBB) plays an important role in maintaining brain chemistry by restricting the permeability of small molecules and cells. Inflammatory diseases may disrupt the BBB and promote the development of neurological disorders [1]. One potential mechanism of BBB disruption is the degradation of the extracellular matrix proteins that make up the vascular…
A Modular vascular barrier platform with a removable flow module and high resolution imaging (Publication draft)
1. Introduction 1.1 Vascular barriers Functions: Maintain tissue homeostasis, control transport and gas exchange, recruit immune cells during inflammation Figure 1. Schematic illustration of a vasculature barrier in the human body. Endothelial cells as a building element of vasculature barriers line up along the vessel walls and separate the vessel from the tissue. Different stages…
ALine mod-µSiM: Version2
Modular µSiM Version 2 (V2) Holds ~30 µl of media in the bottom channel. Designed for cocultures, ELISAs, and other assays that are easier with greater channel media volumes. For more surface area and volume information on mod-µSiM V2, see ALine Modular Device Geometry. Passive Pumping Another feature of V2 devices is their ability to…
Phase Contrast Microscopy Image Correction for Neutrophil Transmigration Studies
Introduction Selective leukocyte interactions with endothelial barriers are a characteristic component of the inflammatory response process. These spatio-temporal interactions can mechanically remodel local tissue, as well as damage healthy tissue with robust inflammation stemming from an over-reactive immune response. This is evident in many pathologies and can complicate severe conditions such as sepsis. Thus, it…
