Flow demo (T cell interaction with human in vitro BBB model under flow)
I attached a link to a short presentation regarding the flow movie setups. The figures and videos will be explained in detail during the meeting on Friday.

Introduction In our labs previously work, difficulties in growing endothelial cells (ECs) under shear flow lead to the exploration of novel membrane technologies that permit firm EC attachment, without compromising membrane permeability or leukocyte transmigration studies. We ultimately landed on the development of effectively ‘dual-scale’ membranes that contained 3 μm pores dispersed amongst an NPN…
The two barrier anatomy of the post-capillary NVU and why it matters At the post-capilliary venule, the blood-brain barrier (BBB) is actually two barriers in series: 1) one created by the pericyte/BMEC layer at the blood interface and 2) one created by astrocytes and the astrocyte-produced glia limitans at the interface with the brain. We’ll…
Introduction We are investigating some issues seen with long term attachment (up to 6 days) of the EECM-BMEC-like cells seen by collaborators in Bern, where they noticed black aggregates on the coated control devices that get worse at day 6. Some attachment issues and aggregates have also been seen at the University of Rochester in…
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…
Recently we have received dual scale (nanoporous and microporous) membranes from SiMPore at two porosities: 0.625% and 1.25%. These feature 3 µm circular pores (Lot 1383). We routinely perform QC checks on membrane deliveries, so the following is report on this delivery. First, I’d like to note that we were supposed to receive equal amounts…
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…

You do need to make an electronic box- I had one made by our department’s electronics guy.
Thanks for showing us your system- Always interested in seeing the clever ways people do this stuff!
