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.

One of the many contributions Alec S. made to our group is to help us appreciate the importance of the apicobasal (A/B) polarity of endothelial cells. The effects of A/B polarity were demonstrated in his paper: Integrative Biology (2020), 12(11),275–289 where he showed that stimulation of ECs with TNFα from the abluminal chamber caused an…
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…
Introduction/Methods As part of our investigation into neutrophil transmigration on tissue chip systems featuring HUVEC monolayers, I have been working on developing code for both cell state analysis and tracking using Wolfram Mathematica (and occasionally Python). This project relies on semantic segmentation via machine learning and microscopy video corrections, both of which have been described…
1. Introduction Fluid flow is one of the key elements of vascular models for delivering nutrients and growth factors to cells as well as introducing other components like neutrophils. In post 1, we described our modular design for incorporating a flow module into the uSiM device. Then, we presented fluid flow simulation and its experimental…
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…

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!
