Mimicking life on a microscale
14 million: the amount of deaths every year worldwide because of thrombosis-related heart attacks or strokes. To better understand and combat thrombosis, we need to gain more knowledge.
Blood flow patterns and 3D geometry of blood vessels play a key role in the mechanism of thrombosis. If we can create a small scale in vitro model of healthy ánd affected blood vessels, we can help healthcare in improving treatment and diagnosis. An organ on a chip, so to speak.
Jetting technology can be used to literally create an artifical organ on a chip. Using CT image data, a printer can produce a three-dimensional “carbon copy” of blood vessels on a microfluidic chip, which is then coated with human cells.
The result: an in vitro lab model3 of human blood vessels, ready to help healthcare move forward.
Gatekeeper of the brain
A unique feature of our bodies: the blood-brain barrier (BBB). Between the blood and the surrounding nervous tissue, it functions as the perfect gatekeeper: optimizing conditions and keeping toxins out.
In several neurodegenerative diseases, the BBB-functionality is disturbed. How? We’re not sure yet.
By mimicking the gatekeeper on a microscale, we can get a better understanding of the barrier function of the BBB. The BIOS Lab on a chip Group in Twente developed a microfluidic platform to model both biochemical and mechanical stress in the barrier: a micro-environment, containing real life brain cells.
Using the principles of nanofluidic transport, we now have a model to study the brain-gatekeeper. How do diseases work, and how can we evaluate drug passage and in that way also gain insight in the treatment of these neurodegenerative diseases.
Dutch physicist Albert van den Berg is a professor of microand nanofluidics, lab-on-a-chip technologies and applications at Twente University. There, he heads the BIOS Research Group at the MESA+ Institute for Nanotechnology. In 2014 he was appointed scientific director of the MIRA institute for Biomedical Engineering.
