A Microfluidic Platform for the Automated Multimodal Assessment of Small Artery Structure and Function

Yasotharan, Sanjesh 24 July 2012 (has links)
In this thesis, I present a microfluidic platform that enables automated image-based assessment of biological structure and function. My work focuses on assessing intact resistance arteries from the mouse cerebral vascular bed with a diameter of approximately 120µm in vitro. The experimental platform consists of a microfluidic device and a world-to-chip fluidic interconnect that minimizes unwanted dead volumes and eliminates the need for any liquid-filled peripheral equipment. The integrated platform is computer controlled and capable of fully automated operation once a small blood vessel segment is loaded onto the chip. Robust operation of the platform was demonstrated through a series of case studies that assessed small artery function and changes therein induced by incubation with the drug nifedipine, a dihydropyridine calcium channel blocker. In addition artery segments were stained for L-type calcium channels, F-actin and nuclei, from which structural information about cell alignment and shape was quantified.
