Imaging Engineering Tissue

Abstract:
A core challenge being addressed by the Imaging Thrust of the CELL MET Engineering Research Center is to answer the question: In engineered tissue platforms, how do we do volumetric imaging over wide fields of view with high resolution and at high speed? In this talk I will discuss the problem generically, beginning with three strategies for imaging volumetrically: widefield, confocal, and multiphoton microscopy. I will describe progress that we have made in particular for imaging modalities that are useful for engineered cardiac tissue. I will discuss the use of recently-engineered fluorescent voltage sensors to allow millisecond-scale temporal resolution in microscopy, and the advanced microscopes that we have been using to explore tissue structures. Finally, I will talk about cardiac micro tug (µTug) imaging and our progress in developing platforms for high-throughput screening, force measurement and control with optical feedback, and an all-optical non-contact tool for measuring tissue stiffness.
