The present application provides systems and methods for measuring cell function or tissue function. More particularly, the present application provides systems and methods for determining cell or tissue contractility using ultrasound; systems and methods for measuring the effect an agent has on cell or tissue contractility using ultrasound; and systems and methods for determining material properties of a material using ultrasound.

Systems and methods for determining cell contractility

A microfluidic device, method and kit for assaying and/or culturing cells are provided. The microfluidic device comprises a well block comprising a plurality of microwells; at least one cell culture layer selected from a first cell culture layer comprising a plurality of microchannels, each microchannel being aligned with one of the plurality of microwells and being in fluid communication with the aligned microwells; and a second cell culture layer comprising a plurality of cell culture chamber wells, each cell culture chamber well being aligned with one of the plurality of microwells and being in fluid communication with the aligned microwells, and a plurality of outlets, each of the plurality of outlets corresponding to one of the plurality of cell culture chamber wells; and a base block, wherein the at least one cell culture layer is sealably coupled between the well block and the base block, thereby allowing fluid communication between the plurality of microwells in the well block and the at least one cell culture layer.

Microfluidic device for cell-based assays

The present invention details the design and operation of a miniaturized device array in which a range of simultaneous mechanical forces are produced by a single external pressure source. The invention is primarily embodied in a microfabricated device arrays designed to rapidly probe biological cell response to various combinations of mechanical, chemical and extra-cellular matrix parameters in a high-throughput fashion.
