Abstract: The present disclosure relates to tissue supports for use with engineered tissues and organoids, such as cardiac organoid chambers. In an embodiment of the present disclosure, the tissue supports are provided with a fluid-impermeable resilient member that is resiliently deformable during testing by cultured tissues formed on the surface of the tissue support.

Abstract: The present disclosure relates to a sample analysis device for increasing measurement resolution of forces generated by a sample and method of use thereof. The sample analysis device comprises a body stretchable along a central longitudinal axis. The body includes at least one attachment region engageable with a sample and a plurality of stretchable portions spaced apart by joining regions. The body also includes at least one detectable datum for determining displacement. Each stretchable portion extends generally longitudinally and includes an offset region inclined to the longitudinal axis. The stretchable portions increase the compliance of the body within a predetermined measurement range.

Abstract: The disclosure provides a device for developing organized tissue strips, such as cardiac tissue strips, for high-throughput assays of functional performance and the methods involved in fabricating, assembling, implementing, utilizing and analyzing data from such assays. The disclosure further provides systems for constructing such devices, systems comprising those devices comprising cells and extracellular matrix material for developing organized tissue strips or comprising the devices and organized tissue strips. The disclosure further provides methods for assaying a property of a tissue strip, such as contractile force.
