The Tissue Stretcher stimulates cells grown in hydrogel tissue constructs through repetitive mechanical strain. Tissues, stretched up to 40 percent by a pulsing motion, mimic the physical conditions for cardiac tissue, but can be adjusted for different stroke length and speed, as well as altogether different applications. The stretcher platform has the ability to stretch up to 32 separate tissues, utilizing special 3D suspended culture wells via the MC-8™. Together with the Palpator™, these two products can produce the mechanical stimulation and measurement data needed for future drug discovery and regenerative medicine.

Analysis of Cardiac Physiology
Excitation-Contraction-Energy (ECE) Coupling
An electrical stimulation, i.e., action potential initiates cardiac contraction. Intracellular Ca2+-transient couples action potential and cardiac contraction. Cardiac contraction is also coupled to mitochondria that replenish energy (i.e., ATP) and recycle metabolites (ADP and Pi). InvivoSciences analyzes all those parameters to determine drug-induced or genetically driven changes in ECE coupling.

Ultra-Rapid Plate Reader, FDSS/μCell (Hamamatsu)
Our in-house FDSS/μCELL analyzes fluorescent/luminescent signals from all the well of a 96/384-well plate simultaneously, enabling ultra-rapid measurements of cardiac physiology.
With a multi-channel electric field stimulation (EFS) device, FDSS/μCELL is used to measure high-throughput phenotyping of cardiomyocytes and neurons derived from human iPSC.
