SARASOTA, Fla. & LONDON--(BUSINESS WIRE)--World Precision Instruments Inc today announced the launch of the new Cell Tester, a novel cell biology research tool, set to revolutionize the emerging field of ‘mechano transduction’ by allowing researchers to study the influence of mechanical force, stress or strain on cells and how these cells react to stimuli. The resulting data will help answer fundamental questions such as how do individual muscle cells sense stress and stretch? And how does this contribute to the heart’s ability to adjust pumping capacity as a function of the fluid filling state?
