A microcomputer-based device to simulate biomechanical environments for cultured cells

We describe software and hardware for a microcomputer-based cyclic strain device which applies programmed cycles of elongation and relaxation to cultured cells. This system has the potential to simulate many of the complex mechanically active environments found in living systems. As a sample application, we use it to simulate the cyclic stresses to which vascular smooth muscle cells in the arterial system are exposed.
