This paper concerns the electrochemical modeling of vascular smooth muscle cells. The aim is to describe the influence of cell stretch on the intracelluar calcium concentration. A state-of-the-art cell model is extended by a stretch-activated sarcolemmal channel. Two representations for this channel are developed which describe several electrical and chemical cell membrane properties. The unknown parameters of the new channels are identified by comparing the simulation results with experimental data. The extended cell model shows a typical transient behavior for stretch stimulation. As the most important characteristic it reflects the generation of action potentials induced by cell elongation.
