We present a new model for inositol triphosphate $\rm (IP_{3})$-induced cytosolic $\rm Ca^{2+}$ oscillations in non-excitable cells. The model includes the various $\rm Ca^{2+}$ in- and efflux pathways reported to exist in these cells. In particular, it features the complex regulation of the $\rm Ca...
