So far, extensions of these models have been proposed to include either intracellular signaling or chemo-mechanical coupling on the organ-scale. However, no version of constrained mixture models currently exists that includes both aspects. Here, we propose such a version that resolves cellular signal processing by a set of logic-gated ordinary differential equations and captures chemo-mechanical interactions between cells by coupling a reaction-diffusion equation with the equations of nonlinear continuum mechanics. To demonstrate the potential of the model, we present 2 case studies within vascular solid mechanics: (i) the influence of angiotensin II on aortic growth and remodeling and (ii) the effect of communication between endothelial and intramural arterial cells via nitric oxide and endothelin-1.en1617-79402024621152136Springerhttps://creativecommons.org/licenses/by/4.0/Cell signaling | Constrained mixture | Growth and remodeling | Homeostasis | Soft tissueTechnology::660: Chemistry; Chemical Engineering::660.6: BiotechnologyJournal Articlehttps://doi.org/10.15480/882.1383010.1007/s10237-024-01884-w10.15480/882.13830Journal Article
