Investigation of principles of mechanotransduction in living animal cells creates a basis for understanding processes in cardio-vascular system such as tissue remodelation, atherosclerotic changes, growth of aneurysms, etc. To be able to estimate the biochemical response of the cell or tissue on a mechanical load, we need to determinate the very quantity (or set of quantities) that is responsible for this response. As cell is a complex structure with numerous components, it cannot be expected that this quantity will be found on the base of homogeneous continuum models. Therefore more complex (structural) finite element models of the mechanical behaviour of cells are needed. A new more realistic model of cytoskeleton has been created. The model should be able to simulate various mechanical tests of isolated cells. In future various types of tests carried out with the same type of cells (vascular smooth muscle cells) should be simulated with the aim to identify constitutive parameters of the individual components of the model.
