[Novel approach to studying relationship of 3D structure and mechanical properties of biological tissue]

We present here a novel approach to studying the relationship of three-dimensional structural organization of myocardial tissue as an example of biological tissue and its mechanical properties. The approach consists in the correlation of image series of the preparation internal structure obtained by confocal laser scanning microscope LSM-710 and the registration of tension-deformation properties of the preparation. The spatial structure images of the segment of rat right ventricular wall at different stretching levels have been obtained. It is shown that the proposed approach provides the possibility to study the mechanisms of tension and strain development in living biological tissues in more detail.
