The aim of the present study was to determine effect of two decellularized agents, sodium dodecyl sulphate (SDS) and Triton X-100, to the skeletal muscle tissue. Final scaffold was evaluated by several histological techniques to analyse preservation of essential structures including collagen and elastic fibres, basement membranes, glycosaminoglycans and also to confirm elimination of nuclear and cytoplasmic components which are redundant in effectively prepared decellularized scaffolds. Comparison of tissue scaffolds processed with different detergents proved that SDS is superior to Triton X-100 as it can effectively decellularize muscle tissue.

The cell culture became an invaluable tool for studying cell behaviour, development, function, gene expression, toxicity of compounds and efficacy of novel drugs. Although most results were obtained from cell cultivation in two-dimensional (2D) systems, in which cells are grown in a monolayer, three-dimensional (3D) cultures are more promising as they correspond closely to the native arrangement of cells in living tissues. In our study, we focused on three types of 3D in vitro systems used for cultivation of one cell type. Cell morphology, their spatial distribution inside of resulting multicellular structures and changes in time were analysed with histological examination of samples harvested at different time periods. In multilayered cultures of WRL 68 hepatocytes grown on semipermeable membranes and non-passaged neurospheres generated by proliferation of neural progenitor cells, the cells were tightly apposed, showed features of cell differentiation but also cell death that was observable in short-term cultures. Biogenic scaffolds composed of extracellular matrix of the murine tibial anterior muscle were colonized with C2C12 myoblasts in vitro. The recellularized scaffolds did not reach high cell densities comparable with the former systems but supported well cell anchorage and migration without any signs of cell regression.
