In this interdisciplinary project, adipose tissue-derived stem cells (ASCs) will be obtained by liposuction from the fat tissue of patients. Optimal conditions of the liposuction (particularly local anesthesia, negative pressure) will be elaborated in order to obtain the ASCs in high numbers and viability. ASCs will be then differentiated towards osteoblasts, vascular smooth muscle cells, vascular endothelial cells and keratinocytes by appropriate cell culture conditions, namely (i) a cell carrier with suitable physicochemical properties, such as rigidity or deformability, wettability, charge and conductivity, roughness and morphology, surface chemical structure, 2D or 3D structure, (ii) composition of cell culture media, (iii) mechanical stimulation in dynamic bioreactors and (iv) electrical stimulation. The differentiated ASCs will be used for construction of hybrid replacements of the bone tissue, blood vessels and skin. These replacements will contain a material carrier optimal for a given application and a cell component, and will be promising for future clinical applications.
