Biomaterials and Tissue Engineering
The programme is focused on advanced trends in medicine aimed at usage of sophisticated tissue prostheses systems composed of synthetic materials combined with specific biologically active compounds and cells for regeneration and replacement of diseased tissues and organs or for controlled drug and gene delivery targeted to specific tissues and cells in diseased organism. The programme feasibility is guaranteed by the close collaboration of “synthesis” teams concerned with the development and synthesis of artificial carriers for cells, therapeutics and diagnostics, and “biomedicine” teams concerned with applications of cells, including stem cells, development of bioartificial grafts for tissue engineering, and testing therapeutic and diagnostic systems. The basic common activities of the “synthesis” teams consisting in synthesis of polymer materials with attached biologically active components will be based in general on investigation and testing interactions of cells and tissues with the biomaterials directed to specific medical applications.
The overall aim of the applied research within this programme is to develop technologies for preparation of the intended products and to standardize this preparation so that it is possible to transfer these technologies over to clinical practice. Planned outputs include: bioartificial blood vessel, valve, bone, and cartilage grafts, scaffolds for therapy of spinal cord lesions, targeted drug, gene, and diagnostics delivery systems for therapy and diagnostics of cancer and cardiovascular diseases, biosensors and protein chips, and affinity carriers for separation and purification of biological fluids and suspensions.
