Biophysical methods for quality evaluation of decellularized and recellularized tissue-engineered constructs of organs and tissues.

Tissue engineering is rapidly growing now and can become a promising alternative to transplantation of organs and tissues, as it is devoid of major shortcomings of transplantology, such as acute shortage, complexity of selection, delivery and storage of donor material, lifelong immunosuppressive therapy. One of the most widely known methods of obtaining biological scaffolds for the subsequent creation of tissue-engineered constructs of organs and tissues is decellularization. The evaluation of the quality of the obtained scaffolds, based on the study of the viability of cell structures in decellularized and recellularized matrices, is one of the priorities of modern regenerative medicine worldwide.
