FIELD: medicine. ^ SUBSTANCE: inventions relate to medicine, namely to cell transplantology, and deal with method and transplant for treatment of liver failure. For this purpose autologous progenitor cells of bone marrow are isolated and cultivated in vitro. Also realised is sampling of autologous liver cells. After that, immobilisation of autologous liver cells and progenitor cells of bone marrow on carrier - biodegradable biocompatible three-dimensional matrix is performed. After that, transplantation of carrier with cells is performed by its introduction into mesentery of small intestine. Transplant includes biodegradable biocompatible three-dimensional porous matrix with pore size 2-500 mcm and total porosity 50-97%, ensuring total concentration of liver cells and progenitor bone marrow cells 2ù106-15ù106 cells per 1 cm3 of matrix and ratio of progenitor bone marrow cells to liver cells from 1:1 to 1:4. Total volume of matrix constitutes not less than 0.05 cm3, its smallest linear size being not less than 0.2 mm. ^ EFFECT: inventions make it possible to improve results of liver failure treatment due to prolongation of terms of hepatocyte survival and activisation of their proliferation, creation of conditions for growing of vessels into creates carcass, diffusion of nutrients, oxygen and factors of tissue differentiation, make it possible to avoid application of immunosuppressive therapy. ^ 6 cl, 6 dwg |
