Transplantation of Cultured Mononuclear Fraction of Bone Marrow Cells in the Treatment of Heymann Nephritis in Rats.

In an experiment on Wistar rats, a Heymann's active nephritis model was reproduced. After the chronic course of the disease was confirmed, we compared the effectiveness of single systemic and local transplantation of allogeneic cultured stromal cells of the mononuclear fraction of the bone marrow. Both methods of cell therapy reduced clinical manifestations of active Heymann's nephritis: proteinuria decreased and glomerular filtration rate increased 30 days after cell administration. At the histological level, signs of the inflammatory process manifested in an increase in the number of CD68⁺ cells. Thus, in the case of autoimmune glomerulonephritis, two transplantation methods provide a comparable level of correction of functional disorders in Heymann's active nephritis model.
