title: Cell migration between graft and host--an analysis with monoclonal antibodies after allogeneic rat kidney transplantation.
abstract: In order to analyse migration patterns of donor MHC class II cells out of transplanted kidney and accumulation of host cells within the graft, immunomorphological studies were performed using monoclonal antibodies in rat allogeneic kidney transplantation model. To answer the question of how many donor cells migrate out of the renal cortex MRC 0 x 3 monoclonal antibody (MoAb) against LEW MHC class II antigens was used. In the grafts explanted after 4,24 48 and 73 h, a slow reduction of donor class II cells was observed and some areas in cortex showed only very few, if any, donor cells. At the same time, starting from day 2 after transplantation accumulation of donor cells was found in perivascular spaces. Spleen sections stained at 24, 48, 72 and 96 h after transplantation revealed donor cells present in recipient's spleen. They were detected up to day 3 after surgery. Their numbers, however, decreased after day 2. After 2 and 3 days, accumulations of recipient's cells between tubules were detected. It was found that many cells in infiltrations were stained with anti-T lymphocyte MoAb. Expression of class II antigen on rat kidney cells increases significantly from the day 4 after transplantation.
