| Research Abstract |
1. From the clinicopathological observation of antibody-mediated rejection in living donor ABO-incompatible kidney transplantation and ischemia-reperfusion injury in deceased donor kidney transplantation, We had analyzed and evaluated the process of the microcirculation injury and microvascular endothelial-cell damage.
2. We had established the GFP(+) to (-) rat bone marrow transplantation model and evaluated the role of The bone marrow derived endothelial progenitor cells in the regeneration of the injured microvascular Cells in renal ischemia-reperfusion injury.
3. We have revealed that the bone marrow derived endothelial cells have migrated and recovered the injured endothelial cells in renal ischemia-reperfusion injury. It was approved not only by static immunohinstopathological-method but also by dynamic-direct observation by real-time phase contrast microscopy.
4. Our result have approved for the first time that the injured renal microvascular endothelial cells were restored by Bone-marrow derived cells and reconstructed functional microvasculature.
These result will be useful for the clinical renal preservation and regeneration therapy for antibody-mediated rejection in ABO-incompatible kidney transplantation and ischemia-reperfusion injury in deceased donor kidney transplantation.
