Outline of Final Research Achievements

Wound healing at the site of peripheral tissue signals to the bone marrow followed by regulating the function by each other. Even the quality of the thrombus is under the function of bone marrow. The most important work in this study is to publish the paper which showed dynamics of intra-platelet VEGF-A from cancer to the later phase of liver regeneration after partial hepatectomy in humans. The amount of intra-platelet VEGF-A changed dramatically under the course of liver regeneration which means the pivotal role of bone marrow funciton to modulete the platelet quality contributing to the wound healing. In this study, we clearly showed the cross-talk between peripheral event and bone marow response in case of organ regeneration. Furthermore, we showed two distinct phases of liver regeneration after partial hepatectomy, an early inductive phase with rapid proliferation of hepatocytes followed by an angiogenic phase distinguished by the expansion of non-parenchymal compartment.
