H: r\)mjeir oveI\NRPoifbDCCAAR%IhI4R30. .doc-I M/)2/2014 -61 The present inventors revealed the following for the first time in the world: 1) a large amount of bone marrow-derived cells are mobilized to grafted skin; 2) the mobilized bone marrow-derived cells are differentiated into any of dermal fibroblasts, adipocytes, muscle cells, vascular endothelial cells, and epidermal keratinocytes in the grafted skin, and the mobilized bone marrow-derived cells include bone marrow-derived mesenchymal stem cells; 3) the factors which mobilize bone marrow-derived mesenchymal stem cells from peripheral blood to the grafted skin are HMGB1, HMGB2, and HMGB3 released from the necrosed tissue of recipient skin; 4) purified HMGB1, HMGB2, and HMGB3 promote the migration of mesenchymal stem cells isolated and cultured from bone marrow; 5) activators containing HMGB1 which allows the migration of bone marrow mesenchymal stem cells can be conveniently purified from several organ extracts including skin, brain, and heart; 6) activators which allow the migration of bone marrow mesenchymal stem cells can be conveniently extracted from cultured cells; and 7) a heparin-column purified fraction of skin extract mobilizes a large amount of bone marrow-derived cells in case of brain injury. |
