| Outline of Final Research Achievements |
We developed novel mesenchymal stem cells from canine bone marrow and named the cells as bone marrow per-adipocyte cells（BM-PACs). BM-PACs attached to adipocytes in bone marrow and have superior potentials as multipotent cells compared with conventional canine bone marrow mesenchymal stem cells (BMMSCs). Additionally, BM-PACs showed higher expression of hepatocyte growth factor (HGF), which is known to have great healing effects on injured tissues, than BMMSCs. After locally injected into a mouse skin injury model, BM-PACs migrated toward the injured area and showed HGF expression. In addition, intravenously injected BM-PACs also migrated toward injured area and showed HGF expression. Thus, our results suggest that stem cell therapy using BM-PACs offer a healing effect through the supply of HGF to the injured site.
