| Outline of Final Research Achievements |
A decrease in Tissue inhibitor of metalloprotease-2 (TIMP2) was observed in keloid-like tissues in a mouse persistent tensile loading model. In epidermal cells, smooth muscle actin (SMA) was expressed by tensile strength. Administration of basic fibroblast growth factor suppressed expression of SMA, but decreased expression of TIMP2 was observed. In other words, epidermal cells subjected to tensile strength expressed SMA to antagonize the force. Furthermore, it was suggested that fibroblasts produced collagen to obtain further strengthen.
