| Outline of Final Research Achievements |
Scar lesions found in human are scarcely developed in murine. We created a novel model of scar forming wound by resecting a small portion of the rectus abdominis in mice, where muscular tensile force is physically loaded. In 3 weeks after the resection, the lesions with collagen-rich granulations were develop accompanied with multiple nodular lesions that is similar to the hypertrophic scars in human. In conclusion, this novel technique is the first established for the development of hypertrophic scars under a physiological condition in mice. We believe that this model is quite useful to investigate of new drugs for the patients with scar lesions in future.

本研究により、生理学的環境下で瘢痕病変を形成できる動物(マウス)モデルを世界で初めて創出できた。このモデルにより、今まで明らかにされていなかった瘢痕病変が主体となる肥厚性瘢痕やケロイドの病態解明につながることが期待できる。また、本モデルを使用することで、治療法の開発などにも活用でき、瘢痕性病変に悩む患者に対し新規治療法の開発につながり、社会的意義も大きい。
