| Outline of Final Research Achievements |
It was reported that cyclic extension force change wounds to hypertrophic scar or keloid. Although there was no animal model which made appropriate condition under that cyclic extension force was applied to wounds on the animal body.
I have designed the machine which can apply cyclic extension force continuously to mice wounds. Using this machine, wounds on both lateral sides of mice were extended and released for three weeks. Then in experimental group, wounds grew histlogical condition of hypertrophic scar or keloid. In addition to, I found that inflammatory cells run to the scar site, and keratinocyte in epidermis tend to grow under cyclic extension force.
