Outline of Final Research Achievements |
The hypertrophic scars (HS) and keloids were analyzed using a new electron microscope FIB / SEM to investigate whether it is possible to distinguish the difference between three dimensional structures. The samples were obtained from 4 tissue types of ①normal skin, ② mature scar, ③ hypertrophic scar and ④ keloid. The statistical analysis was conducted on the significant differences of contact between both fibroblasts (Fb) and macrophage (Mφ) cells, and the significant differences of contact mode in these four tissue type. Regarding the presence or absence of contact, there was a significant difference between ①②③ and ④, and there was a significant difference between ①② and ③ contact form. Therefore, there was a distinct difference in tissue construction between hypertrophic scar and keloid under the electron microscope, and it was thought that it is possible to distinguish between them using this technique.
