Outline of Final Research Achievements |
In mammalian fetuses, up to a certain point, skin wounds regenerate quickly and completely without scarring. The epidermal factor is not cell migration but formation of actin cables and contraction of epidermal tissue, which results in wound closure without changing the positional value of epidermal cells, but the mechanism of dermal fibroblast migration for complete regeneration of mouse embryonic skin has not been reported. In this study, we observed the wound healing process in mice E13 to E15 and observed how altering the migration of dermal fibroblasts affects skin regeneration.

Academic Significance and Societal Importance of the Research Achievements |
瘢痕の線維化を抑制させようという様々な試みは、肺線維症、肝硬変など多くの線維 性疾患を解決する糸口になり、皮膚のみならず非常に大切な分野である。線維化の原因は、最終的にはコラーゲンを産生する真皮の線維芽細胞にある。一方で、近年線維芽細胞の多様性が報告されているが、胎生期の真皮の線維芽細胞は、線維化を起こす特徴が少ない、この特徴を知りその動態を変化させて瘢痕の有無を調べることは、他臓器の線維化のメカニズムを調べるうえでも必要な研究である。
