| Outline of Final Research Achievements |
In this study, we analyzed the specific gene expressed in fetal wound healing (FWH) in mouse cardiac fibroblast cells characterized by without scar formation. By using DNA microarray analysis, anti-fibrosis related genes including Has2, Tm, and Mmp genes, and morphogenesis related genes (Foxo, Hox, and Pax) highly expressed in FWH, whereas the expression of these genes down-regulated in adult wound healing (AWH) with scar formation. Down regulation of Pax gene expression are down regulated by methylation on histone H3 domain, whereas downregulation of other genes were induced by DNA methylation of each promoter region, respectively. Finally, we injected each gene into myocardial infarction tissue of adult mice. As the result, each gene did not induce FWH characterized perfect scarless reaction, suggesting alone administration of each gene was not effective, and cocktail therapy, the combination of multiple genes, are necessary of inducing of FWH.
