    The aim of this study was to elucidate the metastatic mechanism of squamous cell carcinoma (SCC) arising in patients with dystrophic epidermolysis bullosa (DEB) caused by mutations in type 7 collagen (COL7) gene. DEB patient model keratinocytes with a comprehensive gene-editing did not develop metastasis when transplanted subcutaneously in mice, but the subcutaneous tumors of DEB patient model showed an overall irregular structure, surrounding fibrosis, and hypervascularization compared to subcutaneous tumors of normal keratinocytes. These results suggest that subcutaneous tumors in DEB patient model induce changes in the surrounding tissue environment via abnormal construction of the basement membrane, and that these changes may contribute to the metastatic mechanism of SCC in DEB patients.

  • Establishment of cicatricial alopecia animal models

    Cicatricial alopecia is a type of hair loss characterized by loss of hair follicles and surrounding fibrosis. The aim of this study was to elucidate the mechanism of cicatricial alopecia by analyzing the hair follicles in the blistered skin of mice in detail. A major finding was a delay in hair follicle development/cycling at the re-epithelialized wounds after blistering. At the same time, infiltration of inflammatory cells was poor at the site where several layers of epithelization were completed, and there was no difference compared to the intact site. Taken together, these results indicate that the early stage of cicatricial alopecia involves less inflammation, with the proliferation of epithelial cells required for hair follicle growth directed toward re-epithelialization.

  • Elucidating roles of plasmin in blister formation of bullous pemphigoid

    Bullous pemphigoid (BP) is an autoimmune blistering disease. The aim of this study is to address the pathogenic roles of plasmin, a protease present in blister fluids of BP, which is known to cleave COL17. We first identified cleavage sites of COL17 by plasmin, and based on this data, cleavage site-specific antibodies were generated. The antibodies revealed that COL17 is actually cleaved by plasmin in lesional skin of certain numbers of BP patients.

  • Investigation of hematopoietic stem cell transplantation for epidermolysis bullosa

    Epidermolysis bullosa (EB) is a group of genodermatoses that cause blister formations from the congenital abnormality of anchor proteins between the epidermis and the dermis. There have been several strategies for the treatment of EB, and so far, cell therapies are the most promising approach because of the potential of systemic effects. We have proved that stem cell therapies, including bone marrow transplantation, hematopoietic stem cell transplantation, can ameliorate the phenotype and survival prognosis in the junctional EB model mice that lack type XVII collagen (Col17). In this study we explore more efficient approaches of stem cell therapies for EB, including intramedullary transplantation, mesenchymal stromal/stem cell infusion, and investigate factors in association with transdifferentiation from bone marrow-derived stem cells into keratinocytes.

  • Objective Evaluation Method of Genetic Treatment for Epidermolysis bullosa

    non-Herlitz接合部型表皮水疱症レスキューマウスを詳細に解析し、遺伝子導入治療の客観的評価法を検討した。レスキューマウスに生じる臨床効果の差異は超微細構造学的構造変化と蛋白発現によっても確認することができた。これらの差異が生じる要因として遺伝子導入状態の違いを確認することができたが、この違いを明らかにするためには導入されたgenomic DNAを確認するだけでは不十分であった。臨床効果を分岐する遺伝子導入状態の分岐点を明らかにするためにはrealtime PCRによるmRNAの定量、Fluorescence in-situ Hybridization法による遺伝子導入部位の確認が必要である。
