项目摘要

Epithelial-mesenchymal transition (EMT) is a phenomenon in which injured epithelia acquire myofibroblastic properties, leading to progressive fibrosis. EMT was analyzed in renal epithelia, bile duct epithelia and follicular epithelia in renal fibrosis, peribiliary fibrosis and cutaneous fibrosis, respectively. The acquisition of myofibroblastic properties of incomplete renal regeneration in renal fibrosis was demonstrated; this EMT was inhibited by PGE2 and NGAL, but promoted by osteopontin. Since nephric blastema showed myofibroblastic properties, suggesting that renal EMT is a retroactive phenomenon towards renal blastema. Evident EMT was not shown in the bile duct epithelia in peribiliary fibrosis or follicular epithelia in cutaneous fibrosis. Myofibroblasts may be derived from the mesenchymal stem cells such as pericytes and bone-marrow stem cells. The present study gives a novel concept (EMT theory), which would open clues of possible therapies for intractable fibrosis.
上皮 - 间质转变(EMT)是一种现象,其中受伤的上皮获得肌纤维细胞特性,导致进行性纤维化。在肾上皮,胆管上皮和卵泡上皮中分析EMT分别在肾纤维化,细胞纤维纤维化和皮肤纤维化中分析。证明了肾纤维化中不完全肾脏再生的肌纤维细胞特性的获取。该EMT被PGE2和NGAL抑制,但由骨桥蛋白促进。 由于肾胚芽表现出肌成纤维细胞的特性,因此表明肾脏EMT是一种追溯现象,朝向肾脏胚芽。 在皮肤纤维化或皮肤纤维化中,胆管上皮上没有显示明显的EMT。肌纤维细胞可以源自间充质干细胞,例如周细胞和骨髓干细胞。本研究给出了一种新颖的概念(EMT理论),该概念将为可治尿纤维化的可能疗法开辟线索。
