adenoviral gene therapy for diabetic keratopathy: effects on wound healing and stem cell marker expression in human organ-cultured corneas and limbal epithelial cells

该协议的目的是描述分子改变在人类糖尿病性角膜并展示如何能够通过在器官培养的角膜的腺病毒基因治疗得到缓解。糖尿病角膜病是角膜神经和上皮伤口愈合的频繁异常糖尿病的并发症。我们也记录在人类糖尿病几个角膜上皮推测干细胞标记显著改变的表达。为了减轻这些变化，腺病毒的基因治疗用的c-met原癌基因表达的上调和/或蛋白酶基质金属蛋白酶10（MMP-10）和组织蛋白酶F.本疗法的下调成功实施糖尿病角膜伤口加速愈合即使只有角膜缘干细胞室转导。最好的结果是用联合治疗获得。对于标准化的干细胞可能病人移植的例子也提出了优化*的在使用聚阳离子促进干细胞富集的文化基因转导。这种方法不仅可用于选定的基因而且对角膜上皮创伤愈合的其他介质是有用的和干细胞功能。

我们以前表明，在角膜器官培养，糖尿病标记物（ 例如 ，基底膜蛋白和整联α3β1）的正常和糖尿病角膜之间和伤口愈合中的表达的差异将被保留。此培养系统进行基因治疗，旨在正常化糖尿病改变的标记物，c-Met的MMP-10的水平，以及组织蛋白酶F. 当整个角膜上皮用对AV-CMET或AV-shRNA的对MMP-10或组织蛋白酶F（单独或组合）?...

Adenoviral Gene Therapy for Diabetic Keratopathy: Effects on Wound Healing and Stem Cell Marker Expression in Human Organ-cultured Corneas and Limbal Epithelial Cells

An example of adenoviral gene therapy in the human diabetic organ-cultured corneas is presented towards the normalization of delayed wound healing and markedly reduced epithelial stem cell marker expression in these corneas. It also describes the optimization of this process in stem cell-enriched limbal epithelial cultures.
