Abstract

To determine the potential of mesenchymal stem cells (MSC) for corneal epithelial regeneration . Bone marrow MSC (BM-MSC) and adipose tissue MSC were analyzed for corneal epithelial and mesenchymal markers, using limbal stem cells and corneal cells as controls. MSC with better potential were cultured with specific mediums for epithelial induction. Transepithelial electric resistance and wound healing assay with human corneal epithelial cells were performed. BM-MSC showed better potential, increased corneal markers, and higher transepithelial electric resistance values when induced with limbal epithelial culture medium. Induced BM-MSC promoted better wound healing of human corneal epithelial cells by paracrine secretion. BM-MSC has potential for corneal epithelial induction in a protocol compatible with human application.

摘要

为了确定间充质干细胞(MSC)在角膜上皮再生中的潜力。采用角膜缘干细胞和角膜细胞作为对照,分析骨髓间充质干细胞(BM-MSC)和脂肪组织 MSC 的角膜上皮和间充质标志物。用特定的上皮诱导培养基培养具有更好潜力的 MSC。用人角膜上皮细胞进行跨上皮电阻和伤口愈合试验。BM-MSC 具有更好的潜力,当用角膜缘上皮培养基诱导时,增加了角膜标志物和更高的跨上皮电阻值。诱导的 BM-MSC 通过旁分泌促进人角膜上皮细胞的更好伤口愈合。BM-MSC 具有在与人类应用兼容的方案中诱导角膜上皮的潜力。
