Abstract

Purpose

This study aimed to investigate the therapeutic potential of extracellular vesicles (EVs) derived from human amniotic epithelial cells (hAEC-EVs) for Dry Eye Disease (DED) treatment.

Methods

Highly purified EVs were isolated from the culture supernatants of hAECs, which obtained from term placenta and characterized. Proteomic contents were analyzed for assessing its biological function related to the therapeutic potentials for DED. Subsequently, we examined the therapeutic efficacy of hAEC-EVs on human corneal epithelial cells exposed to hyperosmotic stress and in an experimental DED mouse model induced by desiccation stress.

Results

Proteomic analysis of hAEC-EVs revealed proteins linked to cell proliferation and anti-inflammatory responses. We demonstrated efficient uptake of hAEC-EVs by ocular surface cells. Under DED conditions, EV treatment increased corneal epithelial cell proliferation and migration, and concurrently reducing inflammatory cytokines. In the DED mouse model, hAEC-EVs showed significant improvements in corneal staining score, tear secretion, corneal irregularity, and conjunctival goblet cell density. Additionally, hAEC-EVs exhibited a mitigating effect on ocular surface inflammation induced by desiccation.

Conclusions

These findings suggest that hAEC-EVs hold potential as a cell-free therapy for corneal epithelial defects and ocular surface diseases, presenting a promising treatment option for DED.

开发人羊膜上皮细胞衍生细胞外囊泡，作为干眼症的无细胞疗法。

目的：本研究旨在探讨从人羊膜上皮细胞（hAEC-EVs）中提取的细胞外囊泡（EVs）治疗干眼症（DED）的潜力。方法：从足月胎盘中获得的 hAECs 培养上清液中分离出高度纯化的 EVs，并对其进行了表征，分析了其蛋白质组含量，以评估其与 DED 治疗潜力相关的生物功能。随后，我们研究了 hAEC-EVs 对暴露于高渗透压下的人角膜上皮细胞和干燥应激诱导的实验性 DED 小鼠模型的治疗效果：hAEC-EVs的蛋白质组分析显示了与细胞增殖和抗炎反应相关的蛋白质。我们证明了眼表细胞对 hAEC-EVs 的高效吸收。在 DED 条件下，EV 处理增加了角膜上皮细胞的增殖和迁移，同时减少了炎症细胞因子。在 DED 小鼠模型中，hAEC-EVs 能显著改善角膜染色评分、泪液分泌、角膜不规则性和结膜上皮细胞密度。此外，hAEC-EVs 对干燥引起的眼表炎症也有缓解作用：这些研究结果表明，hAEC-EVs 具有作为角膜上皮缺陷和眼表疾病无细胞疗法的潜力，为 DED 的治疗提供了一种前景广阔的选择。

期刊介绍： The Ocular Surface, a quarterly, a peer-reviewed journal, is an authoritative resource that integrates and interprets major findings in diverse fields related to the ocular surface, including ophthalmology, optometry, genetics, molecular biology, pharmacology, immunology, infectious disease, and epidemiology. Its critical review articles cover the most current knowledge on medical and surgical management of ocular surface pathology, new understandings of ocular surface physiology, the meaning of recent discoveries on how the ocular surface responds to injury and disease, and updates on drug and device development. The journal also publishes select original research reports and articles describing cutting-edge techniques and technology in the field.
