视网膜血管疾病如早产儿视网膜病变、糖尿病视网膜病变和视网膜静脉阻塞等以异常增生的视网膜新生血管为主要病理表现。骨髓间充质干细胞来源外泌体通过旁分泌作用传递生物活性分子介导细胞间的物质与信息交换。其中,miRNA等内容物在传递信息中起关键作用,可调控缺血缺氧环境下内皮细胞的增殖、管腔形成和新生血管的形成。并且能够通过血视网膜屏障而不引起免疫、炎症反应,在眼科疾病治疗中极具潜力。本文总结骨髓间充质干细胞衍生外泌体中miRNA在视网膜新生血管形成中的作用和可能的作用机制,以期为外泌体在眼科疾病诊治中的应用拓宽新思路。

[Abstract]
Retinal vascular diseases such as retinopathy of prematurity, diabetic retinopathy, and retinal vein occlusion, and other retinal vascular diseases, with abnormal proliferation of retinal neovascularization as the main pathological manifestation. Exosomes derived from bone marrow mesenchymal stem cells transmit biologically active molecules through paracrine action to mediate the exchange of materials and information between cells. Among them, miRNA and other contents play key roles in transmitting information to regulate the proliferation of endothelial cells, the formation of the lumen, and new blood vessels in an ischemic and hypoxic environment. And it can cross the blood-retinal barrier without causing immune and inflammatory reactions and has great potential in the treatment of ophthalmic diseases. This article summarizes the role and possible mechanism of miRNA in bone marrow mesenchymal stem cell-derived exosomes in retinal neovascularization, with a view to broadening new ideas for the application of exosomes in the diagnosis and treatment of ophthalmic diseases.
