While the mouse retina has emerged as an important genetic model for inherited retinal disease, the mouse vitreous remains to be explored. The vitreous is a highly aqueous extracellular matrix overlying the retina where intraocular as well as extraocular proteins accumulate during disease.(1-3) Abnormal interactions between vitreous and retina underlie several diseases such as retinal detachment, proliferative diabetic retinopathy, uveitis, and proliferative vitreoretinopathy.(1,4) The relative mouse vitreous volume is significantly smaller than the human vitreous (Figure 1), since the mouse lens occupies nearly 75% of its eye.(5) This has made biochemical studies of mouse vitreous challenging. In this video article, we present a technique to dissect and isolate the mouse vitreous from the retina, which will allow use of transgenic mouse models to more clearly define the role of this extracellular matrix in the development of vitreoretinal diseases.
虽然小鼠视网膜已成为遗传性视网膜疾病的重要遗传模型,但小鼠玻璃体仍有待探索。玻璃体是覆盖在视网膜上的一种高度含水的细胞外基质,在疾病过程中眼内和眼外蛋白质会在其中积聚。(1 - 3)玻璃体与视网膜之间的异常相互作用是几种疾病的基础,如视网膜脱离、增殖性糖尿病视网膜病变、葡萄膜炎和增殖性玻璃体视网膜病变。(1,4)相对而言,小鼠玻璃体体积明显小于人类玻璃体(图1),因为小鼠晶状体占据了其眼睛近75%的空间。(5)这使得对小鼠玻璃体进行生化研究具有挑战性。在这篇视频文章中,我们展示了一种从小鼠视网膜中解剖和分离玻璃体的技术,这将有助于利用转基因小鼠模型更清楚地确定这种细胞外基质在玻璃体视网膜疾病发展中的作用。
