德国Tübingen医院眼科中心的Kunzmann BC近日在Cell Tissue Bank杂志上发表了他们近期的一项工作,他们建立了与人角膜相当的猪角膜的器官培养模型。

人的角膜因为珍贵,通常不用于研究,它们仅用于移植。同时,体外培养的人类内皮细胞的科学研究可能由于不可避免的去分化而产生误导性的结果。因此,研究与人角膜相当的猪角膜的器官培养模型是非常必要的,这种器官模型可以用于研究人内皮细胞死亡率与培养的人类角膜之间的差别。

在无菌条件下收取新鲜的猪眼,获得角膜巩膜组织。角膜组织和所谓的"分离角膜组织"(新制备方法)共培养15天。在第1、8和15天通过光学显微镜观察内皮细胞的细胞形态。在第15天,用台盼蓝和茜素红S染色。随机进行拍照,按照无倾向性的方式进行评估。分析角膜内皮细胞的形态和每平方毫米的内皮细胞数。

经过分析发现,培养15天后,内皮细胞层在角膜组织和分离的角膜组织中存在。相比角膜组织培养,分离角膜组织培养的茜素红S染色区域和多边形如玫瑰花形的存在显着减少。相比分离的角膜组织,角膜组织的内皮细胞损失明显增加。分离的角膜组织大约是417±138/179细胞/平方毫米(中位数±25%/75%分位数),约占10.2%;角膜组织大约是575±25/250细胞/平方毫米(中位数±25%/ 75%分位数),约占14.8%。使用新方法分离的角膜组织,和猪角膜共培养2周后,细胞死亡率与角膜组中相应的人体组织的细胞死亡率相当。而这个过程不需要向培养基中加入去溶胀的添加剂。

因此作者认为,这是一种简单可靠的方法模型,可以用于天然化合物对角膜内皮细胞的干预研究。
