optic nerve transection: a model of adult neuron apoptosis in the central nervous system

视网膜神经节细胞（RGC的）是中枢神经系统的神经元，输出的视觉信息从视网膜到大脑，通过视神经。视神经眼轨道内可以访问，并完全切断（axotomized），切割研资局在整个人口的轴突。视神经横断重现模型在1-4成人中枢神经系统的细胞凋亡的神经细胞死亡。这种模式是特别有吸引力，因为眼睛的玻璃体腔行为作为药物输送到视网膜的胶囊，允许通过人工注射的实验操作。通过玻璃体液体化学品的扩散，确保他们的行为后，整个研资局人口。此外，视网膜神经节细胞可以选择性地转用短干扰RNA（siRNAs）的质粒或病毒载体的视神经5-7或注入自己的目标，上丘8向量的切端。这使研究人员能够学习所需的神经元群的细胞凋亡的机制，没有其他旁观者神经元或神经胶质细胞周围的混杂影响。另外一个好处是与细胞的存活，可在伤后量化的易用性和准确性。视网膜是一个平面，分层组织和RGC的是在最里层，神经节细胞层的本地化。随着时间的推移，可跟踪的视网膜神经节细胞的生存，申请时间干切断视神经切开结束了荧光示踪（3％荧光金），或上丘（研资局的目标）前一周注入示踪剂干切断。示踪逆行运输，标签研资局在整个人口。由于神经节细胞层是单层（一个细胞厚），研资局的密度可量化的扁平式的组织中，无体视需要。视神经横断导致的90％受伤的视网膜神经节细胞的凋亡，14天以内 postaxotomy 9-11。研资局凋亡有一个特点的时间进程，使细胞死亡是推迟3-4天postaxotomy后，这些细胞迅速退化。这提供了一个针对在细胞凋亡有关的途径的实验操作的时间窗口。
