年龄相关性黄斑变性(AMD)、色素性视网膜炎和其他RPE相关疾病是工业发达国家中成人不可逆视力丧失的最常见原因。RPE移植似乎是一种有前途的治疗方法,因为它可以取代功能失调的RPE,恢复其功能,从而恢复视力。在这里,我们描述了一种将培养的RPE单层在支架上移植到兔视网膜下腔(SRS)的方法。玻璃体切除术后,使用定制的注射器将异种移植物输送到SRS中,该注射器由20号金属喷嘴和聚四氟乙烯(PTFE)涂层柱塞组成。目前的技术在6年内的150多例家兔手术中得到了发展。术后随访可以使用非侵入性和重复性体内成像获得,例如谱域光学相干断层扫描(SD-OCT),然后进行灌注固定组织学检查。该方法步骤明确,易学,成功率高。兔被认为是用于临床转化的临床前研究的大眼睛动物模型。在这种情况下,兔子是一个具有成本效益的,也许是方便的替代其他大眼睛动物模型。
Age related macular degeneration (AMD), retinitis pigmentosa, and other RPE related diseases are the most common causes for irreversible loss of vision in adults in industrially developed countries. RPE transplantation appears to be a promising therapy, as it may replace dysfunctional RPE, restore its function, and thereby vision. Here we describe a method for transplanting a cultured RPE monolayer on a scaffold into the subretinal space (SRS) of rabbits. After vitrectomy xenotransplants were delivered into the SRS using a custom made shooter consisting of a 20-gauge metallic nozzle with a polytetrafluoroethylene (PTFE) coated plunger. The current technique evolved in over 150 rabbit surgeries over 6 years. Post-operative follow-up can be obtained using non-invasive and repetitive in vivo imaging such as spectral domain optical coherence tomography (SD-OCT) followed by perfusion-fixed histology. The method has well-defined steps for easy learning and high success rate. Rabbits are considered a large eye animal model useful in preclinical studies for clinical translation. In this context rabbits are a cost-efficient and perhaps convenient alternative to other large eye animal models.
