Abstract

患者衍生的肿瘤异种移植(PDX)和细胞衍生肿瘤异种移植(CDX)是临床前评估、药物指导和基础癌症研究的重要技术。传统宿主小鼠的一代 PDX 模型非常耗时,只适用于一小部分样本。近年来,斑马鱼PDX(zPDX)已成为一种独特的宿主系统,具有体积小、效率高的特点。在这里,我们描述了一种优化的方法,用于在zPDX模型中生成双荧光标记肿瘤异种移植模型,用于比较化疗评估。肿瘤细胞和成纤维细胞在不同的培养条件下从新鲜收获或冷冻的胰腺癌组织中丰富。两个细胞组都标有表达绿色或红色荧光蛋白的慢病毒,以及抗凋亡基因BCL2L1。转染细胞被预混合,并共同注入2dpf幼虫斑马鱼,然后在32°C的改性E3培养中繁殖。用化疗药物和/或BCL2L1抑制剂治疗异种移植模型,同时研究肿瘤细胞和成纤维细胞的毒性。总之,该协议允许研究人员快速生成具有异构肿瘤微环境的大量zPDX模型,并提供更长的观察窗口和更精确的定量评估药物候选者的效率。
