In vivo Efficacy Studies in Cell Line and Patient-derived Xenograft Mouse Models

[Abstract]  In vivo xenograft models derived from human cancer cells have been a gold standard for evaluating the genetic drivers of cancer and are valuable preclinical models for evaluating the efficacy of cancer therapeutics. Recently, patient-derived tumorgrafts from multiple tumor types have been developed and shown to more accurately recapitulate the molecular and histological heterogeneity of cancer. Here we detail the procedures for developing patient-derived xenograft models from breast cancer tissue, cell-based xenograft models, serial tumor transplantation, tumor measurement, and drug treatment. [摘要]  衍生自人类癌细胞的体内异种移植模型已经成为评估癌症遗传学驱动因素的黄金标准,并且是用于评估癌症治疗药物功效的有价值的临床前模型。最近,已经开发了来自多种肿瘤类型的患者衍生的移植物,并且显示出更准确地概括了癌症的分子和组织学异质性。在这里,我们详细介绍了从乳腺癌组织,基于细胞的异种移植模型,连续肿瘤移植,肿瘤测量和药物治疗开发患者衍生异种移植模型的程序。

背景 异种移植模型已经成为研究癌症基因驱动因素和确定癌症治疗药物的潜在功效的有力方法。发现T细胞缺乏的无胸腺裸鼠(nu / nu)小鼠和T细胞和B细胞缺陷型严重联合免疫缺陷(scid / scid)小鼠(Flanagan, 1966; Bosma和Carroll,1991)。由于这些发现,其他免疫受损的小鼠模型已经变得可用,包括重组激活基因2(Rag2)敲除小鼠,非肥胖(NOD) - 小鼠和NOD-scid < il2rgamma(null)小鼠(也称为nsg小鼠)(shinkai等人,1992;="" prochazka等人,1992;="">
&nbsp;在开发包括注射或植入部位的异种移植模型时,应考虑几个选项。由于生长测量和成像的肿瘤可及性,皮下异种移植物通常用于体内研究;然而,该模型的显着限制是大多数癌细胞缺乏正常的基质微环境。原位异种移植物提供互补的基质微环境;然而,根据原位点,包括更复杂的外科手术,测量肿瘤生长或反应的难度以及啮齿动物基质的限制(Talmadge等人,2007),该途径也存在缺点。许多癌症研究尤其是乳腺癌研究中广泛应用原位异种移植物。注入乳腺脂肪垫是一个相对简单的程序,允许乳腺癌细胞的可见和可测量的生长。尽管乳腺脂肪垫为乳腺癌细胞提供了互补的组织部位,但重要的是注意到人和啮齿动物乳腺基质和激素环境之间存在明显差异。 ...

Mouse Mammary Intraductal (MIND) Method for Transplantation of Patient Derived Primary DCIS Cells and Cell Lines

[Abstract]  The MIND method involves intraductal injection of patient derived ductal carcinoma in situ (DCIS) cells and DCIS cell lines (MCF10DCIS.COM and SUM225) inside the mouse mammary ducts [Video 1 and Figure 1 in Behbod et al. (2009)]. This method mimics the normal environment of DCIS and facilitates study of the natural progression of human DCIS, i.e., their initial growth as carcinoma in situ within the ducts, followed by invasion into the stroma through the myoepithelial cell layer and basement membrane (Behbod et al., 2009; Valdez et al., 2011). In order to demonstrate that transplantation procedure is successful, the transplanted mammary glands may be excised as early as two weeks following intraductal injection of cells followed by Hematoxylin ... [摘要]  MIND方法涉及管内注射患者来源的导管原位(DCIS)细胞和DCIS细胞系(MCF10DCIS.COM和SUM225)(在小鼠乳腺导管内)[Video 1和FIG 1 in Behbod et al。 >(2009)]。该方法模拟DCIS的正常环境,并且有助于研究人DCIS的自然进展,即它们在导管内原位癌的初始生长,随后是侵入通过肌上皮细胞层和基底膜的基质(Behbod等人,2009; Valdez等人,2011)。为了证明移植手术是成功的,可以早在导管内注射细胞后两周,随后使用人特异性细胞角蛋白5和/或19的苏木精和曙红(H&E)染色和/或免疫荧光染色,切除移植的乳腺[请参见Behbod等人(2009)中的图2-4]。此外,在管内注射后立即在小鼠乳腺导管内存在台盼蓝是注射成功的最佳指示(视频1从4:33秒开始)。
