[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。 ...

Adoptive Transfer of Myeloid-Derived Suppressor Cells and T Cells in a Prostate Cancer Model

[Abstract]  The adoptive transfer of immune cells for cancer, chronic infection, and autoimmunity is an emerging field that has shown promise in recent trials. The transgenic adenocarcinoma mouse prostate (TRAMP) is a classical mouse model of prostate cancer (PCa) and TRAMP cell lines were derived from a TRAMP mouse tumor. TRAMP-C2 is tumorigenic when (subcutaneously) s.c. grafted into syngeneic C57BL/6 host mice (Foster et al., 1997). This protocol will describe the adoptive transfer of purified CD11b+Gr1+ double positive (DP) myeloid-derived suppressor cells (MDSC) and CD3+ T cells in the TRAMP-C2 prostate cancer mouse model in order to establish the intrinsic functionality of these immune cells and to determine their role in tumorigenesis in vivo ... [摘要]  免疫细胞用于癌症,慢性感染和自身免疫的过继转移是一个新兴领域,其在最近的试验中显示出希望。 转基因腺癌小鼠前列腺(TRAMP)是前列腺癌(PCa)的经典小鼠模型,TRAMP细胞系衍生自TRAMP小鼠肿瘤。 当皮下注射时,TRAMP-C2是致瘤的。 移植到同基因C57BL/6宿主小鼠中(Foster等人,1997)。 该方案将描述纯化的CD11b +(Ad)双重阳性(DP)骨髓衍生的抑制细胞(MDSC)和CD3 + sup/+的过继转移。 T细胞在TRAMP-C2前列腺癌小鼠模型中的表达,以便建立这些免疫细胞的内在功能并且确定它们在体内的肿瘤发生中的作用(Yan等人)。 ,2014)。

[Abstract]  Adoptive transfer experiments of specific cell populations are widely used methods to assess the role of the injected population on an ongoing process. In the last years, new and unprecedented roles in the regulation of immune responses have been reported for neutrophils. The following protocol is to be used to isolate neutrophils from bone marrow and to inject them in an appropriate host to test the role of neutrophils during infection, inflammation or other pathological conditions. [摘要]  特定细胞群体的过继转移实验是广泛使用的方法来评估注射群体对正在进行的过程的作用。 在过去几年中,已经报道了中性粒细胞在免疫应答的调节中的新的和前所未有的作用。 以下方案用于从骨髓中分离嗜中性粒细胞,并将其注射在合适的宿主中,以在感染,炎症或其它病理状况期间测试嗜中性粒细胞的作用。
