[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。 ...

[Abstract]  CD34 is a glycosylated cell surface protein and represents a well-known marker for primitive progenitor cells in various organs, especially cord blood, bone marrow and fetal liver. CD34+ progenitor cells are suitable for a series of studies, e.g. cell differentiation, transplantation as well as construction of humanized mouse models. Here, we describe a method to isolate CD34+ cells from the human cord blood and fetal liver.
[摘要]  CD34是糖基化的细胞表面蛋白,并且代表了在各种器官,特别是脐带血,骨髓和胎儿肝脏中的原始祖细胞的公知标记。 CD34 +祖细胞适合于一系列研究,例如细胞分化,移植以及人源化小鼠模型的构建。 在这里,我们描述了一种从人脐带血和胎儿肝脏中分离CD34 - sup + +细胞的方法。
