胰腺癌的切除矫形小鼠模型很重要，因为它允许检测辅助剂和新辅助治疗。这在胰腺癌中尤为重要，因为手术仍然是最有效的治疗方法，但与复发的高风险有关。本文描述了一种可以可靠地产生胰腺癌的方法，这种方法通过切除可以治愈，复制了需要新辅助/辅助疗法的临床场景。
对现有方法的意义 尽管辅助疗法和新辅助疗法在胰腺癌中的重要性，但文献中很?...

胰腺管腺癌（胰腺癌[PC]）与不良预后1有关。手术切除术仍然是PC唯一潜在的治疗方法，对于患有早期疾病的患者应予以考虑。不幸的是，即使R0切除（即切除边缘没有肿瘤），复发率（局部或从未被发现的转移性疾病）是高2，3。因此，全身辅助疗法在几乎所有接受切除4的患者中都显示。此外，虽然新辅助疗法现在只推荐给边缘可切除的癌症，其适应症正在扩大，使其常规使用是许多临床研究的重点5，6，7，8。为了开发涉及切除的 PC 的新疗法，这些方法需要首先在临床前模型中进行评估，以准确回顾临床设置。
矫型小鼠型号的PC已经经常用于测试药物治疗9，10。其中许多是由单独注射癌细胞到小鼠胰腺产生的，导致肿瘤缺乏PC特有的突出的频闪。最近，联合注射正交模型，如我们最初通过注射人类PC和人类胰腺恒星细胞的混合物（PSC，PC中胶原体频闪的主要生产者）而开发的模型，已经进入常规使用11，12。这种癌症和频闪细胞的联合注射产生的肿瘤既表现出癌症元素和PC的特有的频闪（去塑性）成分，（二）增强癌细胞增殖和转移11。因此，这个模型非常类似于人类PC。虽然一些矫形PC的切除模型被描述为13，14，15，16，但没有一个反映临床现实的胰腺切除在人类的准确如这个模型，因此一直不尽如人意的测试辅助剂或新辅助治疗。
演示的小鼠模型的目的是演示如何：（i） 成功植入正交胰腺癌，同时最大限度地减少无意的腹内传播和 （ii） 随后完全切除癌症。本文强调了该技术的技巧和潜在陷阱。

an orthotopic resectional mouse model of pancreatic cancer

在考虑接受胰腺癌手术（PC）的患者中，缺乏令人满意的动物模型来研究辅助疗法和/或新辅助疗法。为了解决这一缺陷，我们描述了一个涉及 PC 正交植入的鼠标模型，然后是切除胰腺切除术和切除术。该模型已被证明是安全的和适当的灵活，用于研究各种治疗方法的辅助和新辅助设置。
在这个模型中，胰腺肿瘤首先通过将人类胰腺癌细胞（路西法酶标记的AsPC-1）和人类癌症相关胰腺板状细胞的混合物植入Balb/c水生裸鼠的离散胰腺而生成。三周后，癌症通过切除术、切除胰腺切除术和切除术进行切除。在这个模型中，生物发光成像可用于跟踪癌症发展的进展和切除/治疗的影响。切除后，可给予辅助治疗。或者，在切除前可以进行新辅助治疗。
介绍了来自45只小鼠的代表数据。所有小鼠都成功地进行了胰腺切除术/切除术，没有血吸虫病问题。在 43 （96%） 中实现了大于 5 mm 的宏观近胰腺边缘小 鼠。胰腺切除技术成功率为100%，早期死亡率和发病率为0%。在切除后的一周内，没有一只动物死亡。
总之，我们描述了一个强大和可重复的技术，用于模拟临床场景的小鼠胰腺癌手术切除模型。该模型可能有助于测试辅助剂和新辅助治疗。

连续有59只老鼠接受了植入手术。总泄漏发生在八 （14%）小 鼠。注射时的泄漏程度估计如下协议部分所述。三周后，为了让这些植入的肿瘤生长，在切除前进行了预切除生物发光成像，排除了患有严重转移性疾病的小鼠。45 （76%）老鼠接受了手术切除手术。
所有 45 （100%）小鼠成功地进行了切除胰腺切除术/切除术，没有出血问题。在 43 （96%） 中实现了大于 5 mm 的宏观近胰?...
