quantitative analysis of cancer metastasis using an avian embryo model

在转移的癌细胞从原发肿瘤的传播，侵入到周围组织，并扩散到远处器官。转移是一个复杂的过程，可能涉及到许多的组织类型，变量跨度的时间段，经常发生深刻的内部器官，使其难以进行调查和量化。此外，转移过程中的疗效的影响使其难以评估单一的肿瘤细胞行为方面的贡献，在转移级联的多个步骤。因此，经常进行转移检测在实验动物提供了一定的现实背景下，在其中学习转移。不幸的是，这些模型进一步复杂，其复杂的生理。鸡胚是一个独特的体内模型，克服了很多的局限性研究转移，由于绒毛尿囊膜（CAM），一个良好的血管多余的胚胎组织位于下面的蛋壳，是接受了肿瘤细胞的xenografting无障碍（图1）。此外，由于鸡胚是自然免疫缺陷，CAM容易支持正常和肿瘤组织植入。最重要的是，禽流感的CAM成功地支持大多数癌症细胞的特点，包括生长，侵袭，血管生成，和微环境重塑。这使得模型特别有用的调查导致癌转移的途径，并预测转移性癌的新的潜在疗法的反应。物种的具体铝PCR检测细胞播散，使人们有可能定量评估，是殖民统治只有25细胞的转移器官。使用人类的表皮细胞株（HEp3），我们使用这个模型来分析癌细胞的自发转移到远处器官，包括鸡胚肝脏和肺。此外，我们使用ALU - PCR协议表明，作为一种工具来分析和定量转移的单个元素的血管内，逮捕，外渗，和殖民的灵敏度和可重复性的检测。
