实验转移和CTL过继转移免疫小鼠模型
Summary
一个实验性肺转移和CTL免疫小鼠模型的肿瘤细胞- T细胞相互作用分析<em>在体内</em>。
Abstract
实验转移小鼠模型是一个简单的，但有关生理转移模型。肿瘤细胞静脉注射（四）为小鼠尾静脉和殖民，从而在肺部，类似肿瘤细胞自发转移的最后步骤：在流通领域，外渗及远端器官的殖民化的生存。从治疗的观点来看，实验转移模型是最简单和理想的模式，自疗法的目标往往是：建立在远端器官的转移瘤的转移终点。在此模型中，肿瘤细胞注射四到小鼠尾静脉，并允许在肺部进行殖民和增长。然后注入肿瘤特异性CTL转移轴承鼠标第四。肺转移的数量和大小，可以控制被注入肿瘤细胞的数量和肿瘤生长的时间。因此，各个阶段的转移，从最小的转移到全身广泛转移，可为蓝本。肺转移，从而允许更容易直观地观察和定量分析与油墨的通货膨胀。
Protocol
1。实验转移小鼠模型前一天的肿瘤细胞的注射剂，种子之一T75容量瓶中，用高达1 × 10 7 CMS4了10 mL的RPMI培养基中含有10％的血清，以获得快速增长的肿瘤细胞中的细胞。过夜孵育在37 ° C。 在注射当天，去除培养基，用PBS冲洗细胞一次，然后用0.05％胰酶EDTA收获肿瘤细胞在37 ° C为5分钟。停止与10 mL的RPMI培养基中含有10％血清中反应。细胞转移到锥形管。 分拆为3分钟，…

Materials
Solutions:
India Ink Solution (17):
- Pour 150 ml of distilled water into a 250 ml flask.
- Add 4 drops ammonium hydroxide to the distilled water.
- Add 30 ml India Ink stock (i.e. Sanford Black Magic Waterproof Drawing Ink 4465 Item 44011) to the ammonia and water mixture.
- Top off with distilled water to a volume of 200 ml. Solution is ready for injection.
Fekete’s Solution (17):
Fekete’s solution is used to bleach India ink-inflated tumor-bearing lungs to distinguish white tumor nodules from the black background of normal tissues.
- Add 350ml 95% EtOH to 1L glass bottle.
- Add 150ml distilled water
- Add 50ml formaldehyde
- Add 25ml glacial acidic acid
