肿瘤分泌的胞外囊 (EVs) 可以改变局部和远端间充质细胞的生理, 从而产生肿瘤支持的环境。在这里, 我们描述的一代骨肉瘤的前体小鼠模型, 允许解剖的 EV 介导的相互作用的肿瘤细胞和间充质干细胞 (MSCs)在体内。我们表明, 系统注射的人肿瘤 EV 培养的小鼠骨肉瘤移植通过激活 IL-6/STAT3 信号通路7强促进肿瘤的生长和转移形成。
最近的研究表明, 癌症电?...

肿瘤微环境积极参与了肿瘤发生和肿瘤进展的大部分 (如果不是全部) 方面, 包括转移形成和对治疗的抵抗力的发展1。这强调需要对前体肿瘤小鼠模型, 允许解剖复杂的肿瘤基质相互作用发生在肿瘤的利基。
在肿瘤微环境的许多细胞成分中, 间充质干细胞 (MSCs) 在多种癌症类型 (如乳腺癌、前列腺癌、脑肿瘤、多发性骨髓瘤和骨肉瘤) 中有强烈的促进作用2 ,3,4,5,6,7。MSCs 是驻留在各种成人和胎儿组织中的多能干细胞, 包括骨髓、脂肪组织、胎盘、脐血和其他8,9。为应对癌症产生的炎症信号, MSCs 向肿瘤部位迁移, 纳入肿瘤微环境, 最终分化为肿瘤支持细胞10。这些与癌症相关的 MSCs 提供了重要因素 (例如,生长因子、趋化因子、细胞因子和免疫抑制剂), 用于肿瘤细胞和周围基质的作用2,3,11,12,13. 虽然在众多的癌症模型中研究了癌症相关的 mscs 的促肿瘤作用, 但是肿瘤细胞重新编程 mscs 以形成促进癌症的利基的机制却不甚了解。在这里, 我们描述了一个同种异体原位移植模型的生成, 它特别允许通过细胞外囊泡 (EVs) 研究骨癌细胞与骨髓间充质干细胞之间的亲癌变相互作用。
EVs 是肿瘤与基质细胞间通讯的关键介质14。EVs 携带原细胞的功能生物分子, 包括蛋白质、血脂和调控 rna。一旦在细胞外空间释放, 这些囊泡可以被周围的细胞占用, 或者通过血液或淋巴循环携带到远处的部位, 并能深刻地影响靶细胞的行为。15,16, 17例如, 基质成纤维细胞对癌电动车的吸收可能导致上皮细胞分化支持血管生成和加速肿瘤生长体内 18 19, 内皮内部化细胞可以刺激肿瘤血管生成, 增加血管通透性16,20, 与免疫细胞的相互作用可能导致抑制抗肿瘤免疫应答21。
我们最近用一种生物发光的同种异体骨肉瘤模型证明, 肿瘤细胞释放出大量的电动车, 促使 MSCs 获得亲癌变和支持转移的表型。这种影响是由于 msc 细胞因子表达谱 (称为 "理学硕士教育") 的戏剧性变化, 并可通过管理治疗 interleukin-6 受体 (IL-6R) 抗体7来预防。我们的研究表明, 癌症电动车是 MSC 行为的关键调节剂, 从而为以微环境为目标的方法阻止骨肉瘤进展提供了理论依据。在此, 我们描述了一个逐步的协议, 以调查 EV 介导的肿瘤理学硕士互动在体内。该模型的目的是: 1) 明确定义的癌症 EV 诱导改变的肿瘤微环境, 2) 评估这种相互作用是如何促进骨肿瘤的生长和转移形成, 3) 研究是否干预EV 介导的串扰在体内防止癌症进展。

a preclinical mouse model of osteosarcoma to define the extracellular vesicle-mediated communication between tumor and mesenchymal stem cells

在肿瘤微环境中, 居民或被征募的间充质干细胞 (MSCs) 有助于多种癌症类型的恶性进展。在特定环境信号的影响下, 这些成体干细胞可以释放分泌介质, 从而加速肿瘤的生长和转移。定义肿瘤和骨髓间充质之间的串扰, 对于了解癌症进展的机制和确定治疗干预的新靶点至关重要。
癌细胞产生大量的胞外囊泡 (EVs), 这会深刻地影响肿瘤微环境或远处的靶细胞的行为。肿瘤电动车包围功能生物分子, 包括炎症 rna 和 (onco) 蛋白, 可以教育基质细胞, 以增强癌细胞的转移行为或参与转移前的利基形成。在这篇文章中, 我们描述了一个前肿瘤小鼠模型的发展, 它可以对 EV 介导的肿瘤和间充质干细胞之间的串扰进行具体评估。首先, 我们描述了肿瘤分泌的电动车的纯化和表征, 以及 MSCs 对电动汽车内化的评价。然后利用复用珠基免疫分析法, 对癌症电动车诱导的细胞因子表达谱的改变进行评价。最后, 我们说明了概括骨肉瘤的生物荧光原位异种移植小鼠模型的生成, 并显示了 EV 培养的骨髓间充质干细胞对肿瘤生长和转移形成的贡献。
我们的模型提供了一个机会来定义癌症电动车如何形成肿瘤支持的环境, 并评估是否封锁的 EV 介导的肿瘤和 MSCs 之间的沟通, 以防止癌症进展。

在这项研究中, 我们探讨了骨肉瘤分泌的电动车的能力, 以培养骨髓间充质干细胞向癌变和支持转移表型。我们表明, 骨肉瘤细胞释放外切样的电动车, 由 MSCs 内化。我们测量了癌症电动车诱导的细胞因子表达谱的变化, 并评价了 EV 培养的骨髓间充质干细胞对肿瘤生长和转移形成的影响。研究设计的一般表示形式在图 1中进行了说明。
