Trends Biotechnol:新型肿瘤细胞富集系统,让循环肿瘤细胞无处可逃!

2018-05-10 Michael,Zoe 转化医学网

在血流中对循环肿瘤细胞(CTC)进行计数可以预测癌症患者的预后和存活率。 然而,CTC的稀有性和异质性使它们在作为生物标志物使用时产生巨大的困难。 最近的研究报道了癌症患者中存在的新型循环非癌性肿瘤衍生细胞, 包括癌症相关巨噬细胞,肿瘤 - 内皮簇(TEC)和癌相关成纤维细胞(CAF)。目前的标记依赖性CTC富集系统对这组循环细胞并无特异性。 为了最大限度地发现癌症患者中有用的循环生物标志物,研究

在血流中对循环肿瘤细胞(CTC)进行计数可以预测癌症患者的预后和存活率。 然而,CTC的稀有性和异质性使它们在作为生物标志物使用时产生巨大的困难。 最近的研究报道了癌症患者中存在的新型循环非癌性肿瘤衍生细胞, 包括癌症相关巨噬细胞,肿瘤 - 内皮簇(TEC)和癌相关成纤维细胞(CAF)。目前的标记依赖性CTC富集系统对这组循环细胞并无特异性。 为了最大限度地发现癌症患者中有用的循环生物标志物,研究人员使用基于尺寸适应型富集技术来分离循环中的癌性和非癌性细胞。

在循环中新的肿瘤衍生细胞类或可改善癌症诊断

在寻找血液中特定的癌症生物标志物时,循环肿瘤细胞(CTCs)和循环非细胞DNA(cfDNA)领域已成为个体化药物和液体活检的潜力先驱。 在一些癌症(如非小细胞肺癌NSCLC)中的EGFR突变)中突变cfDNA的检测已经非常成功,但是将单个细胞单元(而不是DNA的片段)可以在研究癌症转移和治疗反应中起到巨大作用。

不同类型的循环细胞在癌症诊治过程中具有很大临床意义

CTC研究中的重要观察对象包括循环中非典型的细胞群。循环肿瘤微栓子(CTM)是三个或更多细胞彼此粘附的细胞群并且呈现细胞角蛋白阳性和CD45阴性。 很难想象,这样大的团簇在物理上可能在循环中移动而不会造成阻塞。直到研究人员证明,从癌症患者身上分离出来的大细胞团可以灵活地重组形成单个细胞用以通过狭窄的毛细血管。由于它们与肿瘤上皮细胞的相似性,CTM被认为是恶性细胞的一类。 现在有证据表明CTM具备异质性:其中一些是非恶性肿瘤来源的内皮细胞或巨噬细胞样细胞。

选择性捕获CTC和CTDC装置应考虑的关键因素

循环肿瘤源细胞(CTDC)与CTC共同被CTC富集装置所分离。 CTC富集装置通常依赖肿瘤细胞和血细胞的两个关键差异性质:肿瘤细胞大小和标记物如EpCAM的蛋白质表达。 这些是与CTDCs与白血细胞不同的特性。 因此,无标志型尺寸技术最适合于CTC和CTDC的分离。

促后富集稀少细胞分析系统的最新技术

① 细胞团簇的微流控液滴分选系统

② 高通量细胞表型分析

③ 单细胞分辨率Western印迹技术



尽管循环肿瘤细胞领域的设备能够显着富集目标细胞,但仍然需要高通量的方法来鉴定感兴趣的细胞,然后还要再进行繁琐而昂贵的操作。 研究人员预计下一步将CTC富集设备与高通量细胞分析技术相结合。
