Liquid biopsy has remarkably facilitated clinical diagnosis and surveillance of cancer via employing a non-invasive way to detect cancer-derived components, such as circulating tumor DNA and circulating tumor cells from biological fluid samples. The cancer-derived exosomes, which are nano-sized vesicles secreted by cancer cells have been investigated in liquid biopsy as their important roles in intracellular communication and disease development have been revealed. Given the challenges posed by the complicated humoral microenvironment, which contains a variety of different cells and macromolecular substances in addition to the exosomes, it has attracted a large amount of attention to effectively isolate exosomes from collected samples. In this review, the authors aim to analyze classic strategies for separation of cancer-derived exosomes, giving an extensive discussion of advantages and limitations of these methods. Furthermore, the innovative multi-strategy methods to realize efficient isolation of cancer-derived exosomes in practical applications are also presented. Additionally, the possible development trends of exosome separation in to the future is discussed in this review.
液体活检通过采用非侵入性方法来检测源自癌症的成分,如生物流体样本中的循环肿瘤DNA和循环肿瘤细胞,极大地促进了癌症的临床诊断和监测。癌症来源的外泌体是癌细胞分泌的纳米级囊泡,由于其在细胞内通讯和疾病发展中的重要作用已被揭示,因此在液体活检中受到了研究。鉴于复杂的体液微环境带来的挑战,除了外泌体之外,该微环境还包含各种不同的细胞和大分子物质,因此如何从收集的样本中有效分离外泌体引起了广泛关注。在这篇综述中,作者旨在分析分离癌症来源外泌体的经典策略,对这些方法的优缺点进行广泛讨论。此外,还介绍了在实际应用中实现高效分离癌症来源外泌体的创新多策略方法。此外,本综述还讨论了外泌体分离未来可能的发展趋势。
