克服理解和治疗癌症的挑战需要可靠的患者衍生癌症模型(PDMCs)。几十年来,癌症研究和治疗发展主要依赖于癌细胞系,因为它们的普遍性、可重复性和易于维护。然而,在细胞系中进行的研究结果很少在体内重现,也很少直接转化为患者。肿瘤微环境(TME)、肿瘤-基质相互作用以及与宿主免疫细胞的关联会产生肿瘤表型和复杂性的深刻变化,这在传统的单层细胞培养中是无法捕捉到的。在本章中,我们介绍了各种癌症外植体模型,并根据具体的研究目的讨论了它们的适用性。我们将讨论这些模型在基础科学问题、药物筛选/开发以及个性化、精准医疗方面的适用性。我们还考虑后勤因素,如资源成本、技术难度和可及性。我们完成本章的实用指南,旨在帮助读者选择癌症外植体模型系统(s),最好地解决他们的研究目标。
Overcoming the challenges of understanding and treating cancer requires reliable patient-derived models of cancer (PDMCs). For decades, cancer research and therapeutic development relied primarily on cancer cell lines because of their prevalence, reproducibility, and simplicity to maintain. However, findings from research conducted in cell lines are rarely recapitulated in vivo and seldom directly translatable to patients. The tumor microenvironment (TME), tumor-stromal interactions, and associations with host immune cells produce profound changes in tumor phenotype and complexity not captured in traditional monolayer cell culture. In this chapter, we present various cancer explant models and discuss their applicability based on specific research aims. We discuss the appropriateness of these models for basic science questions, drug screening/development, and for personalized, precision medicine. We also consider logistical factors such as resource cost, technical difficulty, and accessibility. We finish this chapter with a practical guide intended to help the reader select the cancer explant model system(s) that best address their research aims.
