准确建模肿瘤生物学和测试患者来源细胞的新疗法对于开发针对患者特定疾病的个性化治疗方案至关重要。血管化微肿瘤(VMT),或“芯片上的肿瘤”,是一种生理临床前癌症模型,在透明的微流控平台内结合了天然人类肿瘤微环境的关键特征,允许体外快速药物筛选。在此,我们优化了使用新鲜结直肠癌(CRC)活检和手术切除来产生患者源性VMT (pVMT)的方法,以测试个体患者水平的药物敏感性。在对标准化疗和TGF-βR1抑制的反应中,我们观察到来自6例患者活检的pVMT之间的异质性反应,pVMT概括了实际结直肠癌肿瘤的肿瘤生长、组织学特征、代谢异质性和药物反应。我们的研究结果表明,提供pVMT中患者来源的肿瘤细胞快速信息的转化基础设施,如本研究所建立的,将支持改善患者预后的努力。
Accurately modeling tumor biology and testing novel therapies on patient-derived cells is critically important to developing therapeutic regimens personalized to a patient’s specific disease. The vascularized microtumor (VMT), or “tumor-on-a-chip,” is a physiologic preclinical cancer model that incorporates key features of the native human tumor microenvironment within a transparent microfluidic platform, allowing rapid drug screening in vitro. Herein we optimize methods for generating patient-derived VMT (pVMT) using fresh colorectal cancer (CRC) biopsies and surgical resections to test drug sensitivities at the individual patient level. In response to standard chemotherapy and TGF-βR1 inhibition, we observe heterogeneous responses between pVMT derived from 6 patient biopsies, with the pVMT recapitulating tumor growth, histological features, metabolic heterogeneity, and drug responses of actual CRC tumors. Our results suggest that a translational infrastructure providing rapid information from patient-derived tumor cells in the pVMT, as established in this study, will support efforts to improve patient outcomes.
