中文摘要
理解肿瘤微环境(TME)内肿瘤与宿主组织之间的相互作用,对于指导药物开发至关重要。TME的免疫肿瘤学特征可决定癌症是进展还是对免疫治疗产生应答。通过刻画免疫细胞和癌细胞的表型、功能状态和增殖状态来绘制TME图谱,可以推进药物发现。由于癌症样本中存在大量细胞类型和生物标志物,通常需要多重成像方法来捕捉这种复杂性,而AI引导的分析平台则可从这些数据丰富的实验中提取有意义的见解。由于肿瘤内异质性以及不同癌症类型间的表达差异,一种在多样组织切片中检查生物标志物panel的多肿瘤工作流程能够通过实现差异生物标志物分析、共表达分析和癌症特征发现,提供额外价值。为此,我们利用Cell DIVE多重成像平台,采用一种新型染料偶联策略以及经验证的抗体panel和专用染料,对多种癌症类型进行多重成像。随后使用Aivia分析了肿瘤样本间的生物标志物表达谱和表型分类。此外,有监督和无监督聚类分析均揭示了不同肿瘤类型间独特的癌症特征。通过将Cell DIVE平台的高通量能力与新开发的专用panel和染色试剂相结合,免疫肿瘤学研究人员可以全面理解癌症样本内发生的生物学过程,并识别关键分子靶点。这一整合工作流程为肿瘤-免疫动态提供了更深入的见解,衔接基础研究与临床应用,以加速可操作生物标志物和治疗靶点的发现。

Understanding the interplay between tumor and host tissues within the tumor microenvironment (TME) is critical for guiding drug development. Immuno-oncology features of the TME can determine whether cancers progress or respond to immunotherapies. Mapping the TME by characterizing the phenotype, functional state, and proliferative status of immune and cancer cells can advance drug discovery. Because of the considerable number of cell types and biomarkers present in cancer samples multiplexed imaging approaches are often required to capture this complexity, while AI-guided analysis platforms can extract meaningful insights from these data-rich experiments. Owing to intra-tumor heterogeneity and expression differences across cancer types, a multi-tumor workflow that examines biomarker panels in diverse tissue sections provides additional value, by enabling differential biomarker profiling, co-expression analysis, and cancer signature discovery. To this end, we utilized the Cell DIVE multiplexed imaging platform to perform multiplex imaging across several cancer types using a novel dye-conjugation strategy with validated antibody panels and specialized dyes. Biomarker expression profiles and phenotypic classifications across the tumor samples were subsequently analyzed using Aivia. In addition, both supervised and unsupervised clustering analysis revealed distinct cancer signatures across tumor types. By combining the high-throughput capabilities of the Cell DIVE platform with newly developed specialized panels and staining reagents, the immune-oncology researcher can gain a comprehensive understating of the biological processes occurring within cancer samples and identify key molecular targets. This integrated workflow provides deeper insight into tumor-immune dynamics, bridging basic research and clinical applications to accelerate the discovery of actionable biomarkers and therapeutic targets.
