2. 肿瘤微环境多组学整合分析新范式
全光谱技术可同时检测肿瘤细胞、免疫细胞及基质细胞的数十种标志物,为肿瘤异质性研究提供多维视角。例如,荷兰莱顿大学医学中心(Leiden University Medical Center)的研究团队在2023年发表于《Nature Communications》的研究中,利用全光谱流式细胞术,首次绘制了妊娠中期人类胎儿肠道免疫系统的发育图谱。该研究结合全光谱流式、成像质谱流式和单细胞测序技术,揭示了胎儿肠道免疫细胞的时空分布与功能特征。
该研究充分展现了全光谱流式在多色实验设计中的灵活性——在16色增殖方案基础上,仅需增加9种标志物即可扩展至25色功能分析方案,无需重新优化染料组合或调整激光配置。此外,光谱解析算法有效区分了自发荧光与目标信号,提升了稀有细胞群(如CD8αα+上皮内T细胞)的检测灵敏度。 参考文献—— Guo, N., Li, N., Jia, L. et al.
