摘要:

多重成像(MI)能够在亚细胞分辨率下于独立成像通道中同时可视化多种生物标志物,为细胞类型异质性和空间组织提供有价值的见解。然而,当前的计算流程依赖于细胞分割算法,这些算法需要费力的微调,并可能因不准确的单细胞表征而引入下游错误。我们提出了一种无分割的深度学习方法,利用分组卷积从每个成像通道中学习可解释的嵌入特征,从而实现无需手动特征选择的稳健细胞类型识别。在来自神经母细胞瘤患者的180万个细胞的成像质谱流式细胞术数据集上验证,我们的方法能够准确识别已知细胞类型,展示了其可扩展性及对高维MI数据的适用性。

英文摘要:

Multiplex Imaging (MI) enables the simultaneous visualization of multiple biological markers in separate imaging channels at subcellular resolution, providing valuable insights into cell-type heterogeneity and spatial organization. However, current computational pipelines rely on cell segmentation algorithms, which require laborious fine-tuning and can introduce downstream errors due to inaccurate single-cell representations. We propose a segmentation-free deep learning approach that leverages grouped convolutions to learn interpretable embedded features from each imaging channel, enabling robust cell-type identification without manual feature selection. Validated on an Imaging Mass Cytometry dataset of 1.8 million cells from neuroblastoma patients, our method enables the accurate identification of known cell types, showcasing its scalability and suitability for high-dimensional MI data.
