SOTMGF, a novel framework, enhances spatial multi-omics analysis by fusing diverse data types. It improves spatial domain identification and reveals molecular insights for biomarker discovery.

Area of Science:

  • Spatial biology
  • Multi-omics data integration
  • Computational biology

Background:

  • Spatial multi-omics technologies offer in situ molecular profiling.
  • Integrating multi-modal data for spatial domain identification and cell heterogeneity analysis remains challenging.

Purpose of the Study:

  • To develop SOTMGF, a self-supervised, goal-directed multi-view graph fusion framework for spatial multi-omics data.
  • To enhance spatial domain identification, data denoising, and detection of spatially variable molecular features.

Main Methods:

  • SOTMGF framework with five modules: pre-clustering, sparse feature processing, multi-view feature extraction and fusion, and multi-modality integration.
  • Iterative optimization of self-training and graph embedding within a unified framework.
