  • To integrate cell boundary information with spatial gene expression data for higher accuracy.
  • To improve the understanding of single-cell contributions to tissue biology.

Main Methods:

  • STCellbin aligns cell membrane/wall staining images with spatial gene expression maps using nuclei staining images.
  • Advanced cell segmentation algorithms are employed to accurately delineate cell boundaries.
  • The software was validated on mouse liver and Arabidopsis seed datasets.

Main Results:

  • STCellbin accurately identifies cell boundaries and generates reliable single-cell spatial gene expression profiles.
  • The software demonstrated superior performance compared to existing methods on tested datasets.
  • Accurate cell boundary detection significantly improves the quality of spatial gene expression data.

Conclusions:

  • STCellbin provides a robust solution for high-confidence single-cell spatial gene expression profiling.
