Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • Imaging-based spatially resolved transcriptomics (imSRT) offers high-throughput, molecular-resolution spatial gene characterization within cells.
  • Conventional imSRT analysis uses gene count matrices, overlooking subcellular transcript heterogeneity crucial for defining cell states.

Purpose of the Study:

  • To develop a novel method, STARIT (Spatial Transcriptomics As Rasterized Image Tensors), for analyzing imSRT data.
  • To leverage subcellular transcript localization for enhanced cell-type and cell-state identification.

Main Methods:

  • STARIT converts imSRT data into image-based tensor representations.
  • Integrates these tensors with deep learning computer vision models for downstream analysis.
  • Validates performance using simulated and real imSRT datasets.

Main Results:

  • STARIT successfully distinguishes transcriptionally distinct cell types and separates cell states based on subcellular transcript localization in simulated data.
  • On real imSRT data, STARIT identified comparable cell types to conventional methods and revealed rotational variations.
  • The method captures biological insights missed by traditional gene count matrices.

Conclusions:

  • STARIT provides a standardized framework to encode subcellular molecular information from imSRT data.
  • Enables deeper insights into cellular heterogeneity and improves identification of cell types and states.
  • Facilitates advanced analysis of imSRT data by integrating spatial transcriptomics with deep learning.
