Area of Science:

  • Oncology
  • Genomics
  • Bioinformatics

Background:

  • Cancer's molecular heterogeneity drives drug resistance and treatment failure.
  • Single-cell sequencing offers insights but lacks spatial context.
  • Understanding tumor heterogeneity is crucial for precise diagnosis and improved outcomes.

Purpose of the Study:

  • To review the applications of spatial transcriptomics in cancer research.
  • To highlight its role in understanding tumor heterogeneity and microenvironments.
  • To discuss future prospects and challenges of this technology in oncology.

Main Methods:

  • Review of existing literature on spatial transcriptomics in cancer.
  • Analysis of studies focusing on tumor heterogeneity, immune microenvironment, and matrix microenvironment.
  • Exploration of applications in pathological classification and prognosis.

Main Results:

  • Spatial transcriptomics provides crucial localization-indexed gene expression data.
  • It aids in discovering novel spatial-dependent mechanisms in cancer.
  • Applications span tumor heterogeneity, immune and matrix microenvironments, and cancer prognosis.

Conclusions:

  • Spatial transcriptomics is a powerful tool for deciphering cancer's complex heterogeneity.
  • It offers a spatial dimension lacking in other single-cell technologies.
  • Further development will enhance its impact on cancer diagnosis, treatment, and prognosis.
