Spatial omics technologies for understanding molecular status associated with cancer progression

Area of Science:

• Cancer genomics and molecular pathology.
• Development and application of spatial omics technologies.

Background:

• Cancer cells adapt to the tumor microenvironment by altering gene expression.
• Tumor microenvironment poses challenges to cancer cell progression and survival.

Purpose of the Study:

• To review recent advancements in spatial omics, particularly spatial transcriptomics.
• To highlight how these technologies retain spatial and histopathological information in cancer tissues.
• To discuss the utility of spatial analysis in understanding cancer biology and heterogeneity.

Main Methods:

• Review of latest spatial analytical technologies and platforms.
• Discussion of key research papers utilizing spatial omics.
• Introduction of specific spatial omics platforms and their capabilities (e.g., single-cell resolution).

Main Results:

• Spatial transcriptome analysis provides comprehensive omics data for cancer cells and surrounding cells (immune cells, fibroblasts).
• Emerging platforms offer single-cell or subcellular resolution for detailed spatial profiling.
• These technologies enable investigation of molecular events linked to cancer progression.

Conclusions:

• Novel spatial omics technologies, combined with histopathology, are crucial for understanding intratumor heterogeneity.
• Enhanced knowledge of tumor biology can lead to overcoming therapeutic resistance.
• This approach promises improved patient stratification and personalized cancer treatment strategies.
