TL;DR

This paper reviews how combining different techniques helps understand the tumor environment in endometrial cancer better.

Contribution

It is the first comprehensive review integrating scRNA-seq, ST, and IHC in endometrial cancer.

Findings

Combining scRNA-seq, ST, and IHC provides insights into tumor heterogeneity and cell interactions.

These methods help identify key biomarkers and therapeutic targets in endometrial cancer.

The integration of technologies enhances understanding of the tumor microenvironment dynamics.

Abstract

Endometrial cancer is regarded as one of the most prevalent malignancies in women globally. Despite the advancements brought by multiple therapeutic strategies, the efficacy and effectiveness of treatment still appear to be diminished. Therefore, this accentuates the importance of understanding the tumour microenvironment (TME). Conventional methods, including immunohistochemistry (IHC), along with recently emerged techniques like single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST), have rejuvenated the notion of deciphering TME. From deconstructing tumour heterogeneity, identifying cell populations that play significant roles in treatment response, to discovering key biomarkers and therapeutic targets, these technologies lay the base for innovations. Importantly, this is the first comprehensive review that brings together scRNA-seq, ST, and IHC in Endometrial cancer. Merging these methods is geared towards creating a better grasp of the dynamics and interactions between diverse cells and the TME.
