A map of human breast cancer: new players in stromal-immune crosstalk.

Prominent accumulation of mesenchymal cells within tumors has long been appreciated, and recent studies suggest molecular and functional diversity of stromal components. In this issue, Wu et al (2020) employed single-cell RNA sequencing of primary human breast tumors and identified new subsets of stromal mesenchymal cells with distinct transcriptional profiles, tissue localization, and associative immune microenvironments.
