Tumor tissues contain both tumor and non-tumor cells, which include infiltrated immune cells and stromal cells, collectively called the tumor microenvironment (TME).Single-cell RNA sequencing (scRNAseq) enables the examination of taylor swift baby guitar heterogeneity of tumor cells and TME.In this review, we examined scRNAseq datasets for multiple cancer types and evaluated the heterogeneity of major cell type composition in different cancer types.We further showed that endothelial cells and fibroblasts/myofibroblasts in different cancer types can be classified into 28x48 mirror common subtypes, and the subtype composition is clearly associated with cancer characteristic and therapy response.
