Figure 2. Single cell sequencing analysis. (A, B) Quality control of single cell sequencing data. (C) Cells were evenly distributed among the three samples, and no obvious batch effect was observed. (D) All cells are grouped into 26 clusters. (E, F) Cell annotation. All cells were annotated as basal epithelial cell, endothelial cell, luminal epithelial cells, macrophage, stromal cells and T cells. (G) According to the LLPS-related genes, the cells were divided into high-LLPS group and low-LLPS group, and the differentially expressed genes between the two groups were obtained.
