Cell clustering and annotation of the TNBC scRNA-seq data. A The position of the p-value of PC_1 and PC_20 in the PCA relative to the uniform distribution (dashed line). Significant Pcs are located above the dashed line, with a smaller p-value. B distribution of the standard deviation of the P.C.s. Significant P.C.s have a larger standard deviation. C Visualization of the tSNE clustering results, with a two-dimensional display of aggregation and distribution of the cells, in which each color represents a cluster. D Visualization of the cell annotation results, in which each color represents a cell subset
