CD24 and breast cancer: Based on the expression of specific markers for the main cellular subpopulations in breast cancer samples (Figure 5D), we identified the aggregation of various cell populations (Figure 5C), including epithelial cells (EPCAM, KRT19, CD24), basal cells (TP63, KRT5, KRT14), endothelial cells (PECAM1, VWF), fibroblasts (COL1A1, COL1A2, and DCN), myeloid cells (CD68, CD163, and CSF1R), T cells (CD3D and CD3E) and B cells (CD19, CD79A, and MS4A1).
