For xCell method, the infiltration scores of common lymphoid progenitor (P < 0.001), endothelial cell (P < 0.001), cancer associated fibroblast (P < 0.05), Hematopoietic stem cell (P < 0.01), mast cell (P < 0.01), T cell NK (P < 0.001), T cell CD4 + Th1 (P < 0.001), and stroma (P < 0.01) were different among three molecular subtypes (Figure 5C). Here, CD4 is linked to cancer.
