On these bases, we moved to large‐scale MIF analyses and stained 326 samples from 292 patients for the expression of CD8 (tumour infiltrating T cells), CD68 (tumour infiltrating monocyte/macrophages), cytokeratins (tumour cells), and nuclei, along with CD274 (PD‐L1) (Figure 2A). Here, CD274 is linked to neoplasm.
