PDCD1 and basal cell carcinoma: For the GES12814 dataset, advanced basal cell carcinoma (BCC) samples from eleven patients were subjected to scRNA‐seq before and after anti‐PD‐1 therapy.[28] We clustered the cells originally annotated as monocytes/macrophages into three types of TAMs: C1QC+ TAMs, FCN1+ monocytes/macrophages, and other monocytes/macrophages (Figure S14B, Supporting Information).
