ICAM-1 was broadly expressed, including on non-proliferating tumor cells in the proximal region (Figure 5a,f) and CSCs in the border region (Figure 5b,f), which increased the repertoire of cells typically expressing this marker, such as endothelial cells [38,51], N1 neutrophils (Figure 5a,b,e) [43,44], and licensed DCs (Figure 5b,e) [41,42]. Here, ICAM1 is linked to neoplasm.
