In addition, we observed rare CAFs in the niche (Figure 1a), which can promote cancer formation and chemo‐resistance by sustaining cancer stemness.[23] Furthermore, previously identified CAF markers, CXCL14,[24]CALD1,[25] and IGFBP7,[25] were highly expressed in CAFs also based on our RNA‐seq data (Figure 1b). The gene discussed is CXCL14; the disease is cancer.
