VEGFA and breast cancer: In previous studies, iCAFs were identified as the primary source of cytokines in BC.[20] To investigate the expression levels of various cytokines, we examined ICAM1+ iCAFs in recurrent tumors and found that CCL2, IL‐6, TGFβ, CTGF, FGF2, FGF7, and VEGFA were significantly enriched (Figure6A).
