In a recent report, TGF‐β was shown to induce peritumoral fibronectin deposition and tumor infiltration in basal cell carcinoma (Kuonen et al., 2018), which suggested that α5 might affect the expression and assembly of fibronectin through some TGF‐β responsive pathways, rather than a general effect on the activation state of fibroblasts. This evidence concerns the gene TGFB1 and basal cell carcinoma.
