In light of significance of TGFβ1, SHH, EGFR, and LEF‐1 in the proliferation and migration of cancer cells,22, 42, 43, 44, 45 we examined the differential expression of those proteins in the cell lysis solution of NFs and CAFs and paid our attention to the different expression of SHH. The gene discussed is EGFR; the disease is cancer.
