We detected the FN1 expression in cervical cancer cells and cells cultured with FN1 substrate by immunofluorescence staining and qRT‐PCR, which showed that cervical cancer cells can secrete FN1 by themselves and a significant upregulation of FN1 expression in FN1 coated cells (Figure 6B,C; Figure S7A,B). The gene discussed is FN1; the disease is cervical carcinoma.
