TACC3 and squamous cell carcinoma: In line with this previous result, we detected FGFR3-TACC3 fusions only in uterine cervical squamous cell carcinoma but not adenocarcinoma (Fig. 1a and Supplementary Table 1) and demonstrated that transfection of FGFR3-TACC3 fusion transformed the cervical epithelial cell line established from the ectocervix (Ect1/E6E7) to squamous cell carcinoma.
