FGF2 and cervical cancer: Notably, FGF-2, PDGF receptor-α, and PDGF receptor-β were found to be expressed in the stroma of 9/11, 12/12, and 9/9 cervical cancers, respectively, whereas expression in the overt squamous cancer cells was not consistently detected, the exception being a single case that expressed PDGF receptor-β (Figure S7 and Table S2).
