PTX3 and fibrosarcoma: At variance, no significant differences were observed between mock- and PTX3-trasfected MC17-51 and HT-1080 cells for their capacity to repair a wounded cell monolayer (Supplementary Figure 4), thus indicating that PTX3 overexpression does not affect the motility of fibrosarcoma cells whose migratory capacity might be regulated by FGF/FGFR independent signaling pathways.
