A Human angiogenesis array kit results showed five differentiated angiogenesis-related factors in the HeLa-sh-Ctrl and HeLa-sh-FASN groups. Each group contained three replicates of the culture supernatant mixture. B Heatmap of these five factors in A based on pixel analysis. C, D ELISA validation of MMP-9, Angiogenin, VEGF, PDGF-AA, and IGFBP-3 in the culture supernatant of the FASN-shRNA-treated HeLa and CaSki cells. E ELISA validation of MMP-9, Angiogenin, VEGF, PDGF-AA, and IGFBP-3 in the culture supernatant of the C33A-FASN-OE and C33A-vector groups. F, G Rescue experiments showed that the addition of PDGF-AA and IGFBP-3 could rescue the impaired effect of FASN knockdown on lymphangiogenesis. Tube length in tube formation assays was quantified. *P < 0.05; **P < 0.01; ***P < 0.001; #P < 0.05; ##P < 0.01; ###P < 0.001, CM-si-FASN-PDGF-AA/IGFBP-3 vs. CM-si-FASN-vehicle.
