While both groups demonstrated a marked detection of VEGF levels relative to the other cytokines, HGF-preconditioned NPCs secreted less VEGF in comparison to untreated NPC controls (5,361.20 ± 836.88 vs. 7,773.04 ± 1,446.81 pg/ml; p < 0.0001). The gene discussed is HGF; the disease is nasopharyngeal carcinoma.
