Abstract:Aim To investigate the effect of β-nerve growth factor (β-NGF) gene transfected human umbilical vein endothelial cells (HUVEC) on cell function related to proliferation,monoclonal formation,cell cycle,apoptosis,migration. Methods The recombination human β-NGF gene expression eukaryotic plasmid with EGFP (pEGFP-N1) was transfected into HUVEC,HUVEC without transfected plasmid as the normal control group,HUVEC with empty vector (pEGFP-N1) as the negative control group,and-NGF gene transfection with the 1∶1000 K252a as the tyrosine receptor kinase A (TrkA) inhibition group.
