Objective To construct IL-18 gene in human umbilical cord mesenchymal stem cells for exploring a means of tumor targeted gene therapy. Methods hUMSCs were isolated and cultured in vitro.The immunophenotype of hUMSCs was detected by flow eytometry.The lentivirus vector containing human IL-18 gene was constructed and transfected into hUMSCs.The IL-18 mRNA and protein expression level was detected by semi-quantitative RT-PCR and Western blot. Results hUMSCs were isolated and cultured successfully.The FACS indi...
