Abstract:
BACKGROUND: PEX gene can interfere with the invasion acts of malignant glioma. Bone marrow mesenchymal stem cells (MSCs) are a new type of targeted cell vector on cancer therapy. OBJECTIVE: To construct MSCs stably expressing PEX gene.METHODS: PEX eukaryotic expression vector was constructed by molecular cloning, and identified the recombinant plasmid pcDNA3.1(+)-PEX by restriction endonuclease digestion and sequencing. After transfected with MSCs, the eukaryotic expression vector expression in MSCs was verified by immunocytochemical method. The MSCs stably expressing PEX was established by G418 selection, and then was detected by using reverse transcriptase-polymerase chain reaction.RESULTS AND CONCLUSION: The MSCs stably expressing PEX gene is successfully established, in which PEX gene is highly expressed at both gene level and protein level.
