Construction and identification of rat GDNF gene recombinant retroviral vector and gene transfection to NSC / 生物医学工程学杂志

ABSTRACT

By genetic recombinant technique, the rat GDNF cDNA was recombinated to the retroviral vector pLXSN. The recombinant plasmid pLXSN-GDNF was verified by digestion with restriction endonucleases and PCR. Then neural stem cells (NSCs) were infected with pLXSN-GDNF. Immunocytochemistry, RT-PCR and western-blot were used to detect the transfection effect. Results showed that GDNF cDNA was cloned into retroviral vector pLXSN correctly, and the pLXSN-GDNF can infect NSCs efficiently. These results provide the possibility for transplantation and gene therapy with GDNF of nervous system diseases and injury.
