Objective  To construct gene-modified hepatic stem cells (WB-F344 cells), which have rat IL-13 gene and can secrete the recombinant rat IL-13 cytokine in the cells.
Methods  Firstly, the rat IL-13 sequences were synthesized. Then the sequences were amplificated in bacterium coli after recombinated with pWPXL-MOD plasmid. After PCR and sequence identification, the positive clones were packaged into lentivirus. After detecting the virus titer, the WB-F344 cells with constructed lentivirus vector with rat IL-13 gene were cultured, then the valid targets (expression level of the IL-13) were detected by real time-PCR and Western blot in cultured WB-F344 cells on 5 days.
Results  The valid DNA of rat IL-13 was recombinated and packaged in lentivirus vector. The recombinant gene sequence was correct by checking with gene sequence test. Then the recombinant was introducted into the WB-F344 cells cultures. The best multiplicity of infection (MOI) value for effective transfection was 5. IL-13 had been detected on day 5 after transfection by checking with real-time PCR and Western blot.
Conclusion  The recombinant rat IL-13 gene with lentivirus vector is constructed and gene-modified WB-F344 cells are cultured successfully, which can be used in next animal experiment.
