    Abstract:
    This study was purposed to construct the recombinant retroviral vector containing human homeobox gene hoxA10 and to establish the packaging cell lines which stably produce viruses. The whole coding region of hoxA10 gene was amplified by PCR and inserted into the retroviral vector MSCVneo. The recombinant vector was identified by DNA sequencing. The recombinant and control retroviral vectors were transfected into the packaging cell line PT67 by liposome Lipofectamine(TM) 2000. These cell lines stably producing retrovirus were isolated following G418 selection. The viral suspension was harvested and the viral titer was determined by NIH3T3 cells. The results showed that the recombinant retroviral vector was proved to encode hoxA10 genes by sequencing. The cell lines efficiently producing virus were screened by G418 and designated as PT67/MSCVneo and PT67/MSCVneo-hoxA10. The titers of them were 5 x 10(5) CFU/ml and 4 x 10(4) CFU/ml respectively. It is concluded that the recombinant retroviral vector containing homeobox gene hoxA10 and the stably packaging cell lines which efficiently and correctly produce viruses are successfully constructed, which provides a basis for further exploration of the hoxA10 gene function in the regulation of hematopoiesis.
