ABSTRACT
In order to investigate the special role of HOXB4 in expansion and self renewal of hematopoietic stem cells, the cDNA of HOXB4 was extracted and cloned from umbilical cord blood mononuclear cells by using RT-PCR. Then the eukaryotic expression bicistronic plasmid vector pIRES2-EGFP/HOXB4 was designed and constructed after cutting HOXB4 and pIRES2-EGFP respectively by restriction enzyme EcoRI and BamHI. The recombinant plasmid was delivered into competent cells of Escherichia coli. The successful construction of plasmid was confirmed by the identification of endonuclease cutting and sequencing. The results showed that the HOXB4 cDNA was cloned successfully from umbilical cord blood mononuclear cells and the recombinant eukaryotic expression bicistronic plasmid vector was constructed, and then introduced it into 293T cells successfully. It is concluded that a pIRES2-EGFP/HoxB1 eukaryotic expression bicistronic plasmid vector has been constructed successfully, which results provide a useful material basis for exploration of HoxB4 function in the proliferation and differentiation of hematopoietic cells.
