Construction of Recombinant Lentivirus Containing Human HoxA4 Gene and Their Transfection Efficiency in Human Umbilicalcord Mesenchymal Stem Cells
摘要
Abstract
Objective To construct recombinant lentivirus vector containing human H0XA4 gene and test its transfection in human umbilicalcord mesenchymal stem cells ( hUCMSCs ) . Methods H0XA4 gene was amplified from plasmid H0XA4 - MSCV by PCR technique and sub-cloned into the expression plasmid of lentiviral-GFP-CTB vector. The lentiviral-GFP-H0XA4 expression vector was constructed and confirmed by endoenzyme digestion and sequencing. Recombinant Lentiviral-GFP-HOXA4 was produced by 293 T cells following the co-transfection of lentiviral-GFP-H0XA4 and packaging plasmids pRsv-REV pMDlg-pRRE and PMD2G. The recombinant lentiviral-GFP-H0XA4 was then used to infect hUCMSCs. Results The recombinant lentiviral-GFP-H0XA4 was produced successfully. High-purified virus supernatant was obtained, with virus titer of 2. 11 x 108 TU/ml and efficient infection in hUCMSCs expressing green fluorescence ( 95. 37% ) 60 h after transfection. Conclusion The lentiviruse vector with human H0XA4 cDNA was established successfully, with effective transfection in hUCMSCs.关键词
