Abstract

OBJECTIVE: To construct recombinant adeno-associated virus (rAAV) vector containing angiopoietin-1 (ANG-1) gene and to express the ANG-1 in targeting cells. METHODS: ANG-1 cDNA was obtained from human spleen by RT-PCR and was inserted into AAV vectors to form rAAV ANG-1, the virus stocks in high titer were harvested. The rAAVANG-1 and rAAV GFP were transferred into pig mesenchymal stem cells and the expression of ANG-1 was detected by Western blot. RESULTS: The cloned ANG-1 cDNA was 1515bp in length which was in accordance with that reported previously. Titration of rAAVANG-1 stock was 9 X 10(11)v.g/ml. The expression of ANG-1 gene was detected in transfected cells. Forty-eight hours after rAAV GFP was transfected into mesenchymal stem cells, 55% cells expressed GFP. CONCLUSION: The constructed rAAV ANG-1 vector has successfully transfered and expressed in pig mesenchymal stem cells.
