Objective To construct the recombinant adeno-associated virus vector with human bone morphogenetic protein 4 gene（AAV-hBMP4）. Methods The hBMP-4 gene primer was designed basing on the corresponding gene sequence in GenBank. EcoR I site was introduced into the upstream of the primer and Sal Ⅰ site into downstream. The hBMP-4 gene was amplifiedwith the template of EX-A0242-M01-hBMP-4, then was cloned into pUC18 vectorto construct recombinant plasmid pUC18-hBMP-4. The plasmids pUC18-hBMP-4 and plasmid pSNAV cut by EcoR Ⅰ and Sal Ⅰenzyme, the fragments were collected and linked with T4 DNA ligase at 16℃ over night, recombinant plasmid pSNAVhBMP-4 was obtained. The recombinant plasmid was then transfected into BHK21 cells using Lipofectamine TM2000. The G418 resistant cells were obtained consequently. Thesecells were infected with HSV1-rc/△UL2 which has the function of packaging andcopying the recombinant AAV. After purification, the construction of recombinant AAV-hBMP-4 was completed. Results The construction of the recombinant pSNAV-hBMP-4 was confirmed by PCR electrophoresis and digestion with restriction enzyme. The gene sequence in the recombinant pSNAV-hBMP-4 wascorrect. The virus titer was about 1.5×1012 μg/ml.The purity of the virus was more than 95% using the SDSPAGE method. Conclusion With this method, high virus titers and purity of AAV-hBMP-4 can be acquired successfully and it is useful to bone tissue engineering.
