Abstract:

BACKGROUND: Bone morphogenetic protein-7 can promote proliferation of bone marrow mesenchymal stem cells and has important significance in terms of inducing new bone formation.
OBJECTIVE: To observe the protein and mRNA expression of bone morphogenetic protein-7 in bone marrow mesenchymal stem cells transfected with bone morphogenetic protein-7.
METHODS: Rat bone marrow mesenchymal stem cells were isolated and cultured, and then identified by the morphology and cell surface markers. Lentiviral vectors carrying bone morphogenetic protein-7 were constructed to transfect bone marrow mesenchymal stem cells. After total RNA extraction, the protein and mRNA expression of bone morphogenetic protein-7 was detected by RT-PCR and western blot methods.
RESULTS AND CONCLUSION: PLV-sfGFP(2A)-BMP7 recombinant plasmids were successfully constructed and transferred into rat bone marrow mesenchymal stem cells. The mRNA and protein expression of bone morphogenetic protein-7 in the transfection group was significantly higher than that in the blank vector and blank groups (P < 0.05), indicating exogenous bone morphogenetic protein-7 gene is effectively integrated into the bone marrow mesenchymal stem cells.
