Abstract:
:Nerve growth factor (NGF) is required for the differentiation and maintenance of sympathetic and sensory neurons. In the present study, the recombinant expression of human nerve growth factor beta (hNGF-β) gene in rabbit bone marrow mesenchymal stem cells (rMSCs) was undertaken. Recombinant vector containing hNGF-β was constructed and transferred into rMSCs, the expressions of the exogenous in rMSCs were determined by reverse transcriptase PCR (RT-PCR), ELISA and Western blot, whereas the biological activity of recombinant hNGF-β was confirmed using PC12 cells and cultures of dorsal root ganglion neurons from chicken embryos. The results showed that the hNGF-β gene expressed successfully in the rMSCs, a polypeptide with a molecular weight of 13.2 kDa was detected. The maximal expression level of recombinant hNGF-β in rMSCs reached 126.8012 pg/10(6) cells, the mean concentration was 96.4473 pg/10(6) cells. The recombinant hNGF-β in the rMSCs showed full biological activity when compared to commercial recombinant hNGF-β.
