Abstract
The neural stem cells (NSCs) have the ability to self-renew, and to migrate to pathologically altered regions of the central nervous system. Glial cell derived neurotrophic factor (GDNF) could protect dopamine neurons and rescue motor neurons in vivo, which has been proposed as a promising candidate for the treatments of degenerative neurological diseases. In order to combine the advantages of neurotrophic factors and stem cells in clinical therapy, we established the modified hNSCs that has site-specific integration of GDNF gene by using recombinant adeno-associated virus (rAAV) vectors. The hNSCs were co-infected by rAAV2-EGFP-GDNF and rAAV2-SVAV2 which provide integrase to specifically integrate GDNF gene into AAVS1 site. The GDNF-hNSCs maintained their original stem cell characteristics and the ability to differentiate into neurons in vitro. In the animal model, the GDNF-hNSCs were specifically transplanted into CA1 area of hippocampi and could migrate to the dentate gyrus region and differentiate into neuronal cells while maintaining GDNF expression. hNSCs with GDNF gene site-specific integration at AAVS1 by using AAV vectors retained their stemness and effectively expressed GDNF, which indicates the potential of employing transplanted hNPCs for treatment of brain injuries and degenerative neurological diseases.
