ABSTRACT
Cell therapy have a great potential for the treatment of neurodegenerative disease, such as Parkinson's disease (PD). Human umbilical cord-derived mesenchymal stromal cells (hUC-MSCs) have been reported to have multipotent differentiation ability. However, the therapeutic impact and mechanisms of dopamine neuronal differentiation from hUC-MSCs in PD are not determined. Here we developed a new protocol to induce dopamine neuron conversion from hUC-MSCs by addition of the growth cocktail containing noggin, CHIR99021, SHH, FGF8, TGFβ, GDNF, and BDNF. Then we transplanted the hUC-MSCs and the growth factor cocktail into the lesion side of the midbrain of 6-OHDA lesioned rat model of PD. The effects of hUC-MSC transplantation on the dopaminergic neuronal differentiation and motor behaviors of the rats were investigated. We found that in the presence of these molecules, the cultured hUC-MSCs showed a high efficient DA neuronal conversion in vitro. In combination with the growth cocktail, grafted hUC-MSCs also showed a highly efficient DA neuronal conversion in the midbrain of 6-OHDA lesioned rats. Both the grafted hUC-MSCs and the differentiated TH-positive neurons survived in 6-OHDA lesioned rats during the post-grafting period of 16 weeks. The hUC-MSCs-derived TH-positive neurons displayed the same electrophysiological profile as DA neurons in vivo. More importantly, rats with transplanted hUC-MSCs showed progressive improvements in motor behaviors compared to controls from weeks 4 to 16 post-grafting. These results demonstrated the efficacy and usefulness of the growth cocktail in combination with hUC-MSC transplantation in 6-OHDA lesioned rats and provided a promising cell-based treatment strategy for the PD patients.
