Background: Neural stem cells (NSCs) since being a multi-potent neural crest originated cells, are able for self-replication, and differentiation to astrocytes, oligodendrocytes, or neurons. Therefore, it is expected that autologous transplantation of hNSCs to CNS, can be considered as a therapeutic approach for Parkinson's disease (PD). However, growth of human neural stem cells (hNSCs) is very slow, and they senesce after few passages, therefore enough amount of neural cells is very difficult to obtain to treat a number of patients.

Aim: The growth potential and survival length of the neural stem cells have to improved to make it practically feasible to use as a cell therapeutic regiment for PD. At the present time, cell co-cultures have been extensively used in cell functional research. We will study here whether co-culturing NSCs with another neural crest originated cells, Melanocytes (MCs), can increase the proliferation rate and Dopamine synthesis capacity of NSCs.

Methods: We compared the growth potential, synthesis of DOPAmine (DA), Brain-Derived Neurotropic Factor (BDNF) and Glial cell-Derived Neurotropic Factors (GDNF) by NSCs cultured alone and in co-culture system with MCs.

Results: hNSC’s doubling time increases by 2-3 times in co-culture condition. Survival length of hNSCs in co-culture system is beyond 25 passages, whereas senescence occurred after only 5-6 passages when cultured alone. DA production as well as BDNF and GDNF production by hNSCs is much more in co-culture system compared to hNSCs by itself, only.

Conclusion: A possible modification of hNSCs is possible by close association with melanocytes. A further study is required how these changes can be made beyond transient and subtle type.
