Primary Outcome Measures:
  • Neuronal differentiation into dopaminergic neurons [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Differentiation of at least 10% of dopaminergic neurons is targeted as the primary outcome measure


Biospecimen Retention:   Samples With DNA

Brain tissue obtained during neurosurgical procedures yields undifferentiated neural stem cells that are subsequently expanded.


Estimated Enrollment: 20
Study Start Date: June 2011
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Neural stem cells Procedure: Harvesting of neural stem cells
During neurosurgical procedures, tissue samples are obtained along trajectory of implanted electrodes or removal of stimulators previously implanted.

Detailed Description:

In this project the investigators propose to analyze tissue samples from different nervous system regions obtained during neurosurgical procedures in order investigate the presence of neural stem cells in different cerebral areas. The investigators will also evaluate techniques for neural stem cell cryopreservation, for possible future therapeutic uses. Patients with degenerative neurological disorders like Parkinson's disease undergoing neurosurgical procedures meeting our selection criteria will be candidate for this study.
