Primary Outcome Measures:
  • Safety assessment through clinical neurological and MRI evaluation. [ Time Frame: one year post transplant ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • MRI examination for post-transplant myelination [ Time Frame: one year post transplant ] [ Designated as safety issue: No ]

Enrollment: 4
Study Start Date: November 2009
Study Completion Date: December 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HuCNS-SC cells
Intracerebral implantation of HuCNS-SC via direct injection during surgery
 Biological: HuCNS-SC cells
intracerebral transplantation
Other Name: Human central nervous system stem cells

Detailed Description:

Enrolled subjects will be transplanted with HuCNS-SC cells into the brain and will receive immunosuppression for nine months. The study observation period is for one year after transplant surgery. Thereafter, subjects will be enrolled in a long-term observational follow-up study for four years.
