Groups/Cohorts	Assigned Interventions
HuCNS-SC transplanted subjects in the lead-in phase Subjects who had HuCNS-SC transplant in the lead-in phase study CL-N01-PMD	Biological: HuCNS-SC transplant in the lead-in phase Long-term safety follow-up study

Detailed Description:

Only subjects who underwent HuCNS-SC transplantation under Protocol CL-N01-PMD will be enrolled in this long term follow-up study.

Subjects will return to the site six months and one year after completion of the Phase I study and then annually for a total study duration of four years. Phone calls will also be made by the Investigator to the subject's parent/legal guardian bi-annually to conduct a phone visit through the four-year duration of the study.
