Development of human striatal anlagen after transplantation in a patient with Huntington's disease

Replacement of damaged neuronal Population by fetal tissue transplantation represents a potential treatment for neurodegenerative diseases. Consistent Success has been achieved with fetal striatal transplantation in Huntington's disease animal models and patients. We report the neo-generation of metabolically active tissue with striatum-like imaging features after transplantation of striatal primordia in a patient with Huntington's disease. This Study represents the first in vivo demonstration that a human striatal anlagen, transplanted into the adult human brain, is able to progress in its development and to generate a new anatomical structure in the host, without evidence of neoplasia or teratoma.
