in this study , fetal day 17-18 striatal grafts were examined at 2 , 5-6 , 12 , and 44-48 weeks following their implantation into saline- or kainic acid-treated host caudate nucleus in order to compare the neuronal organization of the grafts and the host caudate nucleus and to determine whether the differentiation of graft tissue was influenced by the period of implantation or prior lesion of the host caudate nucleus with kainic acid .
