Overview of graft-derived TH-positive innervation. (A) A 3D reconstruction showing the location and size of three graft deposits in the caudal, middle, and rostral putamen. (C–K) Extent of the graft-derived TH-positive innervation throughout the postcommissural putamen (positions of the sections indicated in A, arranged in a caudal-to-rostral order). (B) In contrast, the nongrafted putamen was completely devoid of TH-positive fibers. (Scale bars: 1 mm in B, 0.5 mm in D, 20 µm in E–G, 5 mm in H–K.)
