Axon outgrowth from the grafts: A) Horizontal section immunostained for GFP to reveal GFP-labeled axons extending longitudinally to both the rostral and caudal ends of the 15 mm long block containing the injury site. This is from Rat #25, which had a category 2 morphology. Arrow indicates highly ramified cells 1–2 mm from the graft with the morphology of astrocytes. B) GFP-positive axons in the lateral column and gray matter about 500 µm caudal to the graft C) GFP-positive axons in the lateral column and gray matter at the caudal end of the block GM = gray matter. D) Halo of GFP-positive axons surrounding the central canal and nests of GFP-positive axons in the lateral column; “e” indicates the region illustrated at high magnification in panel E. F) Halo of GFP-positive axons surrounding the central canal. G) Region of the lateral column from a section near the one illustrated in E co-stained for GFP (green) and MAP2 (red). Note green GFP-positive varicosities investing the MAP2 positive dendrites that extend into the lateral column. GM = gray matter.
