Differential effects of DCS on graft core volume and TH-ir cell count. A, Anodal stimulation resulted in an increased transplant survival reflected in a significantly larger graft core volume compared to sham, which was not significant with cathodal DCS. B, GFP graft cores are illustrated by representative micrographs from each DCS group. Scale bar: 250 µm. C, The number of TH-ir cells in the anodal group was higher compared to the sham DCS group; no increase was present with cathodal DCS. D, TH-ir cells as well as fiber outgrowth are illustrated by representative micrographs from each DCS group. TH-ir cells did not migrate out of the graft core. Scale bars: slice, both hemispheres 1 mm; high-magnification inset, 100 µm. Mean ± SEM; two-tailed Student’s t test each active stimulation versus sham; *p < 0.05.
