Corroboration of the progenitor identity by nestin immunohistology. a The diagram of the infusion tube, migratory path, and graft. The areas nearby the graft and the migratory path marked by squares were photomicrographed. b A closer view of the migrating NPCs taken from the CXCL12-treated group. The NPCs were observed with both PB and nestin immunoreactivity. c The NPCs of the graft treated with CXCL12 infusion were positive for both nestin and PB. d Little migration occurred in the vehicle-treated group. e The graft view from the vehicle-treated group. Neither PB staining nor nestin immunoreactivity was observed beyond the graft site
