Fig. 6. Homotopic transplants of PKH26-labeled LGE cells. (A) Coronal section of E17.5 embryonic brain four days after transplantation reveals accumulation of LGE cells in the striatum and absence of LGE cells in the neocortex. Some labeled cells leaked into brain ventricles during the transplantation (black dots in choroid plexus of the lateral ventricle). (B) More anterior view reveals selective dispersion of LGE-derived cells throughout the striatum (str). Notice the sharp boundary between the striatum and neocortex (ncx). (C) LGE-derived cells migrate also into the nucleus accumbens (na) and olfactory tubercle (ot) in the basal forebrain. (D) High magnification of labeled cells in the olfactory tubercle reveals multiple processes extending from individual cells. (E) In several animals, labeled LGE cells migrated into the core of the olfactory bulb (ob).
