FIGURE 5.  (A and B) Photomicrographs (original magnification, x400) of double fluorescence immunostaining using primary antibodies against GFP and GABA_A receptor in dorsal neocortex adjacent to cerebral infarct (A) and striatum (B) of BMSC-transplanted mice. Majority of GFP-positive cells express GABA_A receptor in dorsal neocortex adjacent to cerebral infarct (arrows) but not in striatum (arrows). (C) Photomicrographs (original magnification, x400) of double fluorescence immunostaining using primary antibodies against GFP and MAP2 reveal that majority of GFP-positive cells also express neuron-specific protein, MAP2, in dorsal neocortex adjacent to cerebral infarct (arrows) but not in striatum (data not shown).
