Subpopulations of transplanted NSCs express functional neuronal proteins 7 days after cell transplantation. Grafted NSCs expressed Synapsin-1, GABA, PSD-95, MAP-2, ChAT and PGRN. Scale bars, 100 µm. GFP, green fluorescent protein; Hoe, Hoechst 33342; PSD-95, postsynaptic density protein-95; MAP-2, microtubule-associated protein-2; ChAT, choline acetyltransferase; PGRN, progranulin; GABA, γ-aminobutyric acid.
