(A–F) Representative immunohistochemical staining of transplanted iE3/3 and E4/4 neurons for HNa (A and D), NeuN (B and E), and human SYN (C and F). Scale bar, 25 μm.
(G and H) Representative immunohistochemical staining for mCherry+ (red) displayed distal projections emanating from the transplant core (G) (scale bar, 500 μm), with a magnified image of the inset (H) (scale bar, 50 μm).
(I) Whole-cell patch-clamp recordings in ex vivo slices of transplanted iE3/3 neurons (left) and E4/4 neurons (right) demonstrating capability to fire action potentials.
(J) Whole-cell patch clam recordings in ex vivo slices of transplanted iE3/3 neurons (top) and E4/4 neurons (bottom) demonstrating capability to receive sPSCs. Holding potential is −70 mV.
