Extended Data Fig. 4: Olig2 Expression in Graft.

(A) Olig2-expressing cells (oligodendrocyte progenitors and both immature and mature oligodendrocytes) were distributed throughout grafts, comprising 9 ± 2% of total grafted cells. NeuN labeling shown in blue. (B) Confocal image of four Olig2+ cells (arrows) in the graft. DAPI labeling shown in gray. See Methods regarding sampling methods and reproducibility. Scale Bars: A, 100 µm; B, 10 µm.
