Interactions between Dorsally and Ventrally Derived Oligodendroglia in the FFOs
(A) A schematic procedure for fusing the VFOs and DFOs that were respectively derived from isogenic OLIG2-GFP hiPSC reporter line and ND2.0 hiPSC line that do not have any reporter fluorescence.
(B and C) Representatives (B) and quantification (C) (n = 4 organoids) showing that ventrally derived OLIG2+ cells (GFP+) are outnumbered by dorsally derived OLIG2+ cells (GFP-negative) at 1 week after fusion (week 10) to 6 weeks after fusion (week 15). Student's t test: ∗∗∗p < 0.001. Scale bar, 100 μm.
(D and E) Quantification (D) and representatives (E) showing MBP+ cells with a ventral (GFP+) or dorsal (GFP-negative) origin (n = 4 organoids). Student's t test: ∗∗∗p < 0.001. Scale bars, 50 μm.
