Fig. 4. Transcriptional regulation of LGE development.(A) Unsupervised
clustering of human LGE postmitotic cells and gene expression patterns
visualized by t-SNE. Each dot represents an individual cell colored according
to the expression level (red, high; gray, low). (B) Developmental trajectory of
LGE cells visualized by UMAP. Pseudotime for individual cells is also shown
(top right). (C) Gene expression profile along the developmental trajectories
of LGE cells visualized via UMAP. (D) Volcano plot of DEGs for LGE cells
with OB and striatal potential. (E) Heatmap illustrating the bifurcation of
gene expression along the developmental trajectory of LGE cells committed to
OB and striatal fates. (FandG) The neuropeptide signaling pathway is
enriched in LGE cells with striatal potential. (H) Heatmap illustrating
DEGs enriched inTSHZ1+D1MSN,PDYN+ D1 MSNs, and D2 MSNs.
(I) Schematic of hypothetical genetic programs underlying the early
diversification of human LGE cells.
