Detailed analysis of AG1. (A) Gene markers related with neurogenesis and neuronal development. Dark blue violin plots correspond to cell clusters of AG1 in individual samples (cx: cortex, sc:spinal cord). (B) Gene ontology enrichment analysis results of the significantly upregulated markers in AG1. (C) SEMA6 signaling pathway ligand-receptor components RNA expression across neuronal clusters and AGs. (D) SEMA6 cell-cell communication network analysis between neuronal clusters and AGs. The only AG actively communicating is AG1. (E) Heatmap of the SEMA6 signaling pathway and the role in the communication of the different neuronal and AGs.
