Molecular comparison of macroglia subtypes. (A) Heatmap of top DEGs in macroglia subtypes that are grouped according to hierarchical clustering. Pairwise differential expression tests between macroglia subtypes were done to identify shared and unique gene signatures. Color represents z-scored expression. (B) Expression levels of transcription factors commonly associated with specific glia point to potential lineage relationships among known and novel macroglia subtypes. Values shown are log-normalized counts. (C) GO biological process terms associated with the top DEGs between OPC-A and OPC-B at 1 dpi. Div, dividing; Oligo, oligodendrocyte.
