Additional scRNA-seq and flow cytometry data of DRG immune cells. (A) Epineurial macrophage signature (selected genes from Ydens et al. [2020]) across DRG immune cell types. (B) Ex vivo activation gene signature (25 genes identified in Marsh et al. [2022]) across DRG immune cell types. Induction of gene signature is most apparent in macrophages. (C) Conventional gating strategy to identify major immune cell populations in the UMAP. (D) Expression heatmap of all flow cytometry markers across UMAP clusters.
