We started more broadly, merging scRNA-Seq datasets of BCC myeloid cells with myeloid cells (dendritic and macrophages) with other datasets that have examined the role of Trem2+ cells from different tissue contexts including normal skin, wounded skin, various cancers, and microglia (Supplementary Fig. 4a, b and Supplementary Data 4)22,23,30,32,33. This evidence concerns the gene TREM2 and skin basal cell carcinoma.
