Interestingly, comparison of our transcriptomic data with melanoma stromal scRNAseq data [42] showed that tdTomato+PDGFRα+ cells from Snail1ME-WT tumours were enriched in the signatures related to the S1 ("immune") and S2 ("desmoplastic") CAFs subpopulations (Fig. 2i). This evidence concerns the gene TBX1 and neoplasm.
