As a complementary approach to identify BCC-derived nerve-associated SCPs, we undertook single-cell transcriptomics to profile Prss56-Cre and Krox20-Cre-traced cells dissected from the dorsal and ventral roots at E11.5 and E12.5 (Fig. 3f and Suppl Fig. 2). Here, PRSS56 is linked to skin basal cell carcinoma.
