The DC2 subpopulation was subdivided into three subpopulations/states DC2_AREG (n = 2044), enriched in tumors and lymph nodes, DC2_FCER1A (n = 726), found mostly in the blood (Fig. 2c–f and Supplementary Fig. 3a,b), and a subpopulation expressing CD207, a langerin protein encoder (DC2_CD207, n = 505), which was abundant in tumor samples, particularly in lung and ovarian tumors and lymph nodes (Fig. 2e and Supplementary Fig. 3b,c). Here, CD207 is linked to ovarian neoplasm.
