The expression intensity of the markers was similar for the merged data and the original dataset for the cell populations identified with either the pan-tumor panel (fibroblasts and EpCAM+FOLR1+CD24+tumor cells) or the pan-immune panel (Tregs and CD8+T cells [EMRA: terminally differentiated effector memory cells re-expressing CD45RA]) (Addendum 1). The gene discussed is FOLR1; the disease is neoplasm.
