Expression pattern of PD-L1 in RMS. Comparable IHC results were obtained by PD-L1 clones SP124 and 22C3. (a and b) RMS16 showing a marked and consistent PD-L1-staining in the immune component IC3: staining visualized in areas surrounding and infiltrating the tumor burden. (c and d) RMS10 displaying a weak and focal staining of PD-L1, IC2, uniquely in the immune component encircling the tumor (as pointed out by the arrows). (e and f) An absent PD-L1 expression in all compartments, TC0 IC0: tumor and infiltrating immuno-component (RMS7). (g and h) H460, utilized as a positive control, reveals a marked expression in the tumor cells
