For the evaluation of the expression of FAP in MPM immunofluorescence (IF) microscopy was performed with the F19 antibody (A, C) or an irrelevant anti-CD20 antibody only (B, D). Epithelioid (A, B) and sarcomatoid (C, D) MPM were analyzed. FAP staining is depicted in green. Cell nuclei were stained with DAPI (blue).
