Immunostaining for YTHDF3 (a, b), VIRMA (c, d); and m6A (e, f) in testicular germ cell tumors. a Strong YTHDF3 cytoplasmic immunoexpression in embryonal carcinoma; b Weak/moderate YTHDF3 cytoplasmic immunoexpression in postpubertal-type teratoma; c strong VIRMA nuclear immunoexpression in seminoma; d Weak/moderate VIRMA nuclear immunoexpression in Seminoma; e Strong m6A nuclear immunostaining in seminoma; f Weak/moderate m6A nuclear immunostaining in postpubertal-type yolk sac tumor. Note the granularity of staining, particularly in c, d and e
