Higher level of Sr-exosomal PD-L1 in OS patients with pulmonary metastasis compared to ones without metastasis. a–d Radiological images of four OS patients with and without pulmonary metastasis. e Western blot analysis revealing significant difference for Sr-exosomal PD-L1 level in serum exosomes derived from patients with and without pulmonary metastasis; f ELISA analysis showing higher level of exosomal PD-L1 in serum of pulmonary metastasis patients compared to ones without metastasis
