Exosomes were isolated from the media of BMDMs (BMDMs-exo), BMDM-polarized M2 macrophages (M2-exo), BMDM-polarized M2 macrophages transfected with si-CRNDE (M2-si-CRNDE-exo), and BMDM-polarized M2 macrophages transfected with the negative control of si-CRNDE (M2-si-control-exo). (A) LncRNA CRNDE expression in indicated exosomes was detected by qRT-PCR. Data information: The results shown are from three biological replicates. Data are expressed as mean ± SD. : one-way ANOVA. **P<0.01.
