Figure Lengend Snippet: Identification and uptake assay of AFs-derived exosomes. A Representative transmission electron microscopic photographs of AFs NPi -Exos and AFs HPi -Exos. The scale bar represents 200 μm. B The diameter distribution of AFs NPi -Exos and AFs HPi -Exos was detected by DLS analysis. C Western blot analysis of exosome-specific markers TSG101, CD9, and CD81 in exosomes secreted by NPi/HPi-induced AFs (AFs NPi -Exos, AFs HPi -Exos). D Representative images of AFs NPi -Exos and AFs HPi -Exos uptake by VSMCs after 12 h incubation. Nuclei stained by DAPI in blue and AFs-Exos stained by PKH26 in red. Scale bar: 50 μm
Article Snippet: After blocking with 5% non-fat milk for 1 h, the membrane was incubated overnight at 4 °C with primary antibody, including CD9 (ab92726, 1:1000, abcam), CD81 (ab109201, 1:1000, abcam), TSG101 (bs-1365R, 1:1000, bioss), Runx2 (ab23981, 1:2000, abcam), BMP2 (bs-10696R, 1:1000, bioss), GAPDH (10494-1-AP, 1:4000, proteintech), BMP4 (bs-1374R, 1:1000, bioss), Crim1 (bs-21654R, 1:1000, bioss), followed by incubation with the horseradish peroxidase-conjugated secondary antibody for 1 h at room temperature.
