HMSC-Derived Exosome Inhibited Th2 Cell Differentiation via Regulating miR-146a-5p/SERPINB2 Pathway

Figure 2

The HMSC-exo was able to uptake by AR CD4⁺ cells through endocytosis. The PKH67-labeled (green) immature HMSC-exos were cocultured with CD4⁺ cells. Then, the AR CD4⁺ cells were fixed and stained with DAPI (blue). The uptake of HMSC-exos by AR CD4⁺ cells was observed under a confocal microscope.
