Exosomes Play an Important Role in the Progression of Plasma Cell Mastitis via the PI3K-Akt-mTOR Signaling Pathway

Figure 1

The ultrastructure changes of PCM and exosomes extracted from normal and PCM tissues were observed by a transmission electron microscope. (a) More microvesicles were found in the synaptic cleft of PCM indicated with red arrows. (b) A representative transmission electron microscopy image of PCM/exo and N/exo, showing a typical “saucer-like” morphology (scale bar, 100 nm). (c, d) Analysis of exosome size indicated similar particle size distribution of PCM/exo and N/exo.
