Effects of Intensive Glycemic Control on Serum Exosome miR-126-3p and miR-125b-1-3p Levels and Wound Healing in Patients with Diabetic Ulcers

Figure 2

Exosomes identification results. Under the TEM, the double-layer membrane structure can be identified, which is an elliptical vesicle with a diameter between 30 and 150 nm (a). NTA shows that the peak size of the particle size is around 122.2 nm, and the concentration is 3.0 × 106/mL. The particle size of this size accounts for 97.8% of the ratio (b). In patients with diabetic ulcers, the protein bands of serum exosome surface markers CD63, CD9, and TSG101 were all positive before and after treatment (c).
