[Retracted] Adipose-Derived Mesenchymal Stem Cell-Derived Extracellular Vesicles Rescue Tendon Injury in Rat via the miR-19 a/IGFBP3 Axis

Figure 3

ADSC-derived EVs inhibited oxidative stress and promoted proliferation of tendon cells. (a) TEM was used to observe the structure of EVs (scale: 100 nm). (b) DLS was used to observe the particle size of EVs. (c) Western blot was used to detect the markers of EVs. (d–g) ELISA was used to detect the levels of CK, LDH, MDA, and SOD in the control group, injury group, and injury+EVs group. (h) MTT was used to detect the activity of tendon cells. (i) FCM for the detection of the apoptosis of tendon cells. (j) The expression of apoptosis-related proteins was detected by Western blot (, , and ).
