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

Figure 2

ADSCs rescued the tendon repair through inhibiting oxidative stress and promoting proliferation of tendon cells. (a) HE staining was performed in the control group, injury group, and injury+ADSC group (base magnification: ×200). (b) Immunohistochemistry detected the expression of PCNA and Caspase-3 in tendon tissues (base magnification: ×400). (c–f) ELISA was used to detect the levels of CK, LDH, MDA, and SOD in the control group, injury group, and injury+ADSC group. (g) MTT assay was conducted to detect the activity of tendons cells in the control group, injury group, and injury+ADSC group. (h) FCM was used to detect the apoptosis of cells. (i) The expression of apoptosis-related proteins was detected by Western blot (, ).
