[Retracted] Adipose-Derived Mesenchymal Stem Cell-Derived Extracellular Vesicles Rescue Tendon Injury in Rat via the miR-19 a/IGFBP3 Axis
Figure 7
EVs rescued the tendon repair through promoting proliferation of tendon cells. (a) HE staining was used to detect tendon tissue. Base magnification: ×200. (b) Immunohistochemistry was performed to detect the expression of both PCNA and Caspase-3 in the tendon tissue. Base magnification: ×400. (c) The expression of apoptosis-related proteins was detected by Western blot in the control group, injury group, and injury+EV group (, ).
