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

Figure 6

IGFBP3 promoted oxidative stress and inhibited proliferation of tenocytes. (a–d) ELISA was used to detect the levels of CK, LDH, MDA, and SOD in the pcDNA3.1 group, pcDNA3.1/IGFBP3 group, si-NC group, and si-IGFBP3 group. (e) MTT was used to detect the activity of tendon cells in the pcDNA3.1 group, pcDNA3.1/IGFBP3 group, si-NC group, and si-IGFBP3 group. (f) FCM was performed to detect the apoptosis of tenocytes. (g) The expression of apoptosis-related proteins was detected by Western blot in the pcDNA3.1 group, pcDNA3.1/IGFBP3 group, si-NC group, and si-IGFBP3 group (, , and ).
