Exosomal miR-137-3p targets UBE3C to activate STAT3, promoting migration and differentiation into endometrial epithelial cell of human umbilical cord mesenchymal stem cells under hypoxia

Figure 3 miR-137-3p invigorated the signal transducer and activator of transcription 3 signaling cascade. Human umbilical cord mesenchymal stem cells were transfected with miR-137-3p mimic or negative control. A: Western blot analysis of p-protein kinase B and p-mitogen-activated protein kinase protein expressions; B: Western blot evaluation of p-signal transducer and activator of transcription 3 protein levels. The findings are presented as mean ± SD. AKT: Protein kinase B; MAPK: Mitogen-activated protein kinase; STAT3: Signal transducer and activator of transcription 3; NC: Negative control.
