ADSC-Exos outperform BMSC-Exos in alleviating hydrostatic pressure-induced injury to retinal ganglion cells by upregulating nerve growth factors

Figure 5 Immunofluorescence detection of p-CREB and CREB. A-C: Immunofluorescence staining of CREB (green), p-CREB (red) and nuclear staining (DAPI, blue) (left panel) and quantification of the ratio of p-CREB/CREB (right panel) in different groups after exposure to (A) 40 mmHg, (B) 80 mmHg, and (C) 120 mmHg (Scale bar: 20 μm). ^aP < 0.05, compared with the normal control group; ^bP < 0.05, compared with the model (40, 80, and 120 mmHg) group. ADSC: Adipose-derived stem cell; BMSC: Bone marrow-derived stem cell; Exo: Exosome; NC: Normal control.
