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

Figure 3 Immunofluorescence detection of β-III tubulin. A-C: Immunofluorescence staining of β-III tubulin (red) and nuclear staining (DAPI, blue) (left panel) and the number of β-III tubulin-positive retinal ganglion cells (right panel) in different groups after exposure to 40 mmHg (A), 80 mmHg (B), and 120 mmHg (C). ^aP < 0.05, compared with the normal control group (scale bar: 50 μm); ^bP < 0.05, compared with model (40, 80, and 120 mmHg) group. ADSC: Adipose-derived stem cell; BMSC: Bone marrow-derived stem cell; Exo: Exosome; NC: Normal control; CREB: Cyclic adenosine monophosphate response element-binding protein.
