From: M2 microglia-derived exosomes promote vascular remodeling in diabetic retinopathy
M2-exo promotes revascularization and facilitates M2 polarization of microglia. A Validation of the ability of M2-exo to promote revascularization and M2 microglia polarization by immunofluorescence in OIR mouse (scale bar = 200 μm). B Retinal cell flow analysis demonstrates that M2-exo promotes M2-type microglial polarization. C Representative immunofluorescence images showing changes in primary microglia after treatment with PBS, M0-exo, and M2-exo. Scale bar = 20 μm
