Fig. 7From: Human adipose tissue-derived stem cell extracellular vesicles attenuate ocular hypertension-induced retinal ganglion cell damage by inhibiting microglia- TLR4/MAPK/NF-κB proinflammatory cascade signalingADSC-EVs decrease microglia-associated TLR4 expression in the OHT mice 2 weeks after injection. (A) Representative retina immunostaining and quantification of the expression of Iba-1 and TLR4 (n = 6, **p < 0.01, ***p < 0.001). (B) Representative optic nerve immunostaining and quantification of the expression of TLR4 and Iba-1 (n = 5, *p < 0.05, **p < 0.01, ***p < 0.001)Back to article page
