Complement C3/ C3a expression in subretinal fibrosis. a The expression of C3 mRNA in the retina and RPE/choroid/sclera was examined by qPCR at 3- and 25-days post the second laser. Mean ± SEM. n = 4–6 eyes per group. *p < 0.05 compared to untreated controls. One-way ANOVA, Bonferroni corrected. b, c Cryosections from a mouse eye 30 days post two-stage laser model were stained for C3a (b), C3aR (red) and F4/80 (green) (c) and imaged by confocal microscopy. b C3a staining in the retina (arrows) and in the subretinal lesion (asterisk). c F4/80+C3aR+ macrophages within the subretinal lesion (yellow cells, arrows). ONL = outer nuclear layer, SRL = subretinal lesion. Scale bars = 100 μm.
