Figure 6. Acute damage of RGCs induces the expression of Lif via Wnt/β-catenin signaling in Müller cells. Quantitative real-time RT–PCR for (A) Lif, (B) Edn2, and (C) Fgf2 in RNA from retinas of 8-week-old Slc1a3-Cre^ERT/Ctnnb1^fl/fl mice and Ctnnb1^fl/fl controls 7 h after injection of 3 µl of N-methyl-D-aspartate (NMDA; 10 mM) or PBS into the vitreous cavity and tamoxifen treatment 2 weeks before (mean ± standard error of the mean, SEM; *p<0.05; ***p<0.001).
