No effect of genotype on the number of surviving Brn3a+ RGCs was observed in WT and Mmp2-/- animals at 14 dpi ONC + IS (Figure 2A–F), in line with that literature reporting that Mmp2 deficiency does not Italic naffect neuronal survival after retinal ischemia-reperfusion injury [39]. Here, POU4F1 is linked to retinal ischemia.
