Figure 2: FMN2 is highly expressed in mossy fibers and is required for synaptic depotentiation. D. Representative low (upper panel, scale bar 500 µm) and high magnification images (lower panel) showing FMN2 expression (green) in FMN-EGFP knock in mice.For all experiments parasagittal brain slices from 14-21 day old mice were used. Cere, cerebellum; Hip, hippocampus, mf; mossy fiber, str. Luc.; stratum lucidum, cc, corpus callosum.
