Figure 4From: The role of Serine Proteases and Serine Protease Inhibitors in the migration of Gonadotropin-Releasing Hormone neuronsA 1 μm optical section of an El 5 mouse embryo cut in the sagittal plane at the level of the vomeronasal organ (VNO). MAP1b immunoreactive axonal bundles (A, arrows) of the vomeronasal nerve are identified by FITC fluorescence; PN-1 immunoreactivity (B, arrows) by Texas Red fluorescence. All fascicles were double labeled. Scale bar= 100 μm.Back to article page
