Alterations in the VNO of Mash1−/−mice. A, B, Sagittal sections through the VNO of an E18.5 Mash1+/+;Tattler-4+/−embryo (A) and aMash1−/−;Tattler-4+/− littermate (B) stained with X-gal. Anterior is on theleft, and dorsal is at the top.A, Sensory neurons in the VNO epithelium (arrowhead) stain with X-gal as do the vomeronasal nerves (arrows). B, The number of sensory neurons and the size of the VNO (arrowhead) as well as the size of the vomeronasal nerve (arrow) is reduced in the Mash1−/−;Tattler-4+/− littermate. Scale bar, 100 μm.
