Axonal growth by newly-formed vomeronasal neurosensory cells in the normal adult mouse.

Vomeronasal neurosensory cells which are continuously formed in adult mice have been shown to possess axons running in the vomeronasal nerves, since they undergo a reaction of retrograde cell death after vomeronasal nerve transection. Retrograde axonal transport of horseradish peroxidase has been combined with [3H]thymidine labelling of dividing cells to show that the axons of the newly-formed neurosensory cells reach their appropriate target, the accessory olfactory bulb.
