Olfactory neurons are cells in the nasal cavity with the ability to regenerate, responsible for perceiving odors and passing the information along to the brain.  They project axons to the olfactory bulb within the brain itself with olfactory ensheathing cells surrounding the growing axons, assisting in their regeneration. The ability of olfactory ensheathing cells to promote neural regeneration has led to studies of their potential … Continue reading Genetically-engineered olfactory cells successfully bypass the BBB to kill brain cancer tumors.
