Research team worked with mice that had been genetically modified to lose their sense of smell.
Basal cells naturally replace damaged and ageing neurons related to smell.
Basal cells developed into fully mature olfactory sensory neurons, stretching right into the brain.
Many questions would need to be worked out before using this cell-based therapy in a human patient.
