Tucked within the nasal passages lies a quiet miracle — sensory neurons that can rebuild themselves across a lifetime, even as the world assaults them with viruses, toxins, and time. Researchers at Tufts University have now illuminated a hidden architect of that renewal: a population of stem cells long believed to be dormant, which turn out to be essential partners in regenerating the neurons that let us smell. Their discovery, built from a modest laboratory-grown tissue model, reframes how science understands olfactory loss — and points toward future treatments for the millions whose sense of

Consumers suffering from smell loss due to COVID-19, aging, or neurological conditions could gain access to new regenerative treatments, improving quality of life and potentially reducing healthcare costs associated with olfactory dysfunction complications.
FDA may need to establish regulatory pathways for stem cell-based olfactory therapies. Healthcare systems may expand coverage for olfactory loss treatments. Research funding agencies may prioritize olfactory regeneration studies given COVID-19 prevalence and aging populations.
