Dormant Stem Cells May Hold Key to Restoring Sense of Smell

Researchers have created a 3D mouse organoid model to study how neurons in the nose regenerate, revealing that a type of stem cell once considered dormant may be crucial for repairing olfactory tissue. The team found that horizontal basal cells (HBCs), marked by KRT5, actively support new neuron generation alongside globose basal cells (GBCs).
