Intranasal stem cell therapy restores smell in mice

A stem cell therapy delivered into the nose can restore the sense of smell in a mouse model of olfactory loss. The findings, published May 30 in the journal Stem Cell Reports, provide proof of principle for an approach that ...

Why the sense of smell declines in old age

As mammals age, their sense of smell deteriorates. In a study published in the journal Cell Reports, an interdisciplinary research team at Helmholtz Zentrum M√ľnchen and the University Medical Centre Mainz investigated why ...

When the nose doesn't know: Can loss of smell be repaired?

Researchers at Tufts University School of Medicine, led by Dr. James E. Schwob, are examining the behavior of adult stem cells within the context of aging and, specifically, the sense of smell. As part of the normal aging ...

Neuroscience

Inflammation required for olfactory tissue regeneration

In a mouse study designed to understand how chronic inflammation in sinusitis damages the sense of smell, scientists at Johns Hopkins say they were surprised to learn that the regeneration of olfactory tissue requires some ...

Neuroscience

Distant brain regions selectively recruit stem cells

Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the University of Basel reports in the current issue of Science that long-distance brain connections ...

When neurons are 'born' impacts olfactory behavior in mice

New research from North Carolina State University shows that neurons generated at different life stages in mice can impact aspects of their olfactory sense and behavior. The work could have implications for our understanding ...

Missing piece surfaces in the puzzle of autism

A study carried out by the Laboratoire Neurobiologie des Interactions Cellulaires et Neurophysiopathologie (CNRS/Aix-Marseille Université), in collaboration with clinicians from Marseilles Public Hospitals (AP-HM) and scientists ...

Scientists sniff out unexpected role for stem cells in the brain

For decades, scientists thought that neurons in the brain were born only during the early development period and could not be replenished. More recently, however, they discovered cells with the ability to divide and turn ...
