Stem Cell-Based Nasal Spray Shows Promise in Reversing Brain Aging and Memory Loss
What Happened
Researchers at Texas A&M University developed an experimental nasal spray containing extracellular vesicles, tiny particles derived from stem cells, that reduced brain inflammation and restored memory in aging mice. After just two doses, the treatment improved cognitive function for months and helped reset key biological pathways linked to age-related brain decline.
Key Takeaways
The findings still in the preclinical stage and not yet tested as a treatment for people, the approach could eventually open new avenues for tackling dementia, Alzheimer's disease, and age-related memory loss.
