New Research Suggests Stem Cells Delivered Intranasally Improve Motor Function in Parkinson’s Disease

Using a rat model of Parkinson’s disease, new research published in the journal Rejuvenation Research demonstrated that stem cells delivered intranasally survived for at least six months in the brain, that the stem cells rapidly migrated preferentially to the damaged areas of the brain, and that motor control showed significant improvement.

Researchers theorized this likely occurred because of the demonstrated anti-inflammatory and neuroprotective effects of the stem cells, which were derived from bone marrow.

Study authors concluded that intranasal administration of stem cells to the human brain is a promising and noninvasive alternative to current surgical procedures. It also opens up the possibility of chronic stem cells treatment, which would increase the number of cells delivered to the brain and likely enhance the therapeutic benefit.

This research was funded by the Alzheimer’s Research Center, a nationally recognized research hub conducting studies on Alzheimer’s, Parkinson’s disease, and other neurodegenerative disorders.
