Stem cell stimulation shows promise as a potential noninvasive stroke treatment, according to research in mice published in JNeurosci. If extended to humans, this technique could greatly improve patients' quality of life.
Ling Wei, Shang Ping Yu, and colleagues at Emory University injected neural stem cells into the brains of mice after a stroke and activated the cells through nasal administration of a protein. The stem cells activated by this new, noninvasive technique called optochemogenetics grew healthier and formed more connections compared to the stem cells that did not receive stimulation. Additionally, the mice that received both stem cells and stimulation displayed the most recovery, with some behaviors returning to pre-stroke levels.
The combination of stem cell injection and stimulation increased the likelihood of a successful stroke recovery in mice. Instead of just injecting stem cells in the damaged area of the brain, following up with stimulation creates an ideal environment for the cells to develop and form connections with surrounding neurons.

JNeurosci, the Society for Neuroscience's first journal, was launched in 1981 as a means to communicate the findings of the highest quality neuroscience research to the growing field. Today, the journal remains committed to publishing cutting-edge neuroscience that will have an immediate and lasting scientific impact, while responding to authors' changing publishing needs, representing breadth of the field and diversity in authorship.
About The Society for Neuroscience
The Society for Neuroscience is the world's largest organization of scientists and physicians devoted to understanding the brain and nervous system. The nonprofit organization, founded in 1969, now has nearly 37,000 members in more than 90 countries and over 130 chapters worldwide.
