Stem Cell–Derived Neurons from People with Autism Grow Differently – The Scientist

Neurons derived from the skin cells of people with and without autism spectrum disorder exhibit different patterns of growth and development, according to a study published this week (January 7) in Nature Neuroscience.

“Although our work only examined cells in cultures, it may help us understand how early changes in gene expression could lead to altered brain development in individuals with ASD [autism spectrum disorder],” coauthor Rusty Gage, president of the Salk Institute, says in a press release. “We hope that this work will open up new ways to study neuropsychiatric and neurodevelopmental disorders.”

Gage and his colleagues converted skin cells from eight people with ASD and five developmentally typical controls into induced pluripotent stem cells, then re-differentiated those cells into neurons. During that re-differentiation process, the researchers noticed differences between the two groups. For example, neurons derived from people with ASD grew faster and developed longer and more-complex branches than the other cells. As the cells grew into 3-D organoids, those derived from people with ASD were bigger.
