Kobe University Creates Stem Cell Bank to Study Autism Spectrum Disorder
Updated June 14, 2025
researchers at Kobe University have developed a bank of 63 mouse embryonic stem cell lines, each containing genetic mutations strongly linked to autism spectrum disorder. This resource aims to facilitate the study of genetic causes and potential drug targets for the condition. The team achieved this by creating a more efficient method for altering the genome of embryonic stem cells, a critical step in modeling the disorder.
While the influence of genetics on autism spectrum disorder is well-established, pinpointing specific causes and mechanisms has remained a challenge. Scientists use cell and animal models to understand the biological underpinnings of diseases. Cell models reveal how genetic changes affect cell function, while animal models demonstrate the impact on health and behavior. Despite differences, disease-causing genes often exhibit similarities across species.
TAKUMI Toru, a neuroscientist at Kobe University, noted the lack of standardized models for studying autism spectrum disorder mutations. “One of the problems, though, is the lack of a standardized biological model to study the effects of the different mutations associated with autism spectrum disorder. This makes it difficult to find out, for example, whether they have common effects or what is specific to certain cell types,” Takumi said.
Over 12 years, takumi’s team combined conventional mouse embryonic stem cell manipulation with the CRISPR gene editing system. This approach allowed them to efficiently create genetic variants and establish the stem cell bank. The team was able to develop these cells into various cell types and even generate adult mice with the genetic variations. Analysis confirmed the cell lines as adequate models for studying autism spectrum disorder, enabling large-scale data analyses to identify abnormally active genes and affected cell types.
Data analysis revealed that autism-causing mutations often impair neurons’ ability to eliminate misshapen proteins. ”This is especially interesting since the local production of proteins is a unique feature in neurons,and a lack of quality control of these proteins may be a causal factor of neuronal defects,” Takumi explained.
What’s next
Takumi anticipates that this resource, available to other researchers, will prove invaluable for autism research and drug finding. He also noted that the studied genetic variants are implicated in other neuropsychiatric disorders, such as schizophrenia and bipolar disorder, suggesting broader applications for the stem cell library in studying neuropsychiatric disorders.
