In a groundbreaking advancement, scientists at Stanford University have developed a method to mass-produce identical mini human brains, known as brain organoids, utilizing a common food additive. This innovation equips researchers with the ability to study brain development and disorders on a larger scale, offering new possibilities for understanding and addressing conditions like autism and schizophrenia.
For over a decade, Stanford’s Brain Organogenesis Program has been at the forefront of brain research, growing three-dimensional brain-like structures from stem cells in the lab. These structures, which include neural organoids and assembloids, have provided researchers with novel insights into the complexities of brain development. However, a significant challenge has been producing these organoids in large, consistent batches due to their tendency to clump together.
The solution emerged when researchers discovered that xanthan gum, a widely used food additive known for its thickening properties, could prevent these organoids from sticking together. This simple yet effective solution enables the production of thousands of uniform organoids, thus exponentially increasing the scale of testing and research. The success was spearheaded by Sergiu Pasca, a renowned professor of psychiatry and behavioral sciences, in collaboration with Sarah Heilshorn, a professor of engineering.
This accomplishment facilitates rapid drug screening and further exploration of brain disorders. Demonstrating the practical impact of their technique, the team evaluated the side effects of nearly 300 FDA-approved drugs on brain development, identifying several drugs that may potentially be harmful.
The implications of this discovery are extensive. By making it possible to produce large quantities of organoids, researchers can more effectively study complex neurodevelopmental disorders and test new therapies, potentially leading to breakthroughs in the treatment of conditions that have long been challenging to address.
