Building A Better Brain-in-a-dish, Faster and Cheaper

 In recent years, the development of in vitro human organoids -- three-dimensional, miniaturized, simplified versions of an organ produced from reprogrammed stem cells -- have allowed scientists to study biological functions, diseases and treatments more realistically and in greater detail.

 

"And that includes the brain," said Alysson R. Muotri, PhD, professor in the UC San Diego School of Medicine departments of Pediatrics and Cellular and Molecular Medicine, director of the UC San Diego Stem Cell Program and a member of the Sanford Consortium for Regenerative Medicine. "Cerebral organoids can form a variety of brain regions. They exhibit neurons that are functional and capable of electrical excitation. They resemble human cortical development at the gene expression levels."
