Turning human stem cells into brain cells sheds light on neural development
Date:5/2/2013

er. Those interactions, Anderson added, allowed the study team to observe cell-to-cell signaling that occurs during forebrain development.

In ongoing studies, Anderson explained, he and colleagues are using their cell model to better define molecular events that occur during brain development. By selectively manipulating genes in the interneurons, the researchers seek to better understand how gene abnormalities may disrupt brain circuitry and give rise to particular diseases. Ultimately, those studies could help inform drug development by identifying molecules that could offer therapeutic targets for more effective treatments of neuropsychiatric diseases.

In addition, Anderson's laboratory is studying interneurons derived from stem cells made from skin samples of patients with chromosome 22q.11.2 deletion syndrome, a genetic disease which has long been studied at The Children's Hospital of Philadelphia. In this multisystem disorder, about one third of patients have autistic spectrum disorders, and a partially overlapping third of patients develop schizophrenia. Investigating the roles of genes and signaling pathways in their model cells may reveal specific genes that are crucial in those patients with this syndrome who have neurodevelopmental problems.
