Autism subgroups converge on cell growth pathway
Faulty mTOR signaling, implicated in syndromic forms of autism, also hinders cells grown from people with idiopathic autism or autism-linked deletions on chromosome 16.

Building a brain: How does it generate its exquisite diversity of cells?
High-throughput technologies have revealed new insights into how the brain develops. But a truly comprehensive map of neurodevelopment requires further advances.

Raising the bar for stem cell research: Q&A with Jack Mosher
New quality benchmarks for basic research involving stem cells promise to improve rigor and reproducibility, says Mosher, who helped develop the standards.

Autism’s ties to the cell skeleton
Many genes related to the condition play a role in the internal scaffolding of cells, and cytoskeletal disruptions can affect neurodevelopment and behavior.

‘Splice-switching’ strategy boosts SYNGAP1 expression
The approach improves the function of SYNGAP1-deficient neurons in vitro, but whether it will work in people remains unclear.

Autism-tied gene ZNF462 keeps developing neurons on track
The gene, linked to a little-known condition called Weiss-Kruszka syndrome, prevents embryonic stem cells from deviating from their neuronal destiny.

Autism and the cell’s antennae
Many autism-linked genes are somehow tied to cilia, the tiny hair-like sensors that stud a cell’s surface. But the question remains whether, and how, cilia differences contribute to the condition.
