Signalling by bone morphogenetic proteins (BMPs) acts in a conserved all-or-none fashion to repress the expression of all neural genes in the epidermal ectoderm of bilaterian embryos. The ...

Scientists at St. Jude Children’s Research Hospital imaged cellular projections called cytonemes that transfer signals across long distances during development St. Jude Children’s Research Hospital ...

St. Jude Children's Research Hospital scientists found that cytonemes (thin, long, hair-like projections on cells) are important during neural development. Cytonemes connect cells communicating across ...

In the vertebrate neural tube, the morphogen Sonic Hedgehog (Shh) establishes a characteristic pattern of gene expression. Here we quantify the Shh gradient in the developing mouse neural tube and ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Subscribe to our newsletter for the latest sci-tech news updates ...

Scientists have developed an artificial neural network out of DNA that can recognize highly complex and noisy molecular information. Researchers at Caltech have developed an artificial neural network ...
