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 ...

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 ...

Researchers at Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, demonstrate how morphogens combined with cell adhesion can generate tissue domains with a sharp boundary in an in vitro ...

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 ...

Many simpler forms of life on this planet, including some of our earliest ancestors, don't have proper brains. Instead they have networks of neurons that fire in response to stimuli, triggering ...

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 ...
