As an embryo grows, there is a continuous stream of communication between cells to form tissues and organs. Cells need to read numerous cues from their environment, and these may be chemical or ...

A crucial new mechanism that helps explain how the heart’s major blood vessels form during early development – and how disruptions to this process can lead to serious congenital heart defects – has ...

A team led by researchers at the University of Toronto has discovered that a group of cells located in the skin and other areas of the body, called neural crest stem cells, are the source of ...

An illustration of zebrafish heart development, showing the migration of cells in the growing embryo after 17 hours, 1 day and 2 days to form the heart. Most heart cells come from the embryonic ...

Scientists have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular 'bridge' complex demonstrate a new level of detail in the ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

The distinct aging rates of neural progenitor cells and Wnt signaling dictate mammalian cortical layer proportions.

Human-accelerated regions (HARs) are sections of the human genome that have accumulated an unusually high level of mutations as humans split away from chimpanzees. Given their rapid evolution, some ...

Biological cells process data and perform computations all the time. They take inputs in the form of external stimuli and produce specific responses. Recently, scientists have been looking at ways to ...
