A recent study from the Francis Crick Institute in London has taken a key step in explaining how the human body takes shape in its earliest stages. The researchers behind the study focused on modeling the formation of the spine and notochord, a slender, rod-like structure that acts as a kind of GPS for a developing embryo. The notochord sends signals to surrounding cells, guiding them on where to move and what type of tissue to develop into. Together, these structures lay the foundation for t...
