CNIC researchers create virtual map of mammalian heart formation

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have developed a virtual map that reveals how the mammalian heart forms during early embryonic development. The heart is the first organ to form and begin functioning, and understanding this process may shed light on congenital heart defects. Source: infobae

How it was done

The team combined live microscopy of experimental models with advanced image analysis and machine learning to reconstruct the movements and shape changes that transform initial cardiac tissue into the primitive heart tube. The computational method tracks tissue movement directly from time-lapse images, validated by comparing with individual cell tracking. Source: diariolibree

Key findings

• Neighbouring cells move together in a coordinated manner, but different regions of the cardiac primordium have distinct movement and growth patterns. Source: infobae
• The initially bilateral primordium transforms into a longitudinal, three-dimensional heart tube. Source: diariolibree
• The map links the initial position of a cell or tissue region to its eventual contribution to the heart tube, offering a new way to explore how embryonic heart regions are organised over time. Source: infobae

Significance

"The main advance is that we can now describe heart tube formation in a quantitative way," said first author Morena Raiola. The map allows researchers to follow how each region of the initial cardiac tissue contributes to the primitive heart tube. This could help explain how alterations lead to congenital heart disease.
