Story summary

KTH Royal Institute of Technology researchers created an atlas of first-trimester heart development, published in Nature Genetics.
The atlas maps cell arrangements during fetal heart formation and highlights pacemaker and valves.
It identifies a group of adrenaline-producing cells that may influence heart responses under low oxygen.
Researchers urge study of heart development to understand congenital defects and improve prenatal care.
An interactive online tool is available for exploring the findings.
