Biomedical Optics Express Release: First-Ever 3-D Stress Map of Developing Embryonic Heart Sheds Light on Why Defects Form

WASHINGTON--(BUSINESS WIRE)--As a human fetus develops, its heart has to keep pace with the new body’s ever-growing demands. Much of this is controlled by following genetic blueprints, but the embryonic heart also matures in response to the intense stresses of pumping blood. For the first time, researchers have been able to visualize in 3-D the stresses induced by flowing blood in an embryonic heart. The technique, which promises to provide new insight into how and why heart defects develop, is described in a paper published today in the Optical Society’s (OSA) open-access journal Biomedical Optics Express.
