An advanced human heart organoid system can be used to model embryonic heart development under pregestational diabetes-like conditions, researchers report. The organoids recapitulate hallmarks of ...

Scientists at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences have developed a multi-chamber organoid that mirrors the heart’s intricate structure. The human ...

Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...

Researchers have developed a new software tool that provides unprecedented capabilities to see inside 3D images. Its interactive, dynamic cutaway views allowed them to analyze never-before-seen ...

Congenital heart defects are the most common form of human birth defect, but we still don’t fully understand what causes them. Previous research had suggested that some heart defects could be ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Monozygotic twinning itself after elective single embryo transfer is uncommon, occurring in no more than roughly 3% of cases.

This video shows a 3D confocal reconstruction of an organoid surface, showing blood vessels in green and cardiomyocytes in red. Blue is cell nuclei. An advanced human heart organoid system can be used ...
