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 ...

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 ...

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 gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

When does your baby develop a heartbeat? A baby's heartbeat (at this point a fluttering of cells) starts as early as to 4 weeks after conception or 6 weeks after the first day of the last menstrual ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

Aitor Aguirre receives funding from the NIH, AHA, Corewell-MSU Alliance Foundation and HVI. Aleksandra Kostina and Brett Volmert do not work for, consult, own shares in or receive funding from any ...
