Metabolism does more than fuel embryos—it sets their developmental rhythm. EMBL researchers found that a sugar molecule, FBP, controls the pace of spine formation, suggesting metabolism may act as a ...

The role of Fibroblast Growth Factor 8 (FGF8) in embryonic development and organ formation is gaining increased recognition as scientists uncover its wide-ranging influence. FGF8, a powerful signaling ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Organoids are made to model human organs and are promising for research and therapy, but there are limitations in their growth and function. A recent study found that placenta-derived IL1 under ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

Scientists have pinpointed a stage in zebrafish embryo development where cells can better withstand disruptions to chromosome alignment during division. Using a light-activated tool to inhibit the ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...
