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 ...

Optical coherence tomography (OCT) has emerged as a pivotal non‐invasive imaging modality in the study of embryonic development. By harnessing light to capture high-resolution, three‐dimensional ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

Now, a new study reveals that this pivotal step in human development is guided by a precise interplay between chemical signals and physical forces. Published in Cell Stem Cell, the paper introduces a ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

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 ...

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 ...

Scientists at EPFL have created a scalable 3D organoid model that captures key features of early limb development, revealing ...

After fertilization, embryos race through rapid cell divisions before slowing down to build specialized cells that will carry out distinct functions in the developing body—but the signals that trigger ...
