Studying the shape of tissues and organs is critical to understanding how they are formed. Embryonic development happens in three dimensions, but many studies are limited by the use of two-dimensional ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Together with his student Hilde Mangold, the biologist Hans Spemann discovered the so-called »organiser« during embryonic development in 1924. In ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

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 ...

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 ...

New research tracks how cells prepare gene regulatory decisions that will define their fate during the earliest stages of ...

This allows researchers to use guinea pigs to investigate how early environmental changes, such as exposure to various chemicals or drugs, can affect embryo development and future health. "Guinea pigs ...
