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 ...

The rapid increase in global meat demand has placed significant pressure on traditional meat production. This has led to the emergence of the cultured meat industry as a promising alternative offering ...

The selection of high-quality embryos is essential to enhance the implantation rate for in vitro fertilization (IVF). Optical coherence microscopy (OCM) can noninvasively provide three-dimensional (3D ...

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

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 ...

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

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 ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...
