Later, animals—multicellular organisms—evolved, developing from a single egg cell to form complex beings. This embryonic development follows precise stages that are remarkably similar between ...

On June 23rd a Chinese team presented the most complete attempt yet. In a paper published in PNAS, a journal, they report ...

In animals, embryonic development starts when an egg cell is fertilized. This event triggers an array of consecutive cell divisions, known as cleavages. In a nutshell, ...

Males imprint their DNA by adding methyl modifications to it in a way that alters the activity of genes in order to promote ...

Zebrafish have the remarkable and rare ability to regrow and repair their hearts after damage. New research from Caltech and ...

Most animals, including humans, have bilateral symmetry, which means our bodies are pretty symmetrical. At least on the ...

Writing in Nature, Olivetta et al. 1 provide insights into how embryonic development arose in animals. Read the paper: A multicellular developmental program in a close animal relative.

Scientists were able to both activate genes at the beginning of the experimentation process and also modify genes important for other parts of development. This allows the embryo models to be ...

Cyborg tadpoles could provide new insights into brain development and help to understand diseases that manifest in early ...

The CRISPR programming not only allows the scientists to activate the genes at the beginning of the experimentation process, but also enables them to activate or modify genes important for other parts ...

Scientists have raised the first viable mouse with two male parents into adulthood after editing imprinting genes.

2025 will hopefully see a successful embryo transfer! CLOSE. ... The project has also made many achievements in giraffe embryo development, ... animals, conservation, embryo, in vitro fertilization, ...
