Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4 th to 7 th day after fertilization. In normal embryonic ...

Scientists in the Brivanlou lab used light-inducible gene expression (yellow circle) and embryo models to demonstrate that, at the start of gastrulation, body-axis formation requires an interplay ...

A team of researchers in the United States and the United Kingdom says they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm ...

Researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery. As different as they may seem, ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...

A mature cell of one type can be turned into a mature cell of another type without the cell having to pass through an earlier stage of development. This is called direct reprogramming, a reliable but ...

An anti-aging gene discovered in a population of centenarians has been shown to rewind the heart's biological age by 10 years. The breakthrough, published in Cardiovascular Research and led by ...
