Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

The point when human embryonic stem cells irreversibly commit to becoming specialised has been identified by researchers at the Francis Crick Institute. Our biological history can be traced back to a ...

Huntington's disease is a neurodegenerative disorder that's caused by mutations in the huntingtin gene. People can be diagnosed early in life with a genetic test, but otherwise, the signs of the ...

Stem cells can self-renew and differentiate into a wide variety of cell types, making them critical components in embryonic development. In adults, stem cell populations, such as those in the ...

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 ...

Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...

Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...

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 ...
