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 ...

Advances in genetic and computational tools have enabled researchers to study complex networks of gene expression in individual cells, and the patterns of gene expression in a population of cells ...

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 ...

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many ...

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 ...

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 ...

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 ...

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 ...

Last year, researchers identified the early origins of neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- in chick embryos. Now the ...
