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 ...

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 ...

Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...

The process of a single-celled zygote developing into a complex multicellular organism is precisely regulated at spatial and temporal levels in vivo. However, understanding the mechanisms underlying ...

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 ...

Germline-competent embryonic stem (ES) cells have been successfully derived from mice and rats, but not from other species. Here we report the development of culture conditions for deriving ES cells ...
