The emergence of multicellular life roughly 700 million years ago was a pivotal event that shaped the evolution of life on ...

Scientists have reprogrammed mouse cells into pluripotent stem cells using a gene from choanoflagellates, single-celled ...

The research highlights how evolution repurposes existing genetic tools, turning them into versatile drivers of innovation.

An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of ...

We all start our lives as symmetric balls of cells. In humans, during the first few weeks after fertilization, embryonic ...

Scientists at Queen Mary University of London and the University of Hong Kong have created a mouse with substituted genes ...

but not extra-embryonic tissues such as the placenta. Substrates with concave curvatures resembling those found in the developing embryo mechanically revert mouse and human pluripotent stem cells ...

At left are images taken from two different embryonic stem cell (ESC) cultures—see red arrows—one from mouse (left) and the other from human (right). Both mouse and human ESCs form compact ...

Takahashi, K. & Yamanaka, S. Induction of pluripotent stem cells from mouse embryonic and adult fibroblast cultures by defined factors. Cell 126, 663–676 (2006).

Neuronal stem cells produce a variety of nervous system tissue, mostly during early embryonic development but ... spread them out on a feeder layer of mouse cells to produce an immortalized ...

The result is a hormone-rich carpet of mouse cells upon which a few human embryonic stem cells are finally placed. There they live like pampered pashas. If their scientist-servants don't feed them ...
