The development of body plans in all animals is controlled by a remarkably ... other genes that affect the positioning of cells in the embryo. While this sounds complicated, it is a far more ...

They have successfully grown human stem cells in a pig embryo. Why would anyone do this? Turns out, many scientists have been working on growing the organs of one animal inside of a different type ...

Genetic engineering in non-human primates has historically faced limitations due to the reliance on virus-based gene delivery methods.

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...
