Artificial human life could soon be grown from scratch in the lab, after scientists successfully created a mammal embryo using only stem cells.
Cambridge University mixed two kinds of mouse stem cells and placed them on a 3D scaffold. After four days of growth in a tank of chemicals designed to mimic conditions inside the womb, the cells formed the structure of a living mouse embryo.The breakthrough has been described as a ‘masterpiece’ in bioengineering, which could eventually allow scientists to grow artificial human embryos in the lab without the need for a sperm or an egg.
