Scientists have created the miracle of life — no male or female necessary.
It could have gone on to develop a spine, intestines and muscle — and, eventually, become a live mouse.
“Our mouse embryo model not only develops a brain, but also a beating heart, all the components that go on to make up the body,” said lead author and professor, Magdalena Zernicka-Goetz Any and all cells — liver cells, skin cells, blood cells, etc. — begin as stem cells but soon differentiate in the embryo in order to build a complete living organism. That’s why they’re often referred to as “master” cells. As the embryo develops, some stem cells will manifest into organs, bones and other tissues, while others multiply into “daughter” cells that the body stores for later — like, say, when we get an injury and need to generate new tissue for healing.
What Cambridge researchers observed in just over a week could be invaluable considering the estimated 20% to 50% of pregnancies end in miscarriage.Scientists are a long way off from creating a living, breathing body entirely inside the lab, and without input from a mother and father, but that’s not what this study is about.
