Human embryo cells used for scientific research are tightly controlled, but what if they’re not really … real? These are synthetic embryos. Scientists want to use them to understand better understand how humans are put together. || ✨Join Nebula and support me while watching this ad-free http://go.nebula.tv/tracedominguez, go watch “That Time When” Nebula Original: https://nebula.tv/thattimewhen?ref=tracedominguez
SYNOPSIS

Human embryos are a difficult thing for medical researchers to handle. They’re heavily regulated bits of human biology. Right now, any human embryos created for research have to be destroyed after 14 days unless they’re implanted inside a person. But once they’re in a person, it’s impossible to study them under a microscope! Researchers needed a solution. They mixed several different types of pluripotent stem cells with some chemicals, and let them self-form into these "new" synthetic embryos. Synthetic embryos can’t be implanted, and will never form a fetus, but they do behave very similarly to regular embryos and some researchers think they should be able to study them after the 14-day limit. What do you think? How did they make these? What does it all mean? Find out in this video.

Magdalena Zernicka-Goetz, Bren Professor of Biology and Biological Engineering at Caltech, and her colleagues have generated a human embryo–like model that mimics aspects of the second week of human development, a time after embryos become implanted in the womb.
