say they have used human cells from the lining of uteruses to create what they say can be called wombs on a chip and already use them to gain new insights into how human embryos implant in a womb.

Scientists hope their work will help more people have healthy babies, but the experiments raise many ethical concerns, including using human embryos for research and the possibility that someday the technology could enable babies to develop completely outside the human body.
