Scientists create replica human womb lining and implant early-stage embryos

Studying chemical chatter as tiny balls of cells embed could shine a light on early pregnancy and glitches that lead to miscarriage

Researchers have created the lining of a womb in a dish, which promises to shed light on the mysterious early stages of human pregnancy and the glitches that can lead to miscarriage and medical complications.

In laboratory experiments, early-stage human embryos donated from couples after IVF treatment successfully implanted into the engineered lining and began to churn out key compounds, such as the hormone that results in a blue line on positive pregnancy tests.
