By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Embryos and the uterus exchange molecular signals within the first hour, shaping whether implantation succeeds or fails.

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy.
