Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

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

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...

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

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Monozygotic twinning itself after elective single embryo transfer is uncommon, occurring in no more than roughly 3% of cases.
