Lab grown models of embryos, made from clusters of stem cells, are getting increasingly complex. Ethicists, regulators and ...

The embryos were created in 1994, while the expectant father was still a toddler, and donated via a Christian “embryo adoption” agency.

NEW YORK (Reuters Health) - Scientists have discovered what might be the first crucial step needed for an embryo to take up residence in the womb--a finding experts say could ...

While the impact of embryo quality on miscarriage risk has been extensively studied, the endometrium (the womb lining) has largely remained a missing "black box" in reproductive medicine.

Once the eggs mature into embryos, they can be either transferred to the uterus or frozen via the IVF embryo freezing process. Embryos frozen by vitrification, which involves freezing the embryo ...

Forget sperm meets egg. Using human stem cells, scientists have created human embryo-like structures inside petri dishes. These lab-grown blobs develop multiple structures that mimic a human embryo ...

A model of the post-implantation human embryo derived from pluripotent stem cells. Nature, 2023; DOI: 10.1038/s41586-023-06368-y ...

Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study.
