Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

Bangkok — Scientists have developed human embryo-like structures without using sperm, an egg or fertilization, offering hope for research on miscarriage and birth defects but also raising fresh ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...

Cambridge University researchers developed the world’s first synthetic human embryo models using stem cells but without using an egg or sperm, which has sparked ethical concerns and questions about ...

(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings. Even if transplanted into a ...

When someone says the word embryo, what do you think of? Probably that picture you’ve seen a thousand times on a thousand different news articles: a translucent orb swelling with cytoplasm being ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

Central to many of the bioethical issues of our time is the question, When should society confer moral status on an embryo? When should we call an embryo or a fetus one of us? The fertilized egg ...
