Scientists used stem cells to create a model of an embryo in the lab without sperm or egg. The model embryo released the same hormones that trigger positive pregnancy tests. Researchers hope to use ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

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 ...

Scientists at the Weizmann Institute have achieved a scientific milestone by successfully creating a "complete" human embryo model entirely in the lab, without using sperm, eggs, or a womb, the BBC ...

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that occur before birth and why many pregnancies fail. These models are made from ...

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

A team of scientists in Israel say they’ve created a completely human-like embryo model without the need for a sperm or egg, up through 14 days of development. Reading time 3 minutes A team of ...

Some diseases begin in early development. To learn more about how they happen and how they might be treated, and to gain more insight into the basic biology of the human embryo, scientists have to use ...

A proposed international legal and ethical definition could address current challenges, with implications for improving IVF success rates. The ethical and legal challenges posed by embryology research ...
