STORY: This looks a lot like a human embryo. But it was created without sperm, eggs, or a womb. It was made in a lab, by a group of scientists in Israel. And what they've created so far offers a new ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...

Scientists have created models of human embryos by programming stem cells. The models give a glimpse into a key stage of development that can reveal new insights into genetic disorders and preventing ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

(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 ...

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 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 ...

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 ...

Four teams have coaxed human stem cells to organize themselves into embryo-like forms. The advance could shed light on fertility. By Carl Zimmer In its first week, a fertilized human egg develops into ...

Researchers are studying development of human pre-implantation embryos in an effort to improve success of embryo growth and development.
