Scientists have been able to make and study human embryos in their labs for decades. But they have never been able to keep them alive outside a woman's womb for more than about a week. That limitation ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A new study takes a tour of the history of research into human embryology and development to show the "cycles of attention" that led to major scientific breakthroughs. Analyzing the past sheds light ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

Truth matters. Community matters. Your support makes both possible. LAist is one of the few places where news remains independent and free from political and corporate influence. Stand up for truth ...

Stem cell-based embryo models (SCBEMs) are three-dimensional biological structures that mimic aspects of early human embryo development. They can be created in the lab from stem cells, and can provide ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

Microscopy image of a day 14 human embryo that has implanted in the new artificial womb. (Matteo Molè at the Babraham Institute.) Scientists have gotten an unprecedented look at how the human embryo ...

Rowan University biology professor Natasha Shylo is exploring left-right asymmetry development with a grant from the National Institutes of Health.

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...
