Scientists create a ‘mini-womb’ 3D model on a microfluidic chip which could lead to treatments for women affected by ...

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

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 ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Ancient DNA is turning human evolution into a crime scene reconstruction, and one of the prime suspects is a herpesvirus that ...

LONDON, Sept 20 (Reuters) - British scientists have used a genome editing tool known as CRISPR/Cas9 to knock out a gene in embryos just a few days old, testing the technique's ability to decipher key ...

Clear rules governing human embryo research must be established to enable regulators, researchers and funders to assess whether stem cell-generated models should be considered as human embryos, two ...

Scientists have invented a device that can quickly produce large numbers of living entities that resemble very primitive human embryos. Researchers welcomed the development, described Wednesday in the ...
