A team of researchers in the United States and the United Kingdom says they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm ...

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 ...

Seven years after the first gene-edited babies were revealed, biotech startup Manhattan Genomics is reviving the idea of ...

Humans have long been able to create a human embryo via in vitro fertilization, or combining egg and sperm in a test tube and ...

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 ...

In the near term, researchers hope to use these so-called embryoids to better understand early stages of development and study mechanisms behind disease without the need for as many lab animals. The ...

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos. In June, ...

Only about one out of three conceptions leads to birth. 1 Approximately a third of embryos fail to attach to the uterus, while another third is lost after the embryo implants. “Human reproduction is ...
