In a laboratory in Israel, an incubator drum spins on a bench. The two glass bottles attached to the drum contain mouse embryos, each the size of a grain of rice, with translucent, pulsing hearts.

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 ...

Scientists have identified key molecular events in the developing human embryo between days 7 and 14 -- one of the most mysterious, yet critical, stages of our development. Scientists have identified ...

Many scientists today work in a laboratory environment designed to study the small things. Micropipette in hand, researchers slave for weeks, months, or years over a few microliters of solution that ...

Scientists have identified key molecular events in the earliest stages of human embryo development that could help shed light on why many pregnancies fail. These events occur in the second week of ...

"Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said Dr. Peter Rugg-Gunn, ...
