BEIJING -- After years of dedicated research, a team of Chinese scientists has unveiled critical mechanisms governing early human embryonic development, offering novel theories and potential ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

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 ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

The biological and legal definitions of “embryo” don’t match, and that will become a problem, according to Nicolas Rivron, PhD, of the Institute of Molecular Biotechnology of the Austrian Academy of ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of ...

Research published in Human Reproduction**,Europe's leading journal of reproductive medicine, has shown that, in mice, stimulating the ovaries by hormone drugs to produce more eggs appears to impair ...

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 ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...
