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 ...

Scientists set a new record for growing primate embryos outside the womb, as reported in the May issue of the journal Cell. For the first time, monkey embryos were cultivated in a lab for 25 days post ...

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 ...

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells ...

Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

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 ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...
