By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells that give rise to tissues such as the gut and lungs—originate from multiple ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

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 ...

Researchers say they have developed a noninvasive method to better predict the quality of embryos created through in vitro fertilization — they hope it makes it easier to get pregnant. “Unfortunately, ...

Going through the IVF process usually entails going through many complicated steps, and controlled ovarian hyperstimulation ...
