Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Why doesn’t a ‘good’ embryo always lead to pregnancy in IVF? Explore key factors beyond embryo quality that affect IVF ...

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 at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

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 ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...
