Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...

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 ...

SAN DIEGO - In what researchers describe as a historic step toward de-extinction science, an international team of gen ...

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 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 ...

Metabolism does more than fuel embryos—it sets their developmental rhythm. EMBL researchers found that a sugar molecule, FBP, controls the pace of spine formation, suggesting metabolism may act as a ...

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

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

People undergoing assisted reproduction view embryo transfer as their final step after completing an exhausting marathon. A ...
