Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells ...

STORY: This looks a lot like a human embryo. But it was created without sperm, eggs, or a womb. It was made in a lab, by a group of scientists in Israel. And what they've created so far offers a new ...

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 ...

It’s still one of the biggest mysteries in science: How does a human cell — too small to see with the naked eye — divide and reproduce to ultimately become a human body made up of more than 30 ...

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 ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

Harvard scientists have discovered new evolutionary changes in pelvic structure that allowed the first humans to walk upright ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Ali Brivanlou slides open a glass door at the Rockefeller University in New York to show off his latest experiments probing the mysteries of the human embryo. "As you can see, all my lab is glass — ...

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 ...

This study provides valuable insights into human valve development by integrating snRNA-seq and spatial transcriptomics to characterize cell populations and regulatory programs in the embryonic and ...
