Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

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 ...

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 ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

NEW YORK -- Scientists say they have produced embryos that are clones of two men, a potential step toward developing scientifically valuable stem cells. It's the first documented demonstration that ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...
