From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop ...

The post Exciting Advancement In 3D Embryo Models Shows Lab-Grown Cells Making Their Own Blood Supply first on TwistedSifter.

Although the Human Genome Project announced the completed sequencing of 20,000 human genes more than 20 years ago, scientists are still working to grasp how fully formed beings emerge from basic ...

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 groundbreaking experiment transforms skin cells into egg-like cells, offering hope for infertility treatments amidst ethical considerations.

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 ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

WASHINGTON (AP) — Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. But the experiment ...

~ Scientists said the advance does not mean research involving getting stem cells from human embryos should be abandoned. NEW YORK -- In a leap forward for stem-cell research, three independent teams ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

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 ...
