An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Scientists have created a comprehensive "atlas" of what early embryonic development looks like in mammals, showcasing how a fertilized egg transforms into a complex organism with a distinctive shape ...

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 ...

The earliest stages of mammalian embryo development are like an orchestra performance, where everyone must play at the exact right moment and in perfect harmony. New research identifies one of the ...

The embryos cannot develop into humans, and are being used to study development in outer space.

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

NEW YORK -- New lab techniques have provided the first good look at a crucial but mysterious stage in the development of human embryos, scientists reported Wednesday. The researchers said follow-up ...

The Shenzhou-22 successfully made it back from China's space station on May 29. The cultured embryo material was among science samples brought back as part of a project undertaken by a research team ...
