An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness. When you purchase through links on our site, we may earn ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

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 ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...
