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 ...

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 ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

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' ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

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

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 ...

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, ...

Cancers emerge from many different paths. One path begins early, in embryonic development, when a protein complex called PRC2 ...
