Scientists have visualised the early development of the nervous system in a chicken embryo. Minyoung Kim at the University of California, San Francisco, dissected the 2-day-old embryo out of its egg ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

Around the time of gastrulation in higher vertebrate embryos, inductive interactions direct cells to form central nervous system (neural plate) or sensory placodes. Grafts of different tissues into ...

Successful embryonic development depends on a series of patterning and symmetry breaking events. Developmental patterning is often coordinated by organizers, specialized signaling centers that dictate ...
