chicken embryo

Researchers study how oxygen around an embryo helps shape the way feet and digits form in amphibians and chickens.

Studying how neural crest cells journey through the embryo, this Caltech developmental biologist has revealed how they form major cell types, including peripheral neurons, bone, and smooth muscle.

To track distinct populations of developing cardiovascular cells, scientists used pulses of electricity to introduce fluorescently labeled DNA into chick embryos.

In a developing chicken embryo, skin cells pull on each other, forming multicellular mounds that eventually turn into properly-spaced feathers.

The skeleton of this 13-day-old chick embryo has been stained to highlight cartilage (blue) and bone (red).
