A snail tale and the chicken embryo

ABSTRACT Some 25 years ago, a clone was identified that contained the chicken Slug sequences (now called Snail2 ). How could we anticipate at that time how much the chick embryo would help us to understand the ins and outs of cell migration during development and in disease? Indeed, the chick embryo helped us identify Snail2 as the first transcription factor that could induce the epithelial-mesenchymal transition (EMT), key for the migration of embryonic and cancer cells.
