Model of cell delamination in the midbrain and trunk. There are two waves of cell delamination and these cells adopt distinct cell fates in the midbrain of both mouse (A) and chicken (B) embryos. In the trunk, cells only delaminate when the neural and non-neural ectoderm are already separated (C). EC, non-neural ectoderm; NE, neural ectoderm; S, region where cells delaminate.
