During embryonic development of the mammalian telencephalon, expressions of the Notch ligand: Delta like1 (Dll1), Hes1 and the proneural gene Neu- rogenin 2 (Ngn2) are oscillating in neural progenitors, being sustained ...

During vertebrate embryogenesis, the rhythmic and sequential segmentation of the body axis is regulated by an oscillating genetic network termed the segmentation clock. We describe a new dynamic model for the core pace-making ...
