... repressor Pmar1. In this work, we identify several additional differences in the upstream regulation of the GRN during normal and regulative development. We provide evidence that, despite these changes in the upstream regulation of the network, downstream regulatory genes and key morphoregulatory genes...

..., activation of the skeletogenic GRN in NSM cells is independent of Lvpmar1 . Our studies reveal that, although most features of the micromere-PMC GRN are recapitulated in transfating NSM cells, different inputs activate this GRN during normal and regulative development. * Author for correspondence (e...

On this basis, classically defined phenomena such as regulative development and cytoplasmic localization can be interpreted at a mechanistic level, and the enormous differences between different forms of embryogenesis in the Animal Kingdom can be considered within a common...
