..., Msgn1 alone controls PSM differentiation by directly activating the transcriptional programs that define PSM identity, epithelial-mesenchymal transition, motility and segmentation. Forced expression of Msgn1 in NM stem cells in vivo reduced the contribution of their progeny to the neural tube...

... published ( Noguera-Troise et al.,2006 ; Ridgway et al.,2006 ). However this may be, our data indicate that Dll4-Notch signalling provides a way to halt endothelial motility and to downregulate endothelial proliferation in a coordinated way once the endothelial cells have become linked together...

...Stephan Wacker; Anja Brodbeck; Patrick Lemaire; Christof Niehrs; Rudolf Winklbauer ABSTRACT By comparing cells with respect to several motility-related properties and the ability to migrate on fibronectin, three cell types can be distinguished in the Xenopus gastrula. These occur in a distinct...

... and Gerhart, 1995 ), making it unlikely that the cells could still retain any detailed spatial pattern of progressive behavior imposed on them many stages earlier. Although general properties of the mesoderm may be induced in the blastula stage, the detailed patterns of motility and differen-tiation must...
