Gastrulation is the first major morphogenetic movement during embryogenesis for forming the digestive tube.
Here we discuss recently obtained knowledge about the cellular events associated with formation of the notochord, namely cell division control, morphogenetic movement, and vacuole formation.
The morphogenetic movement of cells requires a positional cue from surrounding tissues to determine the direction of their movement by setting up the position of the migrating cells' filopodia or lamellipodia.
The tilting and fusion of the luminal pockets is not achieved by a simple expansion of the lumens, but rather requires a morphogenetic movement of the notochord cells that is dependent on the actin filaments.
coordination between cell division and morphogenetic movement is observed in the epidermal cells during neural tube closure (Ogura et al.
The cell fate decision, cell division, and morphogenetic movement of all cells constituting the ascidian larval body can be described at the single-cell level.
The recent studies introduced in the preceding sections clearly suggest that morphogenetic movement, cell cycle, and cell division are two key cellular events for understanding ascidian embryogenesis.
The coordination between the cell cycle and morphogenetic movement is not fully described in morphogenetic movement other than the epidermal cells during neural tube closure.
Ascidian Wnt-5 gene is involved in the morphogenetic movement of notochord cells.
