Cover legend

Two possible models for Xenopus gastrulation movement. The Regression Model (upper panel): the presumptive head region is specified first at the onset of gastrulation and then axial mesoderm is formed toward posterior. The Progression Model (lower panel): the chordamesoderm is progressively formed toward anterior and the head rudiment is specified at mid to late gastrulation stage. For details, see the article by Koide et al. in this issue.
