Figure 6

Developmental expression of Amgalaxin-like 2. There is no expression in the planula larva (A-B). Expression first appears as a ring on the aboral side of the planula as it shortens to form a sphere (C-D). Expression continues aborally, sometimes in a zone (E) and sometimes in a submarginal ring (F-J) as the polyp ages. In (F)(H) and (J) the polyp is viewed orally and the aboral expression is seen through the cleared tissue.
