(A) Basic process of apical junction rearrangement. The cells are labeled with NE, left SE or right SE to show that apical cell rearrangement similar to the one shown in A can be seen during the zippering shown in B. The shrinkage of NE/SE junction (inward double-arrowheads colored magenta) enables the subsequent formation of a new elongating junction between the left and right SEs (outward double-arrowheads colored yellow). (B) The rearrangement of apical junction during zippering in the Ciona embryo is shown in the same manner as in (A). (C) The cell shape change accompanying unscheduled cell division interrupts the shrinkage of apical junction.
