The archenteron cells were stretched along the axis of the archenteron (B-D or E), and resumed a cuboid shape (F). In contrast, both the ectodermal and endodermal cells in 5. mirabilis embryos remained elongated along the apico-basal direction during the later stages of invagination (G-L). 100 n 75 5(1 25- | 0- DJj n > c \~ 100 V t at 75 a SO 25. -2 o X.
