Fig. 7. Cell-shape changes in ingressing cells. Images are of living embryos (A,B,E) or are confocal sections of fixed embryos after immunostaining for NMY-2 (C,D,F). (C,D,F) Confocal sections. All embryos are oriented as in Fig. 4D, and arrowheads indicate apical surfaces. (A-D) The E daughters are indicated (yellow asterisks) before ingression (A,C) and during ingression (B,D). (E-F) Ingression of MS descendants (red asterisks). MSapaa is shown in (E) and two of the MS ‘wishbone’ descendants are shown in (F), in which NMY-2 is green and DNA blue. A,B,E and F are shown at twice the magnification of C and D.
