Fig. 3. The MS cell fate regulators TBX-35 and CEH-51 are required for normal gastrulation timing in the MS lineage.

Fig. 3

Images from a movie of a wild-type embryo (A–E) and a tbx-35(tm1789);ceh-51(tm2123) embryo (F–J). Dark blue represents the MS descendants that normally internalize after the fourth MS cell division, and the light blue represents the MS descendants that normally internalize after the fifth MS cell division. Colored arrowheads mark positions where cells internalized. (A) MS8 stage. (B) MS16 stage (C) 12 MS descendants have internalized (arrowheads). 4 MS descendants remain on the surface. (D) After the 4 MS descendants remaining at the ventral surface have divided. (E) These MS descendants have internalized. (F–J) tbx-35(tm1789);ceh-51(tm2123) MS descendants at similar stages, showing both premature and late cell internalizations compared to wild-type. Lineages at the top of the figure are drawn from these two embryos. Times are minutes after beginning of MS8 stage. Scale bar: 5 μm.
