EggFIG 8: Interactions between the AC and cells of the developing vulva.

DIC/epifluorescent images, lateral view, left side, of cdh-3::GFP transgenic animals at various stages of the vulval cell lineage. The reporter gene is expressed in the anchor cell (AC; arrowhead) at all stages shown.
A. Pnp stage. Early–mid L3.
B. Pnpx (two-cell) stage. Mid L3.
C. Pnpxx (four-cell) stage. Mid-late L3.
D. Pnpxx/Pnpxxx (six- to eight-cell) stage. L3/L4 molt. Magnification, 1000x. (Strain source: D. Sherwood and P.W. Sternberg.) (Based on Sherwood and Sternberg, 2003.)
