Fig. 7. ceh-20 is expressed in nuclei of Q, P and V cells and their descendants. (A-C) Fluorescence micrographs of wild-type larvae carrying ceh-20::gfp. This plasmid rescued the cell migration defects (QL and QR descendants, BDU) and the multivulval defect of ceh-20(mu290) animals. Dorsal is upwards and anterior is towards the left. (A,B) At hatching, ceh-20 is expressed in the nuclei of ectodermal such as the Q cells, P cells, V cells and hyp7. The mesodermal precursor, M, also expresses ceh-20 robustly. (C) Six to eight hours after hatching, V cell daughters, hyp7 cells and P cells continue to express ceh-20. In this animal, the right side is shown. The descendants of QR have migrated anteriorly and are in the process of dividing (not visible by fluorescence). (D) In this L2 animal, P(1-11).p cells express ceh-20, although only P(3-8).p are shown. Ventral cord neurons between the Pn.p cells also express ceh-20::gfp.
