WormMine: ExpressionPattern Expr13568

• Pattern: ztf-6::gfp expression is first observed in late embryogenesis (threefold stage). In early larval stages, the ztf-6::gfp-expressing cells include head hypodermal cells, head muscle cells, neurons, and ectodermal blast cells along the body (all P and all V cells) and in the tail. Starting in the L2 stage, additional neurons in P cell-derived ventral cord motor neurons express ztf-6::gfp. Because of the postdeirid loss phenotype of ztf-6 mutants, we examined the postdeirid lineage in more detail. We observe ztf-6 expression in the V5 cell of freshly hatched L1 animals. Upon division of the V5 cell into a posterior and anterior daughter, we observe expression in both the anterior and posterior daughters of the V5 cell. The descendent of the posterior V5.p daughter, V5.pa (the founder of the postdeirid lineage), and V5.pp also continue to express ztf-6::gfp. Within the V5.pa lineage, expression of ztf-6::gfp is retained in the blast cells that generate the glial cells and the PDE and PVD neurons (v5.paaa, V5.papa, V5.paap, V5.papp). No expression is detected at later stages in this lineage.

Blast cell lying ventrolaterally in the late embryo and L1 larval stage which divides during the late L1 larva in stereotypical reiterated fashion to give rise to many motor neurons which begin function in the ventral cord and preanal ganglion of the early L2 larva, as well as hypodermal cells (which fuse into hyp7) and a series of programmed cell deaths. In addition, the Pn.p daughters of P3 through P8 lineages persist without fusing into the hyp7 syncytium until mid L3 stage when they can be induced to divide further to produce vulval epithelial cells (vulA - vulF) or more hyp7 cells.
