• Primary Identifier: Expr10005
• Pattern: At the onset of pocket closure, the plx-2 reporter expresses in six blast cells (and sporadically in a seventh) on the surface of the open ventral pocket, five of which, after dividing, form a band of ten PLX-2/plexin expressing plexin band cells that extends across the midline spanning the open pocket. At the onset of pocket closure, the plx-2 reporters express in right and left side analogs of QV5 and P cells P3/4, P5/6, P9/10, P11/12. The reporter also expresses in bridge and scaffold cells, which together comprise a band of PLX-2 and VAB-1 expressing cells that cross the open pocket. Expression in all of these cells continues throughout pocket closure and beyond. Among the P cells, expression is most prominent in P9/10 right (R) and left (L).

Definition	Name	Synonym	Primary Identifier
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. P0 is also known as W.	ventral cord blast cell	P cell	WBbt:0008115
