WormMine: ExpressionPattern Expr11416

• Pattern: Region N2 was expressed in the ventral nerve cord during the L1 larval stage. Expression of region N2 was also seen in some P cells and in the neural precursor Q cells.
• Primary Identifier: Expr11416
• Remark: Feature : "ceh-13/lin-39_temp_N2"

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
