WormMine: ExpressionPattern Expr949

• Pattern: gfp is expressed in a variety of cells, including the HSNs; hyp 8, 9, and 10; B; F; rect D; DVC; some ventral cord neurons; cells in the head; and cells in the preanal ganglion. sem-4 gfp is expressed in the VPCs. Expression in the VPCs is first observable during L2 and persists in the vulval lineages until the vulval divisions are complete. Expression is undetectable again by the mid-L4 stage, before vulval morphogenesis has terminated. Expression of sem-4 gfp in vulval cells is often strongest in the descendants of P7.p.
