LacZ activity is seen in ten cells at 20 degree: the six touch receptors ALML/R, AVM, PVM and PLML/R cells. and the FLPL/R and PVDL/R neurons. In adults that began to lay eggs, one or two cells in the vulva region and anterior to FLP were stained. In older adults, one to seven neurons in the ventral cord between the vulva and the preanal ganglion, and two cells that may be AIZ cells, the FLP sisters. Animals overstained show touch cells, FLP, PVD.
