In adult hermaphrodites, F22A3.1 reporter expression was observed in the inner and outer labial socket cells of the head. F22A3.1 is expressed strongly in the seam cells within the hypodermal ridges, which extend bilaterally along the length of the exterior body wall. During the first larval stage, F22A3.1 also demonstrated expression in P-cells, the ventral hypodermal precursors, some of which form the vulva. In general, F22A3.1 seems to be quite specific to hypodermal tissues and is probably expressed in all hypodermal cells including glial-like cells.
