3 Expression Patterns

• Primary Identifier: Expr3278
• Pattern: In the embryo, the upstream promoter (ten-1a) is most active in the descendants of the C and EMS blastomers. During postembryonic development, GFP expression was detected in the pharynx, gut, coelomocytes, posterior body wall muscles, vulva muscles in hermaphrodites, and diagonal muscles in males. The ten-1a promoter is also active in some hypodermal cells including the hyp-11 cell, hypodermal seam cells, and rectal hypodermis. In the somatic gonad, it is active throughout its development starting with z1 and z4 cells in the embryo. During gonad development, it is expressed in the distal tip cells and the linker cell in males, in gonad and spermatheca sheath cells, and the utse cells of the uterus. In males, ten-1a is active in the vas deferens and spicule socket cells. Furthermore, GFP expression in DVB neurons and a few ring interneurons could be detected.

• Primary Identifier: Expr1032
• Pattern: In wild-type worms, expression of cat-2::gfp reporters was restricted to the 14 cells previously identified by a formaldehyde-induced fluorescence (FIF) assay for DA(CEPd, CEPv, ADE, PDE, R5A, R7A, R9A), plus 4 additional male-specific FIF-positive cells identified here for the first time. These are the four socket cells of the spicules.

• Primary Identifier: Expr630
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
• Pattern: egl-17 expression is observed in several cells of the B lineage and the Y.p progeny Y.p(l/r)aa during L3 lethargus. The cells from B lineage appear to be in two of the socket cells, one on each side (likely _(l/r)d), B.paa and B.pppa). At the end of L4 lethargus, expression is observed in a cluster of socket cells per spicule. Shortly after male reaches adulthood, expression is maintained only in B.paa cells.

Definition	Name	Synonym	Primary Identifier
An interfacial epithelial cell which forms a distal cap on a sheath cell to bind the sheath of a sensillum to the neighboring hypodermis, via adherens junctions. There is often a narrow opening through the socket from the exterior into the sheath channel, allowing ciliated dendrites to be exposed to the external environment. The socket cell functions similarly to a glial cell.	socket cell		WBbt:0005750
