WormMine: ExpressionPattern Expr11704

• Pattern: Expression of the transcriptional fusion Ptop-1::gfp was not detected in early embryonic cells due to maternal germline silencing of the multi-copy transgenic gene. The GFP expression, however, was observed in most cells at the late embryonic stage and decreased with larval development. In the larval stages, GFP expression was predominantly present in the neuronal system, including sensory neurons (ILso, URX, RIC, IL1/IL2, AIY/AIM and RIG/RIF), motor neurons (VC4, VC5, HSN, PVD and PVM) of hermaphrodites and tail neurons (SPD and SPV/SPC) of males. The expression of the transcriptional fusion Ptop-1::gfp was strong in DTCs during the L3-L4 stage when gonad migration proceeds.

A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772
