Expression Pattern :

Pattern  GFP showed bright expression in the adult posterior intestinal cells and also very strong expression in a cluster of three to four cells posterior to the intestine. Morphology indicated that these cells possibly included the three rectal gland cells. Rectal gland expression is supported by single cell transcript analysis (Packer, et al. 2019). Additionally, we often saw one or two green cells in or near the bend in the anterior and/or posterior germlines. We observed at least one of these germline-localized cells in ~70% of L4-adult worms, although it is possible that expression was sometimes obscured by the intestine and that this number is higher. These cells looked similar in appearance to the expression in the posterior intestinal cells, but were localized outside of the intestine. Based on their position and appearance, we hypothesize that the expression is in sheath cell nuclei. Although one cell was often bright in appearance, these cells were generally dimmer than the intestinal and posterior extra-intestinal cells. Primary Identifier  Expr16349

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

five pairs of thin gonadal sheath cells form a single layer covering the germ line component of each arm, each pair occupying a stereotyped position along the gonad proximal-distal axis. gonadal sheath cell   WBbt:0005828
