Expression Pattern :

Pattern  No SRP-3::lacZ expression was evident during embryogenesis. However, SRP-3 expression was visible in all stages of the nematode postembryonic development. In the early larval (L2) stage, lacZ staining was noticeable in the posterior intestinal and anterior muscle cells. In the late larval (L4) to adult stages, lacZ staining can be seen in the body wall muscles, particularly in the anterior region of the worm. To visualize SRP-3 expression in live, intact animals, transgenic animals expressing srp-3::gfp fusion constructs also were generated. Consistent with the lacZ data, srp-3-directed GFP expression was evident throughout postembryonic development. However, expression was restricted primarily to the anterior muscle cells.

Definition Name Synonym Primary Identifier
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
