Expression Pattern :

Pattern  GFP was localized to the intestine and neurons in embryonic, larval and adult animals. The earliest observed GFP signal was present in 3-fold or pretzel stage embryos (M.A.P. unpublished data). Intestinal expression is fairly even throughout the length of the intestine of early animals (embryonic and larval stage 1 animals) but becomes weaker in the mid-intestine from larval stage 2 onward. Neuronal expression is robust throughout life, with many neurons in the head region apparent. Primary Identifier  Expr9662

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

  The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch. L4 larva Ce WBls:0000038
  The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch. L1 larva Ce WBls:0000024
  The C. elegans life stage spanning 520-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage. 3-fold embryo Ce WBls:0000020
