Expression Pattern :

Pattern  MRG-1 is highly enriched in nuclei and concentrated on chromatin. In early embryos, MRG-1 is present in the nuclei of all blastomeres. In late embryos and young larvae, MRG-1 staining is higher in the nuclei of the two primordial germ cells, Z2 and Z3, than in somatic blastomeres. In larvae and adults, MRG-1 staining is seen primarily in the nuclei of germ cells, although it is also faintly visible in the nuclei of several somatic cell types, including intestinal cells. In the adult germ line, all germ nuclei in the mitotic and meiotic regions are stained. These results demonstrate that MRG-1 is present in the germ line at all stages of development and is maternally loaded into embryos. In addition, zygotically expressed MRG-1 is produced in all cells by at least the 100-cell stage; it accumulates to higher levels in the primordial germ cells than in somatic tissues.

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
