In the embryo, the upstream promoter (ten-1a) is most active in the descendants of the C and EMS blastomers. During postembryonic development, GFP expression was detected in the pharynx, gut, coelomocytes, posterior body wall muscles, vulva muscles in hermaphrodites, and diagonal muscles in males. The ten-1a promoter is also active in some hypodermal cells including the hyp-11 cell, hypodermal seam cells, and rectal hypodermis. In the somatic gonad, it is active throughout its development starting with z1 and z4 cells in the embryo. During gonad development, it is expressed in the distal tip cells and the linker cell in males, in gonad and spermatheca sheath cells, and the utse cells of the uterus. In males, ten-1a is active in the vas deferens and spicule socket cells. Furthermore, GFP expression in DVB neurons and a few ring interneurons could be detected.

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.
Longitudinal bands of muscle cells surrounding animal body, with one band running in each quadrant of the body, regulated contraction and relaxation of these muscles cause locomotion.
the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.
A free-floating spherical cell lying in the pseudocoelomic cavity of larvae and adult C. elegans which can endocytose many compounds, possibly for immune surveillance. There are six coelomocytes in adult hermaphrodites, and they display prominent cytoplasmic inclusions and vacuoles.
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.
That portion of the male reproductive tract, through which sperm are delivered to the proctodeum and then the cloaca in the tail. Thus that portion which is distal to the testis, made of a total of 30 cells.
membranous cell attaches the uterus to the lateral epidermis (seam) and forms a thin laminar process dorsal to the vulva. formed by fusion of eight pi cell progeny and AC.
