WormMine: ExpressionPattern Expr7988

• Pattern: mom-2 expression was observed in early embryos, at approximately 0-2 hours after egg laying, and continued throughout embryonic and larval development. mom-2 was expressed slightly earlier in embryogenesis than cwn-1 or cwn-2. Expression of mom-2 continued throughout embryonic and larval development. Expression of mom-2 was observed in body wall muscles, ventral cord neurons, intestinal cells and fused and unfused seam cells throughout larval development. mom-2 expression was also observed in head cells between the anterior and posterior bulbs of the pharynx. During the L3 and L4 stages, mom-2 was expressed in the descendants of P5.p to P7.p. No expression of mom-2 was observed in the anchor cell (8/8 lines).

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
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.	body wall musculature	body muscle	WBbt:0005813
