WormMine: ExpressionPattern Expr2382

• Pattern: GFP was predominantly expressed in head neurons, a few cells in the tail and hypodermis except for seam cells. A total of 30-50 fluorescent neurons of varying intensities were observed in the head. Stronger or more consistent expression was observed in RMDV, RMD, SMDV, RIB, ASK and probably RMDD and SMDD neurons. Expression in AWC, ASE, AVJ and ASH was sometimes seen. In the tail, DVB and DVC neurons were probably expressing. GFP was also expressed in ventral cord neurons and intestine, typically near the tail. L2 and L3 larvae show extensive expression most notably in head neurons and hypodermis, and the expression is weaker in L4 and adults. Expression is also seen in later embryos.

neuron with cell body associated with the ventral nerve cord.	ventral cord neuron	ventral cord motoneuron	WBbt:0005300
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
