WormMine: ExpressionPattern Expr19

• Pattern: Adults show 4 nuclei in the head ganglia; 2 large nuclei in the mid-body of the worm adjacent to either hypodermal ridge, one close to the vulva and one a little anterior to it; and 2 (neuronal?) nuclei in the tail. The head ganglia nuclei are present at hatching, the mid-body and tail cells start to stain at later larval stages. Also in adults, ~4 body-wall muscle cells in the posterior half of the body can be seen (usually only after relatively long periods of incubation). Five nuclei of cells of the of the head ganglia show expression from L1 onwards. Mid-larval stages mark the emergence of two more spatially distinct pattern components, both of which remain in place through the rest of the life cycle. The cell bodies of the CANL/R cells can be identified in the lateral mid-body. In the tail, two more nuclei show expression. One seems to be a member of the tail ganglia neurones, the other is possibly one of the intestinal muscles.
