WormMine: ExpressionPattern Expr2300

• Pattern: Indistinguishable expression patterns were observed using both methods. EFN-4 was first detected at about the 100-cell stage in a large number of ventral surface cells, identified as neural or epidermal precursors. During and after enclosure of the epidermis, EFN-4 was expressed in many neurons and not in epidermal cells. In later embryos, larvae and adults, EFN-4-GFP was expressed in several head neurons, pharyngeal cells and a small number of lateral and tail neurons, within which EFN-4 was localized throughout the neuronal cell body and in axonal processes.
• Primary Identifier: Expr2300
• Subcellular Localization: EFN-4 was localized throughout the neuronal cell body and in axonal processes.

The left and right lateral ganglia lie beside the nerve ring in the head. They each contain about (30) neuron cell bodies and send their neuronal processes into the ring at its posterior margin either laterally or ventrally via the amphid commissures and ventral ganglion, but form no local neuropil separate from the nerve ring. The lateral ganglia are in close contact with the lateral hypodermal cords.	lateral ganglion	lateral ganglia	WBbt:0005105
