WormMine: ExpressionPattern Expr4378

• Pattern: The C17E4.3::GFP reporter is expressed in the developing embryo and L1 larval stages, in three distinct sheath/socket cells in the head region close to the anterior bulb of the pharynx and several cells around the anus. Expression is also seen in several pharyngeal muscle cells. Dye filling tests confirmed that the processes extending to the nose were not from amphid neurons, but rather from socket cells.
• Primary Identifier: Expr4378

type of cells that make up muscle layers in the pharynx.	pharyngeal muscle cell		WBbt:0005451
cells that support sensory neurons, similar to glial cells in vertebrates. A category which collectively refers to socket cells, sheath cells, and structural cells, or their processes. All of these cells extend long processes which serve a supporting role, rather like glia, to form a protective environment around sensory neuron endings. In addition, some of these cells extend broad thin processes from their somata which wrap around neuronal ganglia, again in a glia-like fashion	accessory cell	support cell	WBbt:0005762
