WormMine: ExpressionPattern Expr9974

• Pattern: GFP fluorescence appeared exclusively neuronal during development from about the 1.5 fold stage of embryogenesis through to the adult. No obvious RHGF-2s::GFP fluorescence was visible in the earlier stages of embryogenesis. Many, but not all, of the 302 C. elegans hermaphrodite neurons expressed GFP in the transgenic animals examined. Several cell bodies in head and tail ganglia and many neuronal processes in the nerve ring and ventral cord were visible, with the GFP fluorescence for most cells distributed diffusely throughout the cell, although there were instances of more punctate fluorescence within some cell bodies and processes, particularly in the ventral cord. Neurons that were positively identified in late larval/adult animals based on their position and morphology were the ALM, AVM, PLM and PVM mechanosensory neurons and the BDUs. Expression from the ciliated sensory neurons, most ventral cord motor neurons and neurons with cell bodies in the mid-body of the animal such as the CANs, PDEs and SDQs, for example, was notably absent from transgenic animals observed at late larval and adult stages.
