Mid-stage test cell larva. Confocal scan of a larva stained for F-actin (red) and DAPI (cell nuclei, blue). Anterior faces up. Note the staining of the F-actin-rich neuropil (np) underlying the (nuclei of the) cerebral ganglia. The dashed line indicates the prototroch. Abbreviations: nuclei of the developing cerebral ganglia (cg); developing foregut (fg); neuropil of the cerebral ganglia and cerebral commissure (np); peri-imaginal space (pis); spicule-secreting epidermal cells of the outgrowing trunk (sp); location of mouth opening (asterisk). Scale bar: 50 μm
