Fig. 6

Expression of Emx at late developmental stages in embryos of the onychophoran E. rowelli. Anterior is left in a, d, e and up in b, c, fh; developing limbs are numbered. a Stage IV embryo in lateral view, dorsal is up. b Detail of a stage IV embryo in ventrolateral view, dorsal is right. c Same detail as in B, superimposed light micrograph and DAPI image. d Anterior developing limbs of a stage IV embryo in ventral view. e Developing third to sixth legs of the same embryo as in D in ventral view. f Head of a stage IV embryo in ventral view. g Head of a stage V embryo in dorsal view. Arrows point to uncharacterized regions of the developing brain, arrowheads indicate the putative olfactory lobes. h Anterior trunk of a stage V embryo in ventral view. Arrowheads indicate the expression in the developing ventral nerve cords. Abbreviations: an, antennal tracts; at, developing antenna; cl, cephalic lobe; cn, central brain neuropil; cx, brain cortex; de, dorsal extra-embryonic tissue; jw, developing jaw; po, proctodeum; sp, developing slime papilla; st, stomodeum; ve, ventral extra-embryonic tissue Scale bars: a: 500 μm; b, c, fh: 200 μm; d, e: 100 μm
