Fig. 6From: Expression of NK genes that are not part of the NK cluster in the onychophoran Euperipatoides rowelli (Peripatopsidae)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, f–h; 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, f–h: 200 μm; d, e: 100 μmBack to article page
