Expression of Nedx at stage IV embryos of the onychophoran E. rowelli. Anterior is left in a, c–f and up in b; developing limbs are numbered. Filled and empty arrowheads point to the spot-like expression dorsal of the developing limbs and the longitudinal mesodermal domains within the limbs, respectively. Asterisks indicate the longitudinal band of expression connecting the spot-like domains. a Head in ventrolateral view, dorsal is up. b Head in ventral view. c–f Consecutive developing limbs in lateral view, dorsal is up. Abbreviations: at, developing antenna; cl, cephalic lobe; jw, developing jaw; sp; developing slime papilla; ve, ventral extra-embryonic tissue. Scale bars: 200 μm
