Fig. 7. pax6 expression in the 72 hour episphere. Figure shows pax6 expression in 72 hour young worms in a series of optical sections from a ventroanterior view. (A) Surface view showing pax6 expression in larval eyes (white arrows), antennae (ant) and palpae (plp). (B) Deeper optical section with pax6 expression in larval eyes (le, white arrows) and anlagen of the palpae. (C) More dorsal optical section showing pax6 expression in antennae (ant), besides prominent expression in palpae.
