Expression of differentiation genes during larval development. a-h WISH of neuronal genes Mfu-Elav1, Mfu-Syt1, Mfu-Rab3. i FISH of Mfu-Syt1combined with IHC of acetylated-tubulin in the posterior region. j-l FISH of Mfu-POU4. Inset in (j) shows the expression of Mfu-POU4 in the anterior region. Arrowheads point to the posterior pioneer neuron, while arrows point to the neurons adjacent to it. Scale bars: 20 μm
