Fig. 10From: Involvement of Slit–Robo signaling in the development of the posterior commissure and concomitant swimming behavior in Xenopus laevis Schematic view of the result of the experiment. In the control, Robo2-expressing PC axons extend through the Slit2-weak region in the posterior diencephalon and result in a tight bundle. However, in the slit2-/robo2-MO-injected larvae, the PC makes elongates anteriorly with a defasciculated tract, due to the absence of repulsive interaction between Slit2 and Robo2.
