Supplementary Fig. 7.

Motor neuron heterotopia after treatment with shPTPγ vector Si1. Si1 DNA was electroporated at HH10–11, and HH22 sections were analysed with immunofluorescence microscopy. An example is shown of Isl1/2-expressing motor neurons aberrantly localised to ventricular sites (arrows). A and D are two sections from one embryo, with D at enlarged scale. Scale bar = 50 μm (A–C), 25 μm (D–F).
