Fig. 3. Ectopic muscle differentiation perturbs the axonal projections. Four days after electroporation of embryos with mouse MyoD, transverse sections with mouse MyoD, were successively incubated with the monoclonal antibodies, MF20 (green, A) and 3A10 (red, B), in order to recognise differentiated muscle cells and axonal projections, respectively. (C,D) Merged pictures from A and B showing the absence of overlap between the two antibodies.
