Representative lateral views (optical section) of the forming trigeminal ganglion in an HH16 chick head after electroporation of a 5 bp mismatch control Annexin A6 (A-C) or Annexin A6 (D-F) MO at HH10. Trigeminal ganglia electroporated with the control MO exhibit a condensed, organized morphology, with forming nerve bundles, as seen by Tubb3 immunostaining (C, arrows), while those electroporated with the Annexin A6 MO possess a disorganized and dispersed morphology, with neurons present throughout the embryo head (F, arrows). Scale bar, 50 μm (A) applies to all images.
