Fig. 4. Comparison between E15 trigeminal ganglia from (A) midbrain control, (B)
cardiac and (C) trunk neural crest chimera. Although cardiac and trunk chimera
ganglia are smaller than the midbrain control, the ophthalmic (op) maxillary
(mx), mandibular (mn) and trigeminal motor nerve (m) all look normal. D is a
statistical comparison of the relative areas of the ganglia.
