Fig. 11. MyHC-positive quail cells (arrows) are present in the root of the
trigeminal ganglion. Epineural connective tissues and endothelial cells within
the ganglion and brainstem were found in all transplant categories, but only
segmental plate grafts generated myotubes within the ganglion. The other quail
cells evident within the trigeminal root are endothelial cells. An ectopic
muscle is visible to the left. A stage 29 embryo is shown.
