To the right is an image of a Feulgen stained section showing quail cells on the left and chick cells on the right. Surgical Construction of Quail-Chick Chimeras of the Nervous System Diagram showing a host chick's neural tube and neural crest cells being replaced with a donor quail's neural tube and neural crest cells. Sequence showing the injection of India ink beneath host chick embryo to help see the almost transparent embryo in ovo. Feulgen stained transverse section through the host chick embryo containing the grafted quail nerual tube and neural crest. Host one day after receiving quail graft.
Donor quail neural crest are adjacent to the dorsal quail neural tube.
Newly hatched quail-chick chimera. This newly hatched chimera has normal sensory and motor activity throughout its body. Young quail-chick chimera with wings extended to better show pigmented quail feathers at the level of the graft.
