Quail-Chick Transplantation in the Embryonic Limb Bud
Chick and quail have been powerful partners in the investigation of avian development. Cells from these two species can develop harmoniously in heterospecific combinations, yet each remains histologically distinct, facilitating the fate mapping of transplanted tissues (1). This property of the quail-chick chimera has been used to track cell position and fate in many embryonic processes including gastrulation (2, 3, 4), neural tube formation (5), hematopoiesis (6), and craniofacial development (7, 8, 9) among others. One of the most accessible areas for such grafts is the embryonic chick limb bud, site of many pioneering manipulations (10; for review, see ref. 11). Quail-cell grafts have been used to investigate the origin of the limb bud from somatopleural mesoderm (12), the contribution of the somites to limb musculature (13, 14, 15, 16), and the effect of limb mesoderm on species-specific limb development (17).
