Abstract
- The formation of supernumerary limb structures was studied by juxtaposing normally nonadjacent embryonic chick limb bud tissue. Different “wedges” (ectodern and mesoderm) of posterior donor right wing bud (stage 21) were transplanted to a slit made in stage 20–23 host right wing buds. Donor posterior tissue was transplanted to an anterior position in a host wing bud or, as a control, to the same position as its position of origin. Transplanting different wedges of posterior tissue to the same anterior host position results in wings with supernumerary structures, and different extra structures form depending on the position of origin of the donor tissue. The identification of extra limb structures formed was based on the skeletal and integumentary patterns of resulting wings and the pattern of muscles as seen in serial sections of resulting limbs. The results of experiments presented here are considered in light of current models that have been used to describe the formation of supernumerary limb structures by the embryonic chick limb bud.
