ABSTRACT
Skeleton pattern formation was examined in chick wing bud grafts using the chorioallantoic grafting method. The distal parts of the wing bud were excised from the donor wing and transplanted onto the chorioallantoic membrane (the experimental groups). Transplants with intact limb bud material served as the control group. The skeleton pattern formation in the grafts depended on the amount of transplanted material and donor's limb bud stage. The younger the donor's stage and the bigger the piece of the transplanted material the more proximal parts grafts had, more retarded growth and abnormal skeleton in the zeugopod and autopod was. The percentage of the signs of insufficient blood supply in the experimental groups was less than that in the control group. As the amount of the transplanted limb bud material decreased and donor's limb bud aged, post-axial polydactyly changed to the pre-axial one.
