A comparative study of myogenic cell invasion of the avian wing and leg bud.
The borders of myogenic cell invasion of avian wing and leg buds were determined using the interspecific grafting technique between quail and chick embryos. Distal parts of quail limb buds were grafted ectopically into the coelomic cavity of chick embryos. The presence or absence of skeletal muscle was investigated in histological sections of the reincubated grafts. A comparison between the borders of myogenic cell invasion of the wing and leg buds showed that the differences in the position of the distal most muscles in the adult avian limbs could be a consequence of the cranio-caudal sequence of development.
