Abstract: 

Autologous transplantation of antlerogenic periosteum to the metacarpal
region of a fallow buck resulted in the formation of an ectopic pedicle
within a few months after transplantation. In the following years the
pedicle increased in size, but no ectopic antler development occurred.
However, in the ninth year after transplantation a first antler of about
3 cm length grew from the ectopic pedicle. The hard ectopic first
antler was not cast, and renewed antler growth, starting in late spring
of the following year, led to the formation of a larger subsequent
antler of 7.3 cm length. The latter exhibited a distal flattening
(palmation) and a rudimentary basal coronet, thereby displaying
morphological features typical of the subsequent antlers of fallow
bucks. The results of the experiment indicate (1) that transformation
from pedicle to antler growth can occur several years after pedicle
initiation, when the pedicle has reached a certain threshold size, (2)
that species and age specific features of antler morphology tend to be
realized even in ectopic locations, and (3) that primary and subsequent
antler growth was apparently triggered by cells of the pedicle
periosteum, being derived from the transplanted antlerogenic periosteum.
The findings thereby emphasize the importance of local factors in the
control of pedicle/first antler transformation and antler morphogenesis.
