Stem-cell/tissue transplantation and ectopic organogenesis. (a) HF (arrow) was formed from the bulge that was transplanted inside the fetal dermal tissue (reproduced with permission from [18, Figure 4D]). (b) Antler (arrow) was formed from the antlerogenic periosteum (AP) that was subcutaneously transplanted onto the forehead of a male deer calf.
