Skin type and antlerogenesis. (a) Deer nose snout (asterisk). (b) The ventral surface of a deer tail (asterisk). (c) and (d) Nude mouse skin (arrow). Note that all these three hairless skin types are incompetent to interact with the grafted AP to initiate antler formation; even if wounding (arrow) was carried out, no antler growth occurred (d).
