Why can antler regeneration?

The main deer is the only species among mammals capable of fully regenerating a body part - such as their antlers. Professor Joanna Price of the Royal College of Veterinary Medicine said that antlers are large structures made up of bones and grow gradually over time.

This part can grow completely in about 3-4 months and at that rate, it becomes the fastest growing living tissue. After reaching the maximum size, the gauze will begin to harden and the soft, dark skin on the outside will gradually fade.

When the skin shed, only the bones remained and it became a sharp weapon in fights. Usually, at the end of the double season of deer, the antlers also automatically shed to conserve energy.

Waiting for the next spring, a new pair of antlers will sprout from the bone tissue from the top of the animal's head.

Professor Joanna Price and researchers speculate that stem cells - the type of cells capable of differentiating into many specialized tissue types - are the basis of this self-regeneration process. Regulating it is some form of signaling, which can be caused by hormones like estrogen and testosterone.
