Deer antlers are the fastest-growing tissue on Earth! They can grow an inch per day, and a large bull moose can grow an 80-pound rack in a single summer! This rapid growth is regulated by hormones and influenced by the amount of daylight.
Deer antlers initially develop a soft, velvety covering that is rich in blood vessels and nerves, making it sensitive. This "velvet" is shed once the antler is fully grown.
The rapid growth of antlers is made possible by a unique combination of factors, including:
- Abundant blood supply: Antlers receive a large amount of blood, providing the nutrients needed for rapid growth.
- Specialized cells: Antlers are composed of specialized cells that are capable of dividing and growing at a rapid pace.
- Hormonal regulation: The growth of antlers is tightly controlled by hormones, particularly testosterone.
While cancer cells can grow quickly, they are not the fastest-growing tissue in the body. Cancer cells are abnormal and grow uncontrollably, invading surrounding tissues and causing damage.
