Around that time, a mass of stem cells and a hefty amount of blood vessels have arrived at the site. But the biological secrets inside their arm regeneration feat do hold the promise of learning more about how we might better regenerate our own diseased or lost tissue. “AChE protein may have an important influence in the process of arm regeneration,” the researchers noted in their paper.

Only the biochemistry in their bodies had already started changing. But they could help make the octopus a new scientific model for researchers looking to study regeneration. They do develop an instinctive urge to mate as the age of maturity arrives. The octos were put under anesthesia and a small tip (just one to two centimeters) from each arm was removed.
