Why can lizard tails reproduce themselves?

Researchers at Scripps Research Institute in San Diego, California (USA) have discovered that myoseverine - a molecule - when reversed cell differentiation will play a fundamental role in Help the lizard to recreate their tail when it breaks off for some reason.

Accordingly, it is thought that normally when forming the muscles in the fetus, some muscle cells will divide into myocytes, which is a key component of muscle fibers. In the case of lizards whose tail is broken, the myoseverine molecule begins to be synthesized.

It will affect a number of factors of growth, bone destruction and upset the differentiation of cells. Myocytes regress to become myoblasts, gradually develop and regenerate the lizard tail. At the same time, the myoseverine molecule promotes the synthesis of many proteins that are useful for healing the scarring where the tail breaks.
