People can regenerate lost legs and arms

A new discovery by scientists in salamanders can help people find therapies for restoring dead legs and arms.

If the leg or spinal cord of the salamander breaks off, they can be restored by the immune system's special ability. They can even restore brain tissue or heart tissue.

To explore the ability of salamanders to regenerate body parts, a team of Monash University experts in Australia analyzed their immune systems. They pay attention to macrophages - a type of immune cell , Science Daily reported. When the team removed the macrophage, the broken limbs of the salamander could not recover. This fact shows that macrophages are the type of cells that help salamanders recover lost body parts.

"Our findings help the scientific community better understand the conditions necessary for the regeneration of body parts. We can control that process and can even bring it into the human body , " proceeds. Dr. James Godwin, the lead researcher, said.

In addition, according to Godwin, studying the regeneration of salamanders can help scientists find new therapies to treat heart disease, kidney disease, nerve damage and many other diseases.

Some previous studies show that many animals have the ability to recover broken limbs. But gradually that ability disappears during evolution.

"It's likely that regeneration is still lurking in the human body. We hope scientists will awaken that ability. They need to know exactly the regeneration process in the salamander body to be able to create regenerative therapies for humans, ' Godwin commented.
