It’s well known that some reptiles, like salamanders, are able to regenerate a great number of their body structures such as limbs, tails, jaws, and even parts of their organs such as the heart, brain and spinal cord. Recently, a team of Australian researchers led by Dr. Godwin discovered that the white blood cells called macrophages play a key role in this muscle regeneration.
Where it gets interesting, is that macrophages also exist in the human body. The term, which means ‘big eaters’ refers to the cells ability to eat up dead cells and germs within the body, thus helping our muscles to repair and grow. Earlier studies have also revealed that stimulating macrophages can help the synthesis of collagen in our skin, which leads to optimal results in skin rejuvenation.
While it might still be too early for scientists to determine how we can regenerate complete arms or legs as salamanders do, they may be able to let people heal wounds without forming visible scars, or make more advanced anti-aging products in the very near future.
