Posted: 20 May 2013 01:37 PM PDT Salamanders' immune systems are key to their remarkable ability to regrow limbs, and could also underpin their ability to regenerate spinal cords, brain tissue and even parts of their hearts, scientists have found. In new research, scientists have found that when immune cells known as macrophages were systemically removed, salamanders lost their ability to regenerate a limb and instead formed scar tissue.

New source of kidneys for transplant suggested Posted: 20 May 2013 01:36 PM PDT Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs?
